Comanro Human Ergonomic Ev Mouse 2.4g Laser Wireless 6 button Vertical Ergonomic Mouse - DPI 500/1000/1800/2500 adjustable

Overall, a good product. The mouse is comfortable, buttons are easy to reach and all have smooth action. The only button that bothers me a little bit is the back/forward button at the base of the chrome thumb panel. I have irregular-sized hands. My palms are large, and my thumb is a normal size, but my index, middle, ring, and pinky fingers are somewhat shorter than they should be for a hand that has a palm and thumb as big as mine. So when I want to hit the back button on this button cluster, I have to pull my thumb back to an uncomfortable angle to trigger it, which causes me to have to lift my fingers and palm off of most of the mouse. I am not docking any stars for this because I can't imagine that everyone would have this problem, as this is mostly related to the odd proportions of my hands, but I figured it was worth mentioning.There are four DPI settings on the unit that can be changed on-the-fly by clicking a thin, transversally-situated chrome button at the base of the right and left mouse buttons. This is well-designed and I very rarely trigger this button by accident, if I have ever done so.The scroll button has a nice, smooth action and is very easy to operate.There are two power-on options for the unit. One which simply turns the mouse on, and another, which turns the mouse on and activates the light on the side, directly below the chrome thumb panel. I have noticed no difference in the operation of the mouse between these two power settings, of course, other than the light being on and changing colors every few seconds. It should be noted that the setting to keep the side light on will likely wear down on the battery faster than not having that light on.The mouse comes in a nice hard box and includes a foam place holder to keep the mouse in place when it is in the box, a quick-start booklet, and a charging cable - USB to mini-usb - with a velcro strap for easy coiling and storage. The mouse is plug-and-play, out of the box. The mouse holds a charge for an exorbitantly long amount of time; I have had the device for about three months, and only needed to charge it for about two hours once. It had a charge out of the box that lasted almost a month with daily operation. I have used it slightly less, interchanging with another mouse intermittently since then, so it might be something more in the range of needing a charge once a month. Still, very limited amount of charging needed to operate this unit, which is a huge plus.Build quality is good, but it unfortunately did not live up to my expectations for an $84 mouse. The chrome metal pieces of this mouse are rock-solid, and the black frame feels nice, but the dark blue components feel kind of cheesy at times. I also noticed that the switch on the bottom just doesn't look or feel very high-quality. The power switches on $30 logitech mice I have used in the past were of a higher quality. Overall, it's a high quality product, but the price point that I paid was a bit high for the build quality I ended up getting.To add to the concerns about build quality, this is a light mouse. The listing gives you a shipping weight of 10.4 ounces, but no product-specific weight in the item listing (if anyone finds this, please respond to this post with a correction; I was unable to find it listed anywhere). I was expecting a much heavier mouse, but was floored by how light this unit actually is in real life. Just be aware of this if you are expecting a heavier mouse. This, in general, does not take away or hinder the performance of the mouse in any way.Performance is unmatched for an ergonomic mouse. I prefer high-DPI settings, and sometimes like to change the sensitivity based on what I am doing. As stated earlier, changing the DPI setting on the unit is a cinch and can be done easily on the fly. The unit will tell you what DPI setting has just been selected by flashing the Human Ergonomics symbol a certain number of times. Overall, very easy to use this setting and cannot say that I have used any other mice - save a couple high-end gaming mice - that allow you to change DPI settings this easily on the fly.Overall, despite some small setbacks, I'm a huge fan and would recommend this mouse to anyone shopping in this price range. Please be sure to read other reviews - especially from users with different hand sizes - to make sure you get a good idea of what their experiences are with the product. As stated earlier in the review, my hands have an odd size and should not be used as a basis for how this mouse will fit in your hand.

I just purchased this a few days ago and so far I have been very happy with it. It took only a few minutes to become accustomed to using it and the usual aches and pains I experience using a regular mouse have been absent. The buttons are responsive, but not too responsive and the wheel is smooth to operate. It is overall comfortable, but some type of a wrist pad is required in order to keep the hand in a neutral position. I have used it on both a PC and Mac without any difficulties. Admittedly, I was a bit cautious at first, because when I went to their website to obtain more information, it was difficult to understand what was being stated or find all the information I was looking for as the translation is a bit rough. But so far it's worked well. If anything changes over the next few months, I will update this reviews.

I bought the mouse almost a half a year ago. It is more or less fine, quite a solid product.The only problem which is really big for me. I am a Unix software developer. In Unix we have to use a middle button a lot. It works as "paste selection", no copy and paste separately. Even more, Control/C in Unix mostly means "interrupt" not copy. In this mouse middle button is combined with the scroll wheel. At the very beginning I found that for the middle button the pressing effort is slightly higher than it was comfortable to me but later I adjusted to it, mostly. With time I began to hit a problem, duplicate paste. I press one, I hear a single distinct sound, but I got two copies of selection. It happens more and more often, up to 50% cases. It does not depend on the force and speed of pressing, and I found no way of making single paste whatever I do. Sometimes I see three insertions! I cannot bear it.I tried to contact support. The only way of contacting is to send e-mail to [email protected], somewhat weird. I got no response in six days. Registration on site is not smooth either. You cannot resend e-mail, it always fails, but in reality it might send, just went to junk. I got an activation mail in Chinese, just need to click on a big hyperlink in the middle without reading. The web page does not give anything new to solve my problem, no product registration, no in-site mail or other types of contact.Anyway, I am going to exchange my mouse with somebody who is not a Unix user before buying a mouse of other brand.

The Mouse is very comfortable and I can already feel the lack of tension on the muscles in my arm from having to turn my arm over flat for a traditional mouse. One minor problem is the wireless adapter is in the base of the mouse - the documentation nor the box directions mention this. The cable comes with it, so I thought I was shipped the wrong product, but when I went back to Amazon to get the correct product, I saw the picture in the ad showing the wireless adapter in the base. The installation of it was automatic and I was using it in wireless mode in about 5 seconds.

wow. Not cheaply fabricated at all. What might fool some less astute folks is the very lightweight, almost weightlessness of the product which is part of it's therapeutic value. It is aesthetically pleasing AND fast and accurate. The best thing about it is that I got it for my wife who has arthritis and it relieved the pressure in her wrist and fingers making her feel much better (and we all know about a happy wife/happy life). Have had this mouse for over a month and so far so good. Overall I highly recommend this mouse to EVERYONE and especially gamers and those who have hand/wrist issues!

I own a small business and my mouse and keyboard are my life. I just returned the new Logitech master mouse for this one and I have to say that I am pleased with this mouse. Very comfortable, good for my large hand size. This mouse seems well made. Maybe a little flashy with the light up feature which rotates a series of colored lights against the logo. I recommend this mouse, but might need to go back to the new Logitech master mouse as the scroll wheel on that mouse is like a Ferrari compared to this one and most others.
