Ergonomic Mouse, Vertical Wireless Mouse-Ulytech Rechargeable 2.4GHz Optical Wireless Mouse: 3 Adjustable DPI 1000/1200/1600 Levels 6 Buttons, for Laptop, PC, Computer, Desktop, Notebook etc.

First thing’s first, the speed adjustment, really does not do much so if you game, so you would have to change some of the mouse sensitivity settings in the game options. That is truly the only negative comment I have on this product. It. Is. Great. Phenomenal even.The design of this mouse is something I am a huge fan of. The vertical mouse shark fin design fits perfectly and comfortably in my hand. I am not a fan of wireless mice but jeez I love this mouse so much I will make an exception. It is rechargeable so you do not have to worry about changing batteries, plus it has a stand-by mode so it does not use up all the power. I honestly do not know how long it takes for these batteries to die since I have kept this thing on for 2 days straight now and it still works. I seriously could not wait until it died to write this review because as far as I can tell this thing is immortal, I know it isn’t but still the batteries haven’t died!Do I think it is worth this price? Well, at the time of purchase this Vertical Mouse was $14.99 . My simple answer is...YES get this product! It is a mouse that is both energy efficient and comfortable to use. Again, if you want a more sensitive mouse then you gotta change the settings on the computer itself.

Battery life is good

Love the mouse and got lots of compliments from co-workers. They all tried it and said they would order one.

it could have been better if a little bit smaller

This mouse works well. It is simple to use and the various features work well. The wheel works well without sticking and it has subtle clicks when you roll it. The wheel does not have side to side functionality. The DPI button is great to have, but it is located in a bit of a cumbersome location which could slow you down if you wanted to adjust the DPI rapidly (e.g. gaming). The main right and left mouse buttons don't have very good clicks. The back and forward buttons (on the side where the thumb goes) are very well placed and click great. The battery seems good and the location of the charging port makes it seem like a regular wired mouse when plugged in (i.e. the charging cable plugs in on the front of the mouse, not the back or bottom which I've seen on other mice). Overall, it is a great mouse but the construction seems a little bit cheap. It is still excellent quality for the price though.

I bought this when I needed a vertical mouse but didn't want to pay the full $20 for Anker's mouse and I thought this was basically the same thing but is now rechargeable. For the most part, it gets everything right, it felt a tad smaller than Anker's initially but that didn't bother me too much. I ended up returning it because there was almost no tactile feedback with the mouse buttons. the left and right mouse buttons were SUPER mushy and as someone who works a lot on his computer, it's nice to feel and hear whenever you make that click. Everythign else about the mouse was fine, just wish they payed more attention to the button.

But, the alignment of the buttons leaves something to be desired, such that the 'left' (upper) button is difficult to activate and the lower button sticks. This is because the plastic button plate is not upon equidistancely. I also have the Anker version which does not exhibit this condition. The folks at Ulytech were delightful in sending me a replacement, which, although it suffers from the same misalignment, does behave better, so I'm using it successfully. All that said, you cannot beat the price and the service and the rechargeable batteries, so I recommend this mouse.

I now have two of these which ought to say a lot. Very comfortable and easy to use. I definitely prefer a vertical mouse, and the fact that this new one is rechargeable is an extra plus. The only slight negative is that these mice are taller and it can be easy when moving around to hit the top of the mouse with hand or arm and knock it over or even onto the floor. A little carefulness can reduce most of such incidents, though ... so not a big problem. I recommend this mouse very highly.
