E-YOOSO Large Wireless Mouse >>>>>>>>>>>>>>>Update Sept 23, 2023, It is even worst if you can believe that. I put a brand new battery in the new mouse they sent me when I got it, that might have been a week after I wrote the first half of my review around July 24th. That battery died two days ago so I put another Duracell Optimum in the mouse. Both left and right mouse buttons now fail to work a good percentage of time. Left click on a enter button or continue button and nothing happens, I second guess that I didn't click hard enough but lets face it folks, when it happens more then it doesn't, I say the mouse button is failing. Right click for menu options and nothing happens, could it be I failed to click hard enough again? Ya okay sure! It's all too bad because after two months of trying to use it, I have grown to like it. It now feels good in the hand most the time, but not always. To adjust for the sticky part, I have slowed the movement down to the lowest setting and that stinks because I have four monitors and that is a lot of picking up the mouse to keep moving across all that screen real estate. The price was right if it worked, I'll keep a watch on this brand in case they come out with something new and better. Thanks for reading another review by the Abe..............>>>>>>Original post:Almost comfortable-ergonomic and value for money if it wasn't so uncomfortable and non-conforming to my hand. What I have such a hard time getting past is the left click button only working about 65-70% of the time. For the past unknown number of years I have used a MX Masters, MX S2, S600 "yada yada". So when the M720 started acting up I thought I would try this monster since it said it was LARGE. Yes it is and I like that, that is the end of the "Like" list. Nothing else about this mouse is nice. It almost fits if not for the weird shape. I can't tell if it is too short or too long but it is too something. The height is just right accept it is too far back, if only it was a smidgen further forward. The pinky finger drags along and kinda adds stability when the mouse jerks a little when you're trying to make those oh so little moves, it feels like the gliders are just a tiny bit tacky and when you try to move the curser just a small amount it grabs and releases and you over shoot your spot. I think I will put my old Logitech S720 back into service.Sometimes you don't even get what you pay for.

Worked flawlessly. Fits comfortable in hand

I really like the ergonomic design and the way it fits my hand. However, the movement is very herky jerky. Would not buy again.

I needed a mouse that better fit my hand. This mouse is it. It only took a few minutes to adjust to it but once I did, it was just what I was looking for. And the operation is great. Recommended

Good mouse

Waste of money

My last mouse came with my now five-year-old computer, and daily usage eventually caught up to the poor creature. I like the convenience of a wireless mouse (the last one I had attached to the computer’s USB port), so I ordered the E-Yooso wireless mouse. This new mouse was wonky at first and froze up a few times, but it’s proved quite convenient after a week or so.The E-Yooso mouse is larger than most I’ve used. The mouse is only available in black. It’s ergonomically designed for right-handed users. The mouse’s body is 2 ½ inches wide at its widest point (where the side buttons are) and about 5 ¼ inches long. At the bottom of the left side of the mouse is a 5/8 inch wide wing where right-handed users can rest their thumbs. The mouse has a smaller wing on the right side as well. I am five feet eight inches tall with average-sized hands. My first two fingers rest comfortably on the left and right mouse buttons, with my ring finger on the right wing.The E-Yooso mouse operates via a dongle that plugs into any USB port on the computer. It’s a simple plug-and-play operation. The mouse is powered by one AA battery (not provided) in a compartment on the mouse’s underside. Once the dongle and battery are in place, the mouse becomes operational automatically within a few seconds. According to the Amazon sales page, the battery should have an 18-month life (the mouse has a sleep mode). I haven’t had the mouse anywhere near that time, so I can’t say, but replacing AA batteries isn’t expensive. However, considering this mouse’s price point, I think the manufacturer should have supplied a starter battery.Besides the standard left and right buttons on top, the E-Yooso mouse has a wheel to scroll up and down and a button just below the wheel that changes the resolution. There are five resolutions available between 800 and 4800 dpi. Finally, on the left side of the mouse are buttons you operate with your thumb that cause the page on the screen to advance or go back. There is also another opening on the underside to store the dongle if needed.When I started using the E-Yooso mouse, it would malfunction occasionally. The pointer on the screen would freeze or move erratically or sometimes jump around the screen. This happened about five times in the first week I used the mouse. I learned I could solve the problem by using the tried-and-true remedy for fixing computer glitches. I removed the dongle from the USB port, waited a few seconds, then plugged it back in. The mouse responded normally after that. After about a week of use, the problem disappeared, and I have had no trouble with the mouse since then.I would give the E-Yooso mouse a five-star rating if not for the freeze-ups I experienced in the first week of using the device. It fits comfortably in my hand and has several valuable features other mouses I’ve used didn’t have. The back-screen button is beneficial. And set-up is pure plug-and-play in seconds. I don’t know why I had problems with the mouse, and I don’t understand why they went away after a few days. This isn’t a matter of a mechanical device settling down after some use. For all I know, the problems could come back, but there’s an easy solution. So, I’m giving the mouse a four-star rating based on my total experience so far.NOTE: I received this product as part of the Amazon Vine program.
