Delux Wireless Ergonomic Vertical Mouse - 2.4G with USB Receiver, Silent Clicks, 1600 DPI, 6 Buttons, Removable Wrist Rest, for Laptop PC (M618Plus Wireless-Black)

Works just like my old one. Looks just like it too! Just what I wanted .

* REAL ergonomic mouse, for large hands* Reasonably priced* replaceable battery, so not throw awayCAVEAT: I'm no gamer but I don't think it's a gaming mouse. I don't think any vertical mouse is though.This mouse has been perfect for me and it's not my first Delux mouse. Hand size is extremely important when trying to buy and ergonomic mouse even though few reviews actually talk about that. Now, "ergonomic" is more a marketing term for some mice but this actually is. I love it having the "old fashioned" battery because as it is, it's not a throw away product the way more expensive ergonomic mice are. I know that lithium is supposed to last, but they don't in many mice, and the charging port can/will become unusable (it's just a race for which goes out first)

My mouse died so I had to look for a new one. IT has been ages since I shopped for a mouse and this new ergonomic style looked to have some advantages over traditional mice. So lets get into it.I work on a computer all day 8-16 hours a day depending upon demand. I do not game much. I have been having trouble with Tennis elbow over the last couple months, no idea why as work habits an life have not altered. I thought the ergonomic mouse might help because of the change in wrist/hand angle. I only got it an hour ago so I have no info on whether it will actually help that but it is comfortable. Now for the details.My hand is 7.5" long. Using a more snug, not tight, grip with my palm resting firmly on the body of the mouse, my ring finger extends about 0.25" beyond the LED line around the body while my thumb has 0.375" extra space beyond the end.I like the thumb button placement being 1 above and 1 below. That allows for slight movement to activate the buttons.The main button placement is good. I have medium width fingers and can operate the buttons with either index and second finger or index and ring finger depending upon how I rest my palm in the grip space.The roller button is responsive and works well with a slight detent feel as it rolls. However, it is a bit of a miss in terms of ergonomics. It is too close to the palm to use the middle finger on the roller when gripping the mouse closer. I have to either clench raise my hand slightly off or to the rear of the mouse or clench my middle finger to get to it. Neither of those is ergonomic. Rotating the body of the mouse and thus adjusting the relative positioning in the hand, allows using the first two fingers for the button and more efficient use of the index finger to use the roller. (It would be really nice to have that roller father forward away from the wrist allowing better usability for the middle finger. Then I could engage all three fingers simultaneously...While the ergonomic shape is nice for releasing tension in the forearm, the one thing that is very different is the movement to and from the keyboard. on a traditional mouse the user barely needs to raise the wrist to move across the mouse to type. the forearm can stay on he desktop. The significantly increased height makes a much larger gross motor movement to get to and from the keyboard. I am not sure I like that. It is a very different movement so it will take come time to get used to.The DPI selection is very nice allowing the users who want faster movement and more sensitivity to get it. The instructions indicate that it will go up to 12800 and the cursor zooms.While the mouse works out of the box, some of the features require the driver to be downloaded from their site and installed. Installation requires admin level access.

So far it seems to be a great mouse! It is very comfortable to use.

Bought this mouse because I started to notice some discomfort in the right wrist and hand when using the computer for a prolonged amount of time. I figured that not only would turning your mouse hand a bit more sideways help ease pressure off of your carpal tunnel (which will in term lead to tingling, numbness and pain), but it'd also alleviate muscle strain from having to have your forearm fully pronated (palm down).I have now been using this mouse for a few weeks and feel that while it helps in one way, it hinders you in another way.Yes. It feels more natural (at least to me) to rest your hand on the hypothenar mass (the meaty side of the palm of your hand by your pinky) while at a desk and operating mouse. However, I feel that operating the mouse with your hand in this position sort of decreases your accuracy with the cursor on screen.Discomfort trade off. I truly believe this mouse will deter Carpal Tunnel Syndrome. You will no longer be putting pressure directly on this structure. Nevertheless, you will be putting pressure on something. In this case, you will start feeling discomfort on the Triquetrum (A small bone in your hand just distal to your wrist); as this will become the atlas of all your hand movements while operating this mouse.The mouse comes with an attachment that I found hindering rather than helpful. This additional pad (made of hard plastic) forces you to lift your arm more than you should in order to push, drag and glide the mouse in order to move the cursor to where you need it to be; resulting in shoulder fatigue.I really wanted to love this product, but even with the aid of a large mouse pad, I am still feeling some discomfort.Aside from the ergonomic review, the mouse functions well.All in all not a bad product, but not as great as I was hoping.

Easy and inexpensive
