The Ergonomical Mouse - Wireless Optical Rechargable Battery Vertical Mouse - 2.4 Ghz, 6 Buttons - Adjustable DPI

The person that this was purchased for had a shoulder injury. The regular style Mouse was causing a lot of pain . Just one month later this person has no pain at all due to using "ERGY" . Thank you.

The good - Wrist pain is just gone!The scroll wheel is a little too far away and I wear size large gloves. I've learned how to hold it differently than what was natural. Forward and back buttons are awkward. Press the front one and hold the mouse from moving and you generally press a right click or left click.Wish it had a little weight to it. Feels really cheap. Well, it was.Really easy to tip over. End up knocking it on it's side at least once a day.About 40% of the time, when it falls asleep, it's done. Fully charged. Cycle the power switch, nothing. Click buttons to wake it and still nothing. Have to move the dongle to another USB port to get it to respond. I keep a wired mouse attached so I can work around this when I have to. So not ideal.Update - My review knocking a star off wasn't published. Oh Well. Device was failing - had to unplug the dongle every time the computer went to sleep because the mouse was non-responsive.Now, Finally died. One Star! Logitech has a mouse that will work.

It didn't work for me but my husband will be able to use it.

super comfy to use. It was weird at first but I love it now!

After using this mouse for 20 minutes i gave it to my room mate. Not any more comfortable than my Logitech MX mouse. The DPI switch does nothing. Thought some special app would come with it but nothing else was included. My thumb could not reach the 2 browser buttons without removing my hands and repositioning my hands on top. I have an average size hand so those buttons are inconvenient to use.

The scrolling wheel broke after a week of use. Very disappointed in the durability of this item.

I love it.

This would be a pretty good mouse i think, but the forward and back browser buttons are opposite of every other mouse in the world (they are switched) Makes them useless for navigating files, internet, etc because it is polar opposite of what everyone is used to. WHY?Edit.....minus five stars. The mouse wheel fell out of position in the mouse. cannot be fixed. tiny shitty plastic shaft extends into cheap rotary analog encoder 1/16", it wears, falls out of encoder and that is it. Its fubar. There is no way this product was ever tested in any way. failure in 2 weeks of use.

The first order was horrible. It came in a very loose and open pack and with missing pieces: no usb connector nor charging cable - which made it impossible to use. After asking for a refund or return, I received the correct piece. Very good and sturdy pack and all pieces inside. I wonder why I wasn't sent a decent pack in the first place! Anyway, after receiving a proper piece, I am satisfied with it. It takes a little while to get used to it, but once you get your fingers to be in the correct position it is very comfortable. I was already using this type of vertical mouse before and now I can't go back to the traditional ones. It makes a huge difference. This one has a red light when charging and it becomes green when the charge is complete, which is also helpful. I've been using for more than 2 weeks now with a single charge. It also goes into sleep mode when not used for a while - which is good for saving charge - and it comes back quickly but just clicking any of the buttons. The side buttons are useless tough, I think they are there only for decoration! But overall it is a very good piece, it seems sturdy, the charge last very long and it makes a huge difference for the comfort/pain in the wrist.

The product still works well but the battery doesn't charge. So it has become a wired mouse.

Good mouse for this price. Quality of the product is not up to the mark. But wrist pain has reduced compared to using the normal one.

Wrist pain, arm pain was the reason i looked up for a vertical mouse.Ergy was fitting my budget, and went in.Been one month using it and it feels awesome.Getting used to the new mouse takes around 3 days. (6 hours use per day).The buttons near to the thumb is unusable, because if you try to click it, the index finger clicks the left-clik-button on the other side.Its not bothering me because, i am okay not using that feature.The charging port is another big bonus.The charging light turns green to indicate full charge attainment.The paint job on the mouse is a bit low end, cause I can see the paint wearing off from the mouse button in the shape of my index finger. But the feel of the paint is matte, and hence comfortable.The mouse has autoshut off ! - in two ways!Leave it not moving,for 5 seonds, the laser turn off.Leave it not moving for extended period, the mouse completely shuts off. Clicking on any mouse button bring it back to life.Overall happy with the price and the product.Will revert after 6 months of use.

A few things to know before you buy this -Pros:1. Has sufficiently good scan speed (DPI) for regular work2. It is a vertical mice, meaning your hand would be twisted on the right. Should not be a problem if you don't keep your elbow on the chair armrest. if you normally keep your elbow on the armrest, this would be uncomfortable to operate for long.3. The vertical mice should only be used if you have carpal tunnel syndrome or tendronitis. Else, this is not as comfortable as your regular mice.4. Most of the Vertical mouse have terrible precision barring a few very expensive models. This one does the job fine and you'd not notice any lack of precision until you try to play a FPS game or use AutoCAD for vector drawing. I do both, so it doesn't suit me.5. Overall quality of the product is nice barring the sharp corner at the top. The charging cable is of sufficiently good quality.6. You can use the product when charging also.7. Goes into sleep after a while of inactivity, just click a switch to reactivate. Sleep mode is well implemented and works well.Cons:1. Inter-mice message time is around 8ms in my model, which is achieved by every cheap chinese mouse (Comparison: my Logitech M330 has around 2ms, costs around 20% more than this). Should not be a problem if you do not game on it.2. It has terrible balance. Try to move fast and it has the tendency to topple on the left side.3. It's very large in size compared to normal desktop mice. Certainly not for people who have small hands.4. The handgrip is very slippery and is a challenge to hold on to, especially if you have small hand.5. if you have larger palm and smaller fingers like me, operating the keys prove to be a challenge.6. The back and reverse buttons on the side are not programmable and their function is very limited.7. The overall outside finish is very slippery.8. The on-off button protrude above the foot dimples and makes the mice wobble around that point. Due to the same reason, it can't be used on any good fabric-based mats/pads. It's good for hard surfaces only.
