NuleaM501 Wireless Trackball Mouse, Rechargeable Ergonomic, Easy Thumb Control, Precise & Smooth Tracking, 3 Device Connection (Bluetooth or USB Receiver), Compatible for PC, Laptop, Mac, Windows.

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 picked up this trackball specifically because I didn't have the room to use a mouse.What I like:+ Rechargeable battery.+ only need a space as big as my palm, your thumb does all the work!+ Multiple Bluetooth connectivity, I can connect to multiple computers, or use the included dongle if required.What I don't like: Nothing yet.Recommendation: Yes; I would recommend, it is cheaper than the name brands and works quite well.

I've been a fan of thumb trackballs since the Logitech Trackman in the mid '90s. I've tried other non-Logitech trackballs. This is better than anything else out there - including the current Logitech offerings. The ball sits solidly in place and doesn't shift around like some trackballs - even if you're using it on an inclined surface like the arm of a recliner.The device feels solid and the large grips hold it in place on a desk. I love that there's more than one color option for the ball.*** Most importantly *** this device is not limited to a single Bluetooth connection but can connect to two devices via Bluetooth and a third via the USB receiver. I like that the selection button is on the bottom of the device where it can't be accidentally bumped and that there's an individual LED for each connection rather than a single LED that blinks out which device is connected/connecting.My only wish for this is (and the reason I didn't give 5 stars) is - why stop at 2 Bluetooth connections? The sweet spot to me would seem to be 3 devices: work computer, home computer, tablet. Yes, this device does support 3 connections, but only with the USB receiver. Many laptops are dropping large format USB connectors. For me, that means I can really only use this with 2 devices.One minor nit: The USB receiver is nicely recessed to prevent accidental dislodgement, but it's so well protected that only smaller fingers - or fingers with long nails will be able to easily extract it. This isn't an issue for me as I don't intend to use the USB receiver, but might be for some.

Got this instead of another unit costing much more. It connected with Bluetooth easily and works fine. A minor gripe: it shuts off after 30 minutes, and has to be restarted, which can be annoying, but not a deal breaker.

He comprado otros trackball de marcas conocidas (y más caras) y éste hasta el momento va tan bien como esos. Espero que sea duradero, los otros más caros al año o antes empiezan a fallar.

I have had several Logitech track balls. One was a hundred dollar mouse. They all worked just as well as this less costly one, with a difference; this one has Bluetooth connection. Being able to use Bluetooth means I do not need to use up another USB port.The mouse responds well. I can adjust the cursor speed if I want.The shape is very comfortable, although I would have enjoyed a little more rubber on it to make it more comfortable, and more resistant to hand oils and sweat.The ball moves well, but like all other track balls, dust and dirt easily and quickly build up on the inside, slowing down the ball and affecting the cursor. Yes, it is simple to clean, but I would love some sort of a brush system somewhere to help clean the ball as it is being used.

Since the mid 80's, I've had several Tracker Ball Mice and as an 80 year old, I can honestly say that this is the best Tracker Ball Mouse. It doesn't go into sleep mode until it hasn't moved for 30 mins, others I have used sleep mode within minutes! I charged up the internal battery with the included "c" to USB cable - a decent length instead of the usual 2inch or so cable, they've got that right as well. It was easy to set up after I downloaded a big print M501 manual from Nulea.com. It paired quickly with my Desk Top Dell i5 Core running Windows 10 Pro. without having to use the included Nulea USB dongle. It was simple to go through the DPI range to alter tracker speed. Considering the price, and comparing it with a mouse I have that cost twice the price - it is more user friendly and easier to set up. All I have to do now is set it up for my Assus VivoBook 17 Laptop running Windows 11 and register the warranty, (that other makes don't include). Now when I change machines, I won't need to swap out the dongle. As my daughter's birthday is coming up soon, I'm going to get one for her as she always wants to borrow my Tracker Ball. Can't fault it - it's great!

5 stelle, Amazon davvero impeccabile nella consegna. Il prodotto è di ottima fattura e si presenta anche molto bello da vedere, nero opaco e con una superficie satinata. Un mouse davvero ergonomico che permette alla mano di assumere una posizione naturale e senza torsioni tendinee particolari. Sono tanti i tasti funzione necessari e tutti a portata di dita. Il trackball si rivela estremamente scorrevole e preciso con la possibilità di calibrare lo scorrimento della freccia di selezione sullo schermo. Il mouse è dotato di una batteria ricaricabile con cavetto Tipe C a 5V, compreso nella confezione che rende il prodotto moderno e senza necessità di acquistare pile 1,5V che rappresentano una spesa ulteriore. Nella confezione è compreso anche un comodo cuscinetto per appoggiare il polso. Ci ho lavorato solo 9 ore ma l'indolenzimento al polso che normalmente si presentava oggi non c'è. Consiglio a tutti di comprare questo prodotto perché la cura costruttiva, nei particolari e nell'assistenza di vendita merita davvero 5 stelle.

J'avais eu un trackball d'un autre marque il y a quelques années et il était tombé en panne.Depuis je me satisfaisait de souris classiques, mais quel plaisir de revenir au trackball.Tellement plus ergonomique, pas de mouvement du bras, réglé sur la vitesse maximum, c'est beaucoup plus rapide, précis et réactif qu'une souris, le curseur réagit au plus petit mouvement du pouce, je l'utilise même pour jouer aux FPS.Je prends souvent le train ou l'avion et c'est vraiment plus pratique qu'une souris.Enfin la possibilité de le lier à trois périphériques différents (le récepteur USB + 2 Bluetooth) me permet de l'utiliser aussi bien sur mon PC de bureau que mes deux portables.Le fait qu'il soit sans-fil et équipé d'une batterie rechargeable par USB est également un gros plus par rapport à la concurrence qui utilise des piles (piles que bien entendu vous n'aurais pas sous la main quand elle tomberont en panne...).Si vous n'avez jamais utilisé de trackball, il vous faudra quelques heures pour vous y faire, mais une fois acclimaté, difficile de revenir en arrière. Pour ma part et même si j'ai mis presque 3 ans pour en racheter un après que le mien soit tombé en panne, je n'ai jamais pu me réhabituer au souris et j'ai toujours regretté mon trackball.
