CENSI Newtral Ergonomic Mouse,Vertical Wireless Mouse - 2.4GHz Optical Vertical Mice : 3 Adjustable DPI 800/1200/1600 Levels

Amendment to the below: I was hoping this was going to be the one, but it is not. It is awkward, does not track smoothly, and going to sleep and having to CLICK to wake it up is maddening. Because wherever the position of the mouse was where you left it, it clicks on that object and will open or close, or select what the pointer is open. What is with this click to wake. Why not the normal shake to wake. Thus, this mouse is going back....I bought the left handed version because I like using my mouse left handed. I have not installed it yet, and I believe this angled hold to it might take a little getting use too after using a level mouse for the last 29 years. I've grown tired of the Logitech mice crapping out after a year. The single click takes on a double click nature due to a connection under the button going bad. I still have older Logitech corded mice that do not have that problem, but I want wireless. Cut the cord, you know. This mouse is nice and tall and a good fit for a large hand. When I do put it into service when my current one fails, which it is showing signs already of it coming, I will update this review.UPDATE, just days later after I had enough with the M510 mouse failing. This will take some getting use to with my hand at an angle and not level. Going into the mouse properties, I was able to switch the left and right buttons. I use it left handed, but I keep the normal left button configuration as the main button. Sometimes I grab it right handed, and when others switch to the right mouse pad, easier not to confuse them. I am not using the extra side piece which holds on magnetically. I prefer grabbing the more flat side with my little finger. Mouse does go to sleep fast when not used. Shaking it does not wake it, too bad. You have to click a button to wake it. That will take a lot of getting use to. After shaking a mouse for over 11 years, you would think the shake to wake thing would be standard on all mice. Had to look that up on-line since the mini-directions with the mouse did not mention it. I do wonder why the left handed mouse was $13 less than the right handed. That is odd too.

I just got into trying these vertical mouse. DELUX small is pretty light, slides well, quiet!! and pretty precise and smooth for my small hand. This NEWTRAL is is more flat but at maybe 30 some degrees vertical. It's slightly large but I am very comfortable with it. Love how thumb dips in deep but this is not the quietest but not so 'clicky' loud though. The other vertical ones either hurt my wrist or very awkward. This NEWTRAL mouse carries a good amount of weight and it's nice. I wear close to small-to-medium small fitted gloves if that comparison can give you some idea about how comfortable this mouse can be in your hand. I love resting my palm on this mouse maybe slightly too round curvy and the wrist is painless as I move the mouse but can feel heavy to some if you are used to a lighter mouse like SANWA's pictured here. These (see photos) are my five affordable mouse and I like how they move on the screen. I want to say that NEWTRAL moves with nice precision and maybe it's because of the extra weight. With DELUX, I have to move with intent to be precise with it to the smallest icon I want to click. Some other mice (not pictured here) I had to try it for a week or longer just to see how I like them. And usually the pretty ones are not the ones that I usually end up keeping. It's the unexpected ones that are slightly bulky but with good curvatures odd looks and how they are simply positioned for clicking and rolling. After using SANWA (20-degree tilt and 25-tilt).. Newtral feels a lot heavier. SANWA is initially another awkward one if you are not used a "vertical" or tilt mouse. Initially, SANWA 20-degree feels too flat I mean literally flat left and right clicks feel just so weird to touch and click but eventually feels very comfortable in your hand to my preference. Also, the unusual or unfamiliar large bottom is just a bit awkward with SANWAs. But once you get used to SANWA seen in photos here and sold on Amazon as well.. I think it's hard go back to this Newtral lol Also, SANWA's clickers are noticeably quieter almost zero clicky and much more precise to sliding because of the lesser weight than Newtral. These are just my observation and preference though and I am very picky. If you like using one of those Vicsing, Lodvy (seen in the center of the photos included here) or Technet nice little mouse ($7~9) if you know what I am talking about.. I think you will like some of these mice in the photo I included here. But Vicsing/Technet/Lodvie's clicker is very noisy when I use them in library or in a office setting which can potentially bother other people. The Newtral clickers take a bit of effort to make sure they click and do their job compare to the other ones and again a bit loud. Anyhow.. I like all of these mice in the photos but it really comes to your preference and comfort level eh. I might be actually returning this Newtral one (NVR mind I'm keeping) because it feels much heavier and cumbersome. One more thing.. that xtra side palm rest that came with. Some might appreciate it but it's not for me.

I like that this is a decent price for the advanced functionality & ergonomic design, when comparing to a couple larger brands. But, big mistake I made: the “large” size is WAY too big for someone with smaller hands! My hand can barely fit it, so the extension for the left side of my hand is obsolete.The attachment is very easy to use- magnetic & stays in place well enough. It just makes the large mouse even more too large for my hand. I would recommend a female opt for the regular, not large. This large model is more made for men with actual paws.It isn’t overly complicated like some bigger brands. The drivers don’t require a separate app install & are automatically registered upon connecting the USB port. After placing the AA batter (for the large size), it’s just a flip of the switch on the bottom & connected! And, the USB nib has a storage compartment on the underside of the mouse, so you don’t lose it if you disconnect it. The battery is not included.Functionality is exactly what was expected. The additional buttons can be programmed for certain maneuvering in specified applications. The design is comfortable. It glides smoothly with minimal effort. I am on my computer daily, with a variety of functions from AutoCAD drafting to graphic design & the basic administrative/data activity- this mouse is fancy enough to cover the advanced needs without forking out for an expensive gaming version.So far, I’m happy with it, minus the large size.
