This is a good rechargeable Bluetooth mouse and seems to do well as a mouse. I didn't test the USB receiver connection. It is fairly lightweight, but is what I'd call a full-size mouse, fitting nicely in my hand. The clear plastic cover is a bit slick, but easy to hold, and the buttons react as would be expected. The RGB lights are a neat addition. The included USB Receiver is securely attached to the bottom of the mouse. It doesn't interfere with using the mouse when left attached under Bluetooth use. The mouse may also be charged while in use, unlike the Apple Mouse which has its charging port on the bottom. You'll want to have a long and soft cable so it works like a wired mouse while charging, but that port is in the perfect location to allow this.Though the included instructions and the instructions on the product page should easily help anyone get the mouse connected, they don't provide a method to contact support, though they say to contact them with questions...which I have. The first of which is: should I remove the paper on the bottom over the 'slick' areas which upon inspection says ''remove', but they do not seem to harm anything when left on.Contrary to the instructions, the readout lights for DPI changes and Bluetooth/USB connections are on the bottom of the mouse, on the actual circuit board, and cannot be seen on top. On my device I was never able to get the 'battery level LCD display' to light up or display...and I tried countless methods during or after charging, in one of the 3 power modes: off, 2.4, and Bluetooth. I'm assuming the LCD readout is broken on my mouse, or my mouse is a lesser version and a light will illumine on the bottom when the battery gets low. There is also a reference to controlling the RGB lighting, which I'd like to turn off (both a distraction and uses the battery?). However, there are nor instructions on controlling the RGB lights.Again, this is a good Bluetooth mouse, but the lacking instruction areas, and the unusable LCD battery level have not impressed me.
