BALL NOT SMOOTH AS EXPECTED

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 Elecom P.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

Hi giving this a one as this is the second Elecom trackball I purchased that has failed inside of 6 months. Thought to save some money but with two units going down, I should spent the cash upfront for the Logitech instead

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.

For too long the only real option for a good thumb track ball mouse has been available from logitech and even they reduced their range over time, leaving just the wireless m570 as the only one. What is unfortunate is they also cheaped out on some of the components used too (probably due to lack of competition) which often causes them to develop a fault with the buttons/switches (often registering double clicks or not at all). It seems like a very common problem and more than just annoying! It makes them unusable! This is what happened to mine of course and repairing/fixing the issue meant having to replace the switches (too much hassle) or purchasing another, which again was likely to get the same fault after an unacceptable amount of time considering the price. For a long time I searched for alternatives but many seemed to suffer from poor design and other annoyances/lack of features. Finally I stumbled across this Elecom EX-G M-XT3DRBK (Careful of the stupid naming scheme, there are a few variants!) so order it, but thinking again, its likely it would not be what I had hoped. Thankfully I was totally wrong, its been excellent so far. Not only is it a good replacement from the m570, its better in just about every way. It has more buttons and functions and has not developed any fault even after continuous abuse. It also has a nicer feel than the m570, especially the finish quality and shape as well as the button clicks (specifically the back/forward). It makes the m570 feel cheap in comparison IMO. It has 3 buttons + scroller + scroller tilt clicks left/right/center as well as the normally back forward buttons, it also has a high and low speed switch (I use mostly high). All the functions work using the default plug and play drivers, except for 1 of the 3 main buttons, but using Elecoms own driver/software can over come this and also has the added benefit of assigning anything to any of the above functions, including gesture options! The only thing is misses is the precision option, but that can be selected in windows mouse option and you are good to go. Just search for ELECOM Mouse Assistant (global) to find the download. The only slight annoyance (cant call it a fault) I could find was the smoothness when new, but this seems to have improved with use and now feels much smoother than the m570 ever did. The name of the product is also a bit stupid, Elecom really need to sort out their naming scheme as its just confusing, still it does not take much away from the product itself, which I would not hesitate to highly recommend to any looking for good thumb tracker ball. I believe this to be the best thumb tracker ball currently available on the market.

Works well and convenient
