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

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.

Good quality works well works via a dongle comfortable as your not moving your arm around. I tend to use this for productivity task rather than gaming though id say it would work great on point and click titles. Weight isn't much of an issue as you don't move it around like a mouse though you may need bigger hands for the design. It's cheap enough to give trackball mice a go but decent enough that you will likely not change to another model. No silent click nonsense like the Logitech so you actually get feedback when you click.

I bought this with 2 other trackballs to pick one to replace my Logi M570. I have to say the build quality was superb. the overall feel was a little bulkier in my hand than the M570 but they are very close, buttons as well. The trackball itself was smooth and precise, even though it is a tad smaller than the logi one, they are not interchangeable. The only thing that put me off was the finish, which I found, in the hand, was very slippy. It felt nice to touch and looked nice, but was too slippy to use resting my hand on it. Other than that a fine trackball that stuck to the table admirably when in use. I did return this item, in favour of one of the others.

I bought this because I am using a very small desk at the moment and using a normal mouse is uncomfortable! This is the first time I’ve ever used a track ball mouse and I have to say I am now a massive fan. It is crazy smooth., easy to use and connected without any issue the quality is amazing as I said the track boy is the smallest thing I’ve ever used and with the fact that it is Bluetooth and USB connected it makes life so much easier!

Very comfortable and responsive.

An excellent addition to a crowded desk. Takes a little time to get the hang of it, but it works a treat.

Best mouse I ever had. Needs very little space on the desk, doesn't need to be moved at all and can be used on the lap. Also it's rechargeable via USB straight from the laptop even when in use. One charge last like forever. The easily accessible button underneath lets you switch between three PCs. The angle of the buttons and wheel is just right for me. The ball speed is also adjustable between pathetic and where-the-hell-did-that-cursor-go-?.

1. On pressing down left click, pointer often moves to right - shouldn't happen with a trackball. 2. Rechargeable facility is a pain because there's no indication of low battery - mouse just stops responding and you have to wait until charged - need an alternative mouse/trackball that uses replaceable batteries. 3. Life is easier now I've gone back to Logitech as none of the above issues now apply.
