Nulea M501 Wireless Trackball Mouse, Rechargeable Ergonomic, Easy Thumb Control, Precise & Smooth Tracking, 3 Device Connection (Bluetooth or USB), Compatible for PC, Laptop, iPad, Mac, Windows.

As a long-time user of the old wired Logitech Trackman Wheel models, I was hesitant about trying this.I had bad experiences with TWO of Logitech's newer M570 models wearing out their buttons in less than 6 months time. I even bought used Trackman Wheel models online after they became discontinued, and those lasted a lot longer than the newer M570s.I've had this Nulea for 3 months now and use it daily, and can safely recommend it for anyone looking for an alternative. It has been reliable and works very well for someone used to the Logitech models.The position for your hands is ever-so-slightly different than the old Trackman Wheel's slope/angle, and it does take a few days to adjust if you're so used to another model. But it's very slight and not anything that feels drastically different. Once you've acclimated, it feels very natural and comfortable, even for all-day use.Just like with the Logitech models, it successfully keeps my wrists and hands pain-free, where with a normal mouse (which I gave up decades ago for this reason) I'd have bad hand cramps and wrist pain from the repetitive movements involved.Other reviewers have mentioned Nulea has great customer service, but so far I haven't had any need to confirm that myself. Everything is working great for me. I chose to use it via the wireless adapter rather than bluetooth, simply because my bluetooth connection is a bit spotty at times for my liking (with other devices too, not just this trackball) but it has been a great experience using the wireless USB adapter.For anyone who happens to use Linux, it works flawlessly on Linux Mint for me. The sleep mode is handy for those times when I forget to turn it off overnight, or just in general for idle periods to help conserve battery power. When it enters its sleep mode, all you do is click the left button once to wake it back up, and then you can move the mouse and use it like normal again.After the initial charging period when I first got the device, I've only had to charge it I think once or maybe twice, in a 3 month period, so the battery lasts for a long time on a charge.The DPI button is really helpful to have too, and I like to set it to the max amount. I was sorely missing this feature when I briefly went back to using my spare old Logitech Trackman Wheel on another device for a time. I'll probably order a second one of these Nulea models for that device at some point honestly, now that I know they are reliable and great to use.It might seem like a small thing too, but I also love that you can pick different color trackballs. I've got the gold model and really like how it looks with the dark grey.The only odd thing I have noticed so far is that the scroll wheel sometimes has a bit of a squeak or "chirp" to it after a while of using it (I thought it was a bird outside my window the first few times I heard it, until I realized) but it doesn't seem to impair functionality any, and most of the time it isn't an issue.Right now as I type this and scroll the wheel it's not making any such noises at all, for example. Even when it does squeak a bit, it's nothing that feels like it's faulty or in any danger of breaking. So far it is definitely not a problem, and my experience overall with this trackball continues to be a very positive one.

Great mouse. I like the feel and ease of use. Nulea claims that the battery will last about 10 hours and I'm way past 10 hours. So far I'm about 30 hours into using this mouse and it's still working great. Nulea is more affordable than Logitech but is just as good if not better.

This Trackball is almost perfect. It functions really well, I love the multiple connection options (BT1, BT2, RF) it has a built-in rechargeable battery and is ergonomic. It is very comfortable in use. It would be 5 stars if not for the one thing, the button to switch between the 2 BT modes and RF. It is too tall and should be recessed. The button in question is located on the bottom of the trackball. When I first started using it the trackball would stop working and I would cycle the power SW and it would work again. I eventually figured out the reason it was doing this is because I use it on my leg at my desk and so I would inadvertently bump the switch to another mode (BT2 or RF). I was able to fix it by taking the trackball apart and removing the button insert (the button is soldered on the pc board so you can still switch modes with a small piece of plastic). It now functions perfectly and I love it. I would recommend the manufacturer make a recessed button insert to make their trackball perfect. I will probably file down the insert and reinstall to make it recessed and not so easy to inadvertently switch modes.Overall a great trackball otherwise and I highly recommended.

