What an awesome mouse! The shape is fantastic, dare I say, perfect. The build quality is great, it is sturdy and the quality of plastic, buttons, everything, is high. This is not a cheap, flimsy product. I love the multi-device connectivity; it supports two Bluetooth devices, 2.4G connect with an included USB dongle, and a wired Type-C connection. I use it through Bluetooth; which works really well and seamlessly. I love quickly switching between my PC and my work PC with a click on a button (located on the bottom). The mouse supporting two Bluetooth devices is a game-changer for me. The USB connection opening is wide enough where I can use magnetic USB charging tips, making charging the mouse much more convenient. The mouse is light and I like that it has a port where you can store the 2.4G adapter, so you don't lose it. Tracking is excellent on every surface that I've tried. Battery life is long enough where it does not annoy you. What's great about the G3 mice is that whatever you configure or program into them with their software, is remembered on the mouse. If you set a button to perform some action or a shortcut and you switch your mouse to another PC, it will still perform that action or a shortcut. Now, for cons, I also have a 800mAh G3 and I noticed that the Ultra takes more time to wake up from sleep, it is noticeable in every day use. I am not a pro gamer so I don't notice any difference between the sensors with the Ultra and the 800mAh, I use 1100DPI on both, so the Ultra is probably an overkill for me. The software is a confusion because the 800mAh uses a different software, and the Ultra uses a different software, although the software itself is fine and very customizable. On a personal note, I wish the mice used a AAA battery, I would sacrifice some weight for it. Having a built in battery is not great for long term storage. Finally, MCHOSE themselves are great! Very responsive, the order was shipped quickly and everything was fine. I highly recommend MCHOSE and the G3 mice!

Great value, good quality product. Perfect replacement for my G305.

Me encantó el diseño, definitivamente pienso usar este ratón hasta que muera definitivamente. Se siente una calidad superior al g203 que usaba y mayor ligereza a la hora de usarlo, el envío fue relativamente rápido y el paquetado un 10/10 muy bien protegido

Best value mouse contender. That is all really.

Can't imagine buying some overly popular and overrated mouse for 150+ euros/USD (cough cough Razer/Logitech). This mouse might straight up outdo it, it for sure will regarding value for money.

Side buttons could maybe be a bit better, but its all personal preference really, they all work perfectly fine and are of good quality.

It is smooth, light, fast, pretty and good built for a reasonable price. My only issue is that the first two dpi levels are colored the same as battery indicators and I haven't found a way to change the colours. I have no need in changing my dpi on the fly, but I can't leave only one level, because I will mistake it for my battery indicator. Other than that everything perfect. (Ok, I maybe a little tiny bit miss my lighting when trying to find my mouse in my pitch dark room, but it is not a big problem)
