Delux M618 Plus Ergonomic Vertical Mouse Wireless Optical Mouse 1600 DPI

I've had this mouse for about 2 months and it has worked great.... Until today! Today, the back button decided to open my media instead of being my back button. Tried downloading the driver again and actually found the configuration tool, which I had never seen because there are basically NO directions beyond how to insert a battery. But no matter how many times I tried to set the back button to actually go back, every time I click it, my default media opens. I have no idea how this has happened since, as stated, I didn't have the option to configure the buttons before I updated the driver today. Had an evoluent before this one and it lasted several years, but thought I would try and save some money, plus I love the plate that your wrist sets on instead of always dragging it across the mousepad. But I need it to work.

I had surgery on my bicep and am currently recovering, bc of that I can not turn my wrist and use a normal mouse. This has been a great product that has allowed me to go back to work sooner and be more productive rather than trying to use my left (non-dominant) hand with my regular mouse. It does take a little getting used to using but I have now been using it for a couple weeks and it is much more comfortable than a regular mouse on your hand and wrist. One downside is the size of it compared to other mice, it is big, and at my job I go from meeting to meeting so it is somewhat of a pain to carry. Overall still very happy with it.

Not sure if I can use this mouse. The scroll wheel alternates from being too slow to being too fast. It either moves every other line per click or jumps half the page down with a single click. I can't find any instructions anywhere on how to configure the settings. I've tried changing the speed of the mouse under my computer settings but that hasn't helped.

This mouse is outstanding! Responsive and easily the most comfortable I have ever used. If you use a mouse every day you can't go wrong with this one! We have a cheaper one and I use some track balls at work, and have had a few gamin mice and a ligitech mice. This mouse is more comfortable than any of them, it has nice tactile feedback on the buttons and overall just looks great.

This vertical mouse is literally just what the doctor ordered! Several fingers on my right hand have limited mobility making a traditional mouse difficult to use. This ergonomic mouse improves the position of my hand which makes it easier to hold and control the functions of the mouse. Great product!

I think this was a worthwhile but I'm faster with a regular mouse. I work on my laptop a lot and time is a factor. By the end of the week my hand kinda hurts and switching to this mouse definitely helps.

This device provides great relief for my wrist ailment. I had an ulnar nerve issue and this has helped to relieve that pressure. I have bought a few of these as I've time, due to travel, I have broken a few.

I like everything about this mouse except the thumb buttons. It get's inadvertently hit a lot. For my work, accidentally hitting the back button on the mouse is critical. I downloaded software to disable the thumb buttons so this is a pretty good mouse.

When this mouse works it is great, much better for the wrist than a normal mouse. However the mouse sensor seems to struggle on some surfaces including my work desk which my other mouse handles fine. Would give 5 stars if I did not have the sensor problem and while it is fine some of the time this is of course the core function of a mouse so 3 stars it is. ( If did the mouse pointer is not moving smoothly I suggest using a mouse pad)
