Love there's has AC or DC plug in options so works great in my rv as well as jeep Keeps boots dry and warm

Bought these mid season to help with drying out my boots overnight. As a race coach I really wanted to make sure I had dry boots and these worked great. Dries pretty quick, seem to have good airflow, and relatively very quiet. I haven’t used the car yet but the adaptor for that is a great option.So far, impressed for a decent price point.

These dryers have been life changing for my ski trips. I use them to not only to dry my boots and gloves after skiing but also to heat them up before I get on the hill, making the initial gearing up "suffering" just that bit more comfortable.The good:- Works as expected, does both heat and air. Can warm up your boots within a couple minutes and dry them as well if left for a while- Shape works for both gloves and boots, very sleek- Comes with 12V plug so it works perfectly when parked at the lifts. Note that this also works in my 16V Tesla, not sure if it'll lower the life span but hey it worksThe not so good- Not really a "not so good" but a bonus would have been to include a carrying bag given the price. I reused a cinch bag from a pair of shoes to carry them but an included bag would've been an added value

I've only used this once, but it seems to warm up the boots thoroughly.

I’ve been using these boot dryers for 2 weeks. They do a good job at drying my ski boots and warming them up. I like that it gives the option to be 12v cigarette lighter or 120v AC. I can start drying the boots in the car when done or keep them warm driving to the mountain. The units are quiet as well

I bought these for a snowboard trip. Put them in my boots and it takes about ten minutes for them to get warm. The amount of air flow coming out of these you would have to have them on all night if your boots are wet in the inside.

I was a little nervous about these at first but I’m impressed with the fans in these. They dry out my wet boots overnight and are also great to warm them up if I need to go to work and leave my boots out in the car during the day. The one thing I will say is you should always make sure the car outlet’s adapter light is on indicating the male end is all the way in the female end. I have missed this before because it wasn’t completely in so the dryer didn’t work. I’ll chalk that up to user error though, this is a good product in my book

So the particular unit I received may or may not be defective. Some people say they work great but others like myself find it somewhat lacking.I like the portable idea using the 12v in a car & optional wall use is good. In my opinion & use case usb-c powered would be better. Certain power-banks I have could easily throw wattage into this dryer.Drying time varies of course. I left them in a pair of slightly damp boots for about 6 hours & seemed to be dry enough. This is when weather was in the 70’s.On a camping trip when it was still fairly chilly out & lots of rain it took 8+ hours to dry. Depending on how wet my boots were. I tried to dry them any chance I was back at camp.The heating element in my unit didn’t seem overly strong. Like mildly warm air was coming out, not hot. Even after a few hours of use not very warm.The small fan seemed to be doing alright though, decent airflow. Noise wasn’t a huge issue more like a very low power fan hum.Personally I was very underwhelmed when using the dryer but for damp shoes they’ll work. Just don’t expect large format boot dryer power from these little dryers. Like I mentioned though it could have been a defect in my unit, but either way this was my experience.I’d recommend giving them a try they might work for your needs. Just check the return policy just in case. Good luck
