lychee Optical Pen Mouse Wireless for Laptop,Ergonomic Pocket Mouse Pen&Adjustable 800/1000/1200/1600 DPI,2.4GHZ USB&Bluetooth Mouse for PC(Grey)...

Unit failed to stay paired and now fails to pair. It worked for a day. I was holding down left click while painting in a drawing app (for more than 20 seconds) and pen launches the ai office url and mouse stopped working. Installing the app never finds the mouse and does not find the included BT dongle. Fails to pair on my win 10 machine and is never "seen" while trying to pair to my android phone.

It has both voice and mouse options but the product is cheap plastic and not made for long term use

I was initially a little dubious about using a pen-like device as a mouse replacement, but overall I have been pretty impressed with this little gadget. It's very lightweight, almost to the point of making it feel cheap. Basically, you hold it like a pen, and the button which emulates the left mouse button on a conventional mouse sits under your index finger, while the scroll wheel is slightly behind it. The right mouse button equivalent sits under your thumb, and you simply move the pen around to move your mouse pointer as if you are writing. The version I received is only suitable for right-handers, so southpaws are out of luck unless there's a dedicated left-hand version available. The back of the device has a small capacitance nub on it so it can be used for touchscreens on your laptop or phone - pretty handy. To use the device, you must insert a AAA battery (not included) by removing the back part of the device revealing a small battery bay. There are no markings at all on the device indicating the required orientation of the battery, nor is this indicated in the included instruction booklet. Trial and error revealed that the negative end is inserted first, and the device powered up once this was done. Installation is easy - it comes with a small yellow dongle which is inserted into a standard USB port on your PC, and assuming the pen-mouse is powered on, it immediately pairs with the dongle and can be used immediately. There are also adapters included with the package to adapt the dongle to USB-C and micro-USB ports if needed. An app must be downloaded to realize the full abilities of the device, which supposedly includes the ability to use it as a voice dictation implement. I say "supposedly" because after two attempts to install the software, I could not get it to run or function in any way on my Windows 11 laptop. Not sure what the problem is, but I have to take off points because of this. Perhaps I'll be able to get it installed and working at some later date. The pen-mouse comes with a small desktop holder which is a little tippy when the battery is installed but keeps it handy and out of the way when not in use. Using the device takes getting used to, but the angle that you hold it is natural and comfortable and requires no real adjustment. It seems responsive enough for normal mousing but doesn't seem suitable for gaming. The main use of this device would be for everyday office computer use in which case it uses less real estate than a conventional mouse and is probably less likely to cause long-term problems. Recommended.
