MOJO Master Grip Rechargeable Silent Vertical Mouse - Bluetooth/Wireless Ergonomic Mouse w/Adjustable Sensitivity and Quiet Buttons, Custom Software

I'm disabled and unable to rotate my right hand, so a mouse that is upright is so much easier and more comfortable for me to use. That being said I would assume it's this comfortable for everyone because my hand is stuck in the natural resting position, And it is so ergonomic, it feels like it was made for my hand. It has seven buttons including the mouse wheel, That I hotkey for gaming. It is truly bluetooth, no dongles required, although one is included and is stored inside the bottom of the mouse, I guess that's if you don't have bluetooth. And the bluetooth itself works great! I have never had the mouse disconnect or lag on me. And lastly the battery on this thing lasts forever. Whenever it comes time to charge the mouse I can never remember the last time I charged it, that's how long this thing lasts on one charge. I love this mouse and It has changed gaming for me!

Left mouse button squeaking and has hard stop in between clicks due to the plastic wearing out after 1 month of use. Do not recommend. ***Update. This mouse has stopped connectivity with its USB dongle after 5 months.

The good parts: - Good ergonomic shape - Buttons are very silent - Multidevice operation working great - Buttons for the thumb The usual aspects: - Mouse wheel is of so-so quality. Could have been better. - Of the four thumb buttons, only two are programmable, the two horizontally placed. These being far apart, the one of the left is inconvenient to use. The bottom button is for switching light modes. I often end up pressing it accidently, and then need to make 5-6 more clicks cycling through various modes to turn it back off. The ring of buttons should have been made smaller, and the buttons all made programmable.

I purchased two of these. I love this mouse, it is fuller and fills out the hand in a more relaxed state. This product has a lot of potential. I have issues with connection like others have mentioned and I thought one was breaking so I bought another after about 8 months of everyday use. It began to drop connection after 3 weeks. I have tried wireless, bluetooth, and leaving it plugged in but that does not help. If a wired version were to exist with better DPI control then it would be the perfect mouse.

The MJ-240 is absolutely terrible. While the form factor is great it doesn't stay connected and the interface and indicators are terrible. Here's an alternative that is much better: seenda Ergonomic Mouse, Wireless Vertical Mouse - Rechargeable Optical Mice for Multi-Purpose (Bluetooth 5.0 + Bluetooth 3.0 + USB Connection) Compatible Apple Mac and Windows Computers - Black

I thought this was a track ball mouse, it is not but it's quiet and quick and can use blue tooth and does need charged once and a while but it lasts days and can use a phone charger for it

The buttons are hard to push and some times do not accept the push.

This mouse is very comfortable. I have slightly smaller than average hands and this fits great. The battery life is good, I wish there was an easier way to check the level though without having to use Bluetooth. My biggest complaint is that the left click is pretty squeaky. That might be something I can fix myself but I can't really see how to take the mouse apart without breaking it. Update September 2024: The scroll wheel started to give out on me a few months ago. The mouse still worked, but when I would scroll, sometimes it wouldn't register and other times it would scroll the wrong way. I could still use it, but scrolling was incredibly challenging. I ended up buying the higher end Logitech ergo mouse to replace this one, but I feel that two years of use for this price is reasonable. Just know what you are going to get if you buy this mouse.