I have been a longtime user of the Logitech Trackman series of thumb-operated trackballs since they came out in 1996 (the white ones) and have been using nothing else since. Sadly, they changed from the flatter white models to the more "humped" gray models which are not as comfortable but generally just as good.The problems with those gray ones is they are somewhat slippery and, as they are angled higher, your hand wants to slide off of them (solved by adding grip tape to the top) and the trackballs eventually get sticky and jittery leading to a jerky mouse movement no matter how well you clean the trackball or the bearings inside the housing and you have to buy a new one every few years.Instead of just buying another Logitech, I decided to try this Nulea model and I'm quite impressed with it. It too is quite slippery and could use some grip tape but it's slightly flatter and more comfortable. The trackball is very smooth (at least it is now while new) and the buttons seem to be adequately stiff so you don't accidentally activate them if you rest your fingers on the buttons.Like Logitech, the buttons are a bit narrow and my right ring finger sits more to the side of the right button rather than centered on top of it so sometimes I press and nothing happens since I'm not actually on the right button. That's a muscle memory issue I have to get used to (or rotate the mouse slightly clockwise so my fingers are more centered over the buttons.)The DPI button is good for when you need fine control - just click it to get back to the minimum value and do what you need to then click it to get back to the higher value. A nice touch. The scroll wheel turns nicely and is not too clicky. The forward/back buttons are nicely positioned and work well.The description says it's not compatible with FPS gaming but I tried it with some standard games such as Far Cry, Sniper Elite, etc. and it actually works totally fine. Using the DPI button as well as the built in mouse settings in Windows or a 3rd party tool like X-Mouse Button Control allows you to speed up or slow down the mouse to dial in what you need for aiming. I have no issues with it in gaming.So, brand new out of the box, I'm very impressed with the build quality and ergonomics of this trackball. It's not perfect but nothing ever really is. For the price, this is a fantastic value. Hopefully it lasts as long as my Logitech models did.

I like cordless, trackball mice and have had to be reliant on the Logitech brand. They USED to be wonderful, but switched to the cheapest micro switch maker they could find. Any other brand was worse. I had to swap for new ones every 18 months or so. They CAN be repaired, but it's a PITA to do.This new brand was a good price. It's well made, nice ergonomics, more button options then Logitech and best of all - recharges via USB. This kicks ass over swapping AAA batteries a lot on the Logitech.I love it. It's wonderful to use. I will never buy another Logitech product again - my keyboard is now a superior Razer.You will enjoy this mouse. It also came with PRINTED instructions! Yay!

Es un mouse muy bueno, quizá un poco incómodo al principio pero te acostumbras al paso del tiempo. La batería dura muchísimo. Muy recomendable

Was snel kapot. Werkt niet lekker. Niet te vergelijken met een Logitec trackball

I have used a track ball for years (I prefer one to a mouse as they work better in a confined space being static) but my old wired Genius wired version was losing smoothness despite regular cleaning.After first looking at Logitech as one of the main brands I spotted this Nulea Trackball and after reading the reviews decided to get one after considering the cost, Bluetooth connectivity and that it is also rechargeable.So far I have not been disappointed! It is extremely smooth in operation and easily paired using Bluetooth (there are two Bluetooth version options - v3 & v5) as well as a 2.4ghz wireless dongle (stored on the underside of the case) as per typical wireless Trackballs and other peripheral UIDs. It can also be connected using the supplied USB USB 'A' to 'C' cable included in the box that is used for charging it - the USB 'C' port being located on the front of the Trackball.The required interface type can be selected with a 'mode' button on the underside of the unit next to the power on / off button. I was particularly looking for Bluetooth connectivity as it saves the need to use a wireless dongle which can easily be lost or broken. Having 3 connectivity options with this device makes it very versatile.The case has a non-slip rubberised feel to your hand is less likely to slip off it in use or when moving it about - especially if using it with multiple pieces of kit. There are the usual left and right buttons and scroll wheel / button in the centre as well as the page up / down buttons to the left of the left 'mouse' button. There is also a small DPI adjustment button below the scroll wheel that can be adjusted to preference.There is an LED below the DPI button which indicates the battery status when charging (Blue) or when the battery becomes low (Red).So far I am very impressed with this Trackball considering it's a brand I'd never heard of. The only thing that concerns me is that I've owned numerous things that have been made with a similar non-slip coating (Sat Nav, Binoculars etc. etc.) and after a number of years the coating has perished and turned into a very sticky unusable condition. Only time will tell but I would certainly recommend this to anyone looking for a good quality, wireless Trackball.
