BALL NOT SMOOTH AS EXPECTED

OK my mouse broke after 3years ish a jelly trackball. So I saw this on black friday deal. I've had logi also. This mouse is hands down way better. The software works well. The 3rd click on the mouse is just brilliant for fast opening of certain things my computer etc. If you like trackball mice this is a great deal right now. Speed is nippy with on the fly high or low. Then in software you can change cursor speed etc. Ohhh and it's super comfy. Even if you have larger hands I think this would still be awesome. I don't do many reviews unless it's something really worth talking about. So yea if you want a trackball you've found it..

The mouse is good and all the buttons work nicely with decent options on the customization app, however the track ball although is working fine it's not fully firm in it's position and slightly loosely fitted in it's placeIt might not be a big deal but I hoped that it was designed to be more firm in it's socket for easy and accurate tracking

I've been using this trackball for a while now. I absolutely love it. It's nice: heavy and sturdy. Beautiful really! Just what I expected from Japanese technology.

Viniendo de dos Logitech M570 seguidos, con sus habituales fallos en los botones, el cambio ha sido muy facil, Es ligerisimamente mas corto que el M570 pero muy comodo y manejable. Practicamente no hay diferencia en la postura de la mano respecto al Logitech. Muy utiles los botones adicionales. La precision es mejorable. En ese sentido daria un 10 al M570 y un 8 al ElecomP.d.: añado que le he puesto la bola del Logitech y la precision es ahora absoluta. Parece que el dibujo de la trama de la bola Logitech funciona mejor

Bought this as the switches in my 1st generation Elecom wireless trackball (M-XT1DRBK) started playing up. It was far easier to buy a new mouse, and I'm damn glad I did.The external design hasn't changed from Gen1 - they physically look identical - save for the forward and back buttons, which are now of a lower profile. This is a good thing - it was a fantastic thing to hold in the first place.Popping the trackball out reveals the artificial ruby bearings, which are much larger than the ceramic ones previously used. Having only used it for a day I can say that the movement is more positive, albeit a bit scratchier. A bit of PTFE on the bearings might fix that. No comment on maintenance intervals yet as I haven't had it for long enough - Gen1 lasted about a week or so before needing cleaning so I expect this to last longer.The two biggest changes in terms of feel are the switches for left/right click, and the scroll wheel - these are the reasons I'm glad I upgraded.The switches weight are perfect, being a little on the heavy side, with a loud and tactile engagement. Blows Gen1 out of the water in this aspect, even when they did work properly.The second change - the scroll wheel - is minor but makes a huge difference. Since the first day I got the Gen1 trackball the scroll wheel always drove me up the wall, as the scroll wheel had a lot of play; it would move up and down whilst scrolling, and when clicking it would move forwards, and therefore never delivered consistent performance or positive feedback. The new scroll wheel is much better though, despite the wheel itself not changing.Overall this is a great option for a thumb trackball, and is very reasonably priced for what you get. Better than previous generations AND the M570. The Logitech MX Ergo would have to deliver unbelievable performance to top this.
