Prox PRD - Phone Separation Alert Device | Stop Forgetting or Leaving Phone Behind at Home, Work, Restaurant, or Car | Proximity Alert Notification Approx 50-150ft | Stay Connected | No Subscription

JMFor the fact I previously owned a retail communications business some years back, I was asked at times to give technical reviews on certain products that were new to the marketplace. A previous commercial client asked me to give him my personal opinion as to the reliability of this newly marketed device that came out late last year and is produced by the company, Prox Devices, Inc. The device is called the Prox PRD™ and is a “Notify When Left Behind” or “Never Leave Behind” type device that can be identified by the newly given acronyms, “NLB” or “NWLB.”After ordering this product for myself back in December of ‘21, I have to say it may be the only electronic device I’ve ever purchased that has performed as well as its developer claimed it would.Having used it consistently since my purchase, I felt compelled to post a review to include much of what I shared with the previous client. After evaluating the Prox PRD™ over these last couple of months, I give the product a 5-Star rating.Prox Devices Inc. that markets the Prox PRD™, is based in San Jose, CA. The product has just one simple function, which is to help keep a person from losing their cellphone, and it can also prevent the loss of other Bluetooth enabled devices, such as tablets and laptops. Although its main purpose is to prevent these types of losses through one’s own carelessness, it still works well as an antitheft deterrent when placed in “travel mode,” as this will alert one to a potential theft or loss, regardless of whether the cellphone is moving away from the Prox PRD, or the PRD is moving away from the cellphone. So, the travel setting can easily prevent someone from skillfully picking up your cellphone and just casually walking away without your noticing, as you’ll immediately be alerted as soon as the PRD selected distance is met. This is particularly useful when you have set your PRD to its lowest setting of 10-15 feet. Distances will still vary depending on your surrounding structures, but the individual distance settings are remarkably accurate within what the company claims are the measured thresholds for each of the 5-alert settings.One of the PRD’s unique and most popular features is its ability to a function as a shutter button for your cellphone camera. This is convenient in making a selfie for yourself or when with a group, so you are not attempting to hold the cellphone and press the shutter button at the same time, which often ends up with one dropping their cellphone onto the ground, potentially severely damaging it if it lands on hard surfaces such as concrete and or sometimes deep water! None of these are an optimal choice.In looking at the other side of this for concerns in preventing annoying and unnecessary separation alerts, there’s also a “home mode” which helps prevent this from happening, since once you are in a safe location, such as your home, hotel room, or other familiar place, you do not want to be concerned with having your phone continually paired and connected to your PRD device. As a real-world setting, suppose you set your PRD down on a bedroom nightstand before going to bed, but then you get up in the middle of the night with your phone in hand to retrieve a charger in the kitchen. You may be well beyond the set separation alert distance but as long as your PRD remains “stationary” on the nightstand there will be no alert, which could certainly annoy or awaken your sleeping spouse.In my 2-month period of testing, I experienced only (3) false alerts. This is impressive in comparison to the scourge of bad reviews that go along with many of the electronic devices that fail to function properly and routinely sound false alerts due to their signals momentarily disconnecting from the devices. Some of the testing I did was within a few heavy RF use areas, and the PRD passed without incident while using it inside an international airport, several shopping malls and concert venues. So having no false alerts in those crowded RF areas show that the filter arrangement being implemented in the PRD, is clearly well engineered.First glance at the comprehensive user manual may appear extensive at first and this may put off a general type of consumer that may think the device is overly complex. However, it is truly not complicated, and the explanations and instructions are not to be feared, and one will appreciate and understand all the features after reading it all the way through. The level of thoroughness that is observed in the operations manual, aligns with its feature testing, and this led me to be much less concerned in the risk of bringing a PRD device into a quiet room format, such as a board meeting or church function, where the incidence of a signal disruption that creates a false alert, would be as embarrassing as having your cellphone ring aloud under those same circumstances.One of the best features of the Prox PRD is actually what it doesn’t have, which is the need for an App. This is a nice plus since there’s no concern of a company tracking you or your devices, and you can appreciate the fact your cellphone is not connecting or sharing any data with others, as it only connects to the PRD like any other Bluetooth device, such as a wireless speaker or headphones. Therefore, this is currently the best option in the present market to keep one from losing their phones or other Bluetooth devices, whether travelling locally in daily routines, or in faraway travels where the threat of leaving your laptop on a plane or cellphone at a foreign airport lounge, could certainly be disastrous.The PRD, as it comes right out of the box, is easy to set up and you can choose to use all the features it offers or just leave it on the average default setting as it is received. This is great to know, so that if one of your friends or family, who may be non-tech savvy individuals, but still needs one of these to help them from forgetting their phone, then as soon as the PRD is connected to their smartphone’s Bluetooth, it will still perform its task in keeping their phone, laptop, or tablet safe and so they will stay protected from the time they leave their home, stores, restaurants, or any other places they may visit along the way.I think it’s good to know that from a U.S. resident perspective, Prox Devices Inc. who’s developed the Prox PRD™, and sells it through Amazon, is a U.S. company and its components and programming are all done at its facilities in Silicon Valley. Therefore, any customer service needed in replacing a device or dealing with any problems that is outside of Amazon’s fulfillment capabilities, it can certainly be remedied more easily than having to solve the problems through an overseas customer service 1-800 line. There is a Q-code printed on the device that will take you back to the company’s operations manual in case you ever need help again with some of the features that are not already printed on the device itself. Overall, I think it is a great device for its simple function, and if used correctly, can and will prevent the tremendous angst and frustration that losing your cellphone causes, as well as the total monetary loss one suffers, whether by accident or theft!

