Nulea 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.

Very comfortable to use with a smooth, accurate action. I've turned the sensitivity right down to make it easier to follow the pointer. Genuinely plug and play with no set up needed. My one comment is that I wish the forward and back buttons could the reversed, as the forward button, which I rarely use, is in the more natural position.

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.

Bought as a replacement for my 5 year old Logitech M570 Wireless Mouse Trackball which was getting a little glitchy. I love the bluetooth pairing which took all of 8 seconds and frees up a USB slot. Like the construction and feel, and at £10 less than the old one, I'm delighted. Recommended. By the way, although the manual says the back/forward buttons don't function on Mac OS - they do!

I purchased this as a replacement for my Logi trackerball mouse that had given up. I have had a couple of Logi ones before, but they just don't seem to last anymore and I am lucky to get 18months out of it before the bluetooth packs in.I bought this mouse as read the reviews which were mainly positive. In terms of comfort, it isn't quite as comfortable in terms of hand position as the logi, but I have quickly got used to it. I like the multiple connectivity options that comes with the mouse and hope that it outlasts previous logi mice I have owned. Only downside I would say is that it has a built in battery, so needs to be kept charged up. You can't charge it on a USB plug, only a computer USB or other low power charger, you also cannot use the mouse whilst it is charging. With it having a cable it would be helpful to be able to either use it as a wired mouse when connected, or to allow the device to be used whilst charging.

This is a good trackball mouse if you thinking of picking up a trackball mouse. The trackball is very smooth and accurate and once you get used to it, there is no reason to go back to normal mice. the ability to pair it with 2 bluetooth devices and 1 usb is really good and the charge lasts a long time. There are however 2 drawbacks with this mouse - first is that it could have been tilted more to make it more ergonomic, you will find your thumb straining after long periods of use. Second is that the left and right click buttons are a bit stiff. For an ergonomic mouse you would expect these to be more clicky and this sometimes leads to unclicked links or icons in daily use. Overall a good and cheaply priced trackball mouse if you are willing to overlook some of its shortcomings.

I've had many trackballs and this is a good one. Ball is smooth, button click is repeatable making it easy to use. Ball and the internal bearers need regular cleaning - as do other trackballs and mice. I sue the USB mode and it works well.

I had been experiencing some discomfort using a conventional mouse and gave this a go.Why did I not get one before? It's so easy to use. It's very responsive.You can connect using a dongle that fits into the base or two devices via bluetooth channels. You do this by advancing a push button on the base and holding it down to connect to the device you've selected. Battery life is great, I charged it when it arrived and it has not required a further charge since.Highly recommended for the price.

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

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.

Funciona muy bien. Para trabajos de precisión no es lo más indicado, pero para el uso diario del ordenador en oficina te evitas estar moviendo la mano con malas posturas. Se puede regular el DPI y la bola se puede extraer para limpiar sensores. Funciona con batería, tiene puerto de carga USB C y se puede cargar mientras se usa. Se conecta por bluetooth o por RF con un USB. Es muy completo y ergonómico.

Ottimo mouse, completo e funzionale.La prima carica è durata oltre 2 settimane utilizzandolo circa 8 ore al giorno.Sinora sono soddisfatto dell'acquisto.
