excellent item.

Desde el principio superó mis expectativas.Se comunica sin interrupciones y funciona a la perfección.

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.

I have been using this trackball since Jan 6, 2024, and so far this is the best trackball I have ever used. It seems to be a better build quality than Logitech, which I have always had. This is the first time I purchased a different brand and I could not be happier. You can adjust the movement with the push of a button on the top of the trackball, very nice. I connected mine via Bluetooth and it connected almost instantly when I turned it on for the first time. Very easy to connect and set up. It goes into sleep mode after about 15 minutes, but you simply touch one of the buttons and it is awake and ready to use in about 1 second, if not less. I liked it so much that I got one for my wife and after her first couple days of using it, she loves it as well. I cannot comment on longevity and I will update if anything further. At this time I would highly recommend this trackball.

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.
