lychee Pocket Pen Mouse Rechargeable, Left/Right-Handed Optical Ergonomic Mouse with Bluetooth and Stylus Function (Grey)......

Short of the now impossible to get Logitech standup track ball, this is my favorite style mouse input device. I have a lot of hand and wrist issues especially during heavy input weeks. Due to such, I have learned to mouse left and right handed. Which is where this device proves to be very versatile for me. It is light so one isn't straining due to weight. This model has a usb that it connects with and it is tiny. I superglued a lanyard to it because if you loose that tiny thing you are SOL. I'm that kind of person that if I find something I like, I'll buy a backup. In this case I upgraded and went with the newer model that has bluetooth.

I enjoyed having the ability to move around my classroom and write on the board at the same time. My students also enjoyed the challenge of writing on the board *neatly* with it. It does take some time to learn to use it and my writing definitely wasn't the neatest but it was still handy. That is until the dongle fell apart the week after my return window closed. Sadly, it just sat in a drawer for the rest of the year.

These are basically extremely cheap mice in an interesting form factor. This particular one, if they haven't done any product swapping lately, is one of the better options on ZeeBooth - it has a mouse wheel which is capable of middle click, and it can connect over Bluetooth without needing the dongle plugged in. There are a lot of alternatives that look the same with different brand names, and don't have all of those features. I bought 3 of these at once after I saw what the first one was like, and 2 of them worked out of the box, the 3rd one I had to return in exchange for a working one because it could not scroll. One of the 3 is already wearing out after less than a month, it has started doing "double click" or "zero click" instead of a single click each time I press the mouse button. The batteries in these are atrociously bad, unlike a standard wireless mouse that might last 6 months on a single charge sometimes, these will not last from one day to the next without charging. I'm sure that means all 3 of them are going to wear out to the point of not holding a charge by the end of the year. But, I find them remarkably comfortable to hold; in particular because you don't have to have ONE position that you always hold your hand in to use your mouse. Vertical mice temporarily eased some of my RSI pain, but pretty soon started causing pain in different spots, because you still have to hold it exactly the same way all the time. With these guys, you can change your grip, hold it between different fingers, turn your hand upside down, and you still can have a usable 3 button mouse. It's just too bad that these are the only ones that anyone seems to make, since they are made of such junky parts. The wheel is terrible (too stiff, inconsistently functional,) even when it works, and I can tell they're all going to wear out. I have the one with the left click starting to crap out on me already, and the connectivity and battery life are essentially garbage. A Logitech in this form factor, with quality hardware that lasts longer than a single season, would be AMAZING! But unfortunately that doesn't exist.. so a bird in the hand is worth 2 in the bush, despite the unfortunately wasteful practice of buying junk electronics.

Only crappy part is you can't charge it with a fast charging cord. Has to be an older version. Which took me forever to figure out and I thought it had broken in the first three days I even had it. Wrong. Works like a beauty

Absolute crap. Difficult to pair, and no instructions on how to pair. Once I figured out how to pair, it worked for a couple days then stopped working. Attempted to charge, without success. I just wished I kept the packaging to be able to send back for refund. ZERO stars, as it is not a star product. However, a star had to be selected in order for this review to be submitted. ZeeBooth, you need to work on accepting ZERO stars with comment review.