I bought this as a Christmas gift for my mom. She always forgets her phone everywhere. She has been using it since she got it and loves it. She now keeps her phone near by all the times. It was very easy to set up with the iPhone and the sound is loud enough to hear it from one room to another.

I like this device. It's helped me keep track of my phone and keys, which I have a habit of laying down and leaving them. Only down side is that the device goes off randomly, and I think it's due to the frequency it uses things might be on the same frequency, I noticed it goes off when I pass electric power lines as well otherwise it is a helpful tool. I'll give it a five.

The Prox-PRD is working well for me; however, I do have some helpful observations: First, be sure and download the full User's Manual from the Prox website. It contains a lot of information about the finer points of using/configuring the device. Second, The Prox-PRD goes to sleep when it sits still for a short period of time. When it wakes up, it will always alarm, (1) to let you know that it can't detect the phone (out of range), or (2) to let you know that it has detected the phone (In range). When not driving somewhere, I keep my keys sitting on my bedroom dresser. Whenever I get something out of my dresser, the slight movement wakes up my Prox PRD and it alerts (regardless of where my phone is). I've gotten used to it, but some people may find it annoying. Same thing happens when I put my keys into a jacket pocket and hang the jacket on the back of a cafe/restaurant chair. All it takes is a slight movement of the chair to wake the Prox PRD and cause it to sound an alert.

I purchased this is May of 2025. For the year and few months I’ve had it, it was great. So helpful in stopping me from running out of my house and driving away before realising I forgot my phone. Then about a week ago, it stopped working. I figured it was the battery. Bought new battery. But, nothing. It’s just dead. Won’t turn on at all. I tried reinstalling the battery twice both ways and still no luck. If it was a 20 dollar device I’d be like, fine, a little over a year is good, I’ll just buy another. But for the price of this item, it should last many years. Very disappointed.

Wow! I am impressed! I put the phone separation on the quickest alert setting (1.) And it does not bother me at all and of course it has to be moving anyway. Its a short distance but I could have went shorter but its probably short enough. Definitely if leaving a phone. I would put 10 feet if could have lol.....no this separation alert is a game changer. I can't believe its one of the only ones on the market. Or at least Amazon, which basically is the only market. Anyway I am so very happy with my purchase. I am afraid if my mind is too busy and leave my phone then it is possibly too busy to hear the short beeps. But fortunately I found one sound tune to be exceptionally high volume. So thatvsells mevbuying more. And Easy to change and buy this type of battery. But 2 years is a long time. At any rate this is definitely seperb, outstanding and I cant see anyone not having at least one. Amazon prime Day is near and I have added a price alert for a lower price to buy another one and probably a few more as time goes by. But to the buyer you have got to try this and I cant emphasize This Enough! Good job @seller@

When you leave your phone behind, you’ve lost everything and this unit keeps me alert as to the distance of where my phone actually is. It’s been invaluable on several occasions. It’s easier to set up. It’s loud and it’s reliable.

I was going to return it but the longer I’ve owned it the more useful it got to the point I give it 5 stars. It’s very easy to turn it off which makes it even more useful.

Es hat mir nicht gefallen, weil keine deutsche Anleitung

This gadget still works even if not connected to Bluetooth; however, it has to be paired.

Very good 👍

The idea is great. That said, I bought it and tried it out. Reviews tell me it alerts you after around 20 feet. This was just about ok for me, 10 feet would have been better. However, trying it out , it only alerted me between 30 -40 feet. By the time I get the alert, walk back to my phone, it may not be there! especially if you are out of sight by turning corners. The alert cannot be made to be closer, I know this because I wrote to their support and received a very Kurt and abrupt reply. Basically, live with it. I have, returned as it is inadequate. I want something that alerts me after I walk away 6 - 10 feet, then I can turn around and pick it up in a few steps. If you want this, it's a great device. If you want something like I do, don't bother. 3 stars as it does alert you - at some point.
