stopped working today, 3 m old, nothing seems to fix it. new battery but my pc cant detect it anymore

Have had this combo for at least 18 months now and has served me well during this time however mouse stopped working today (yes batteries replaced) and only other issue is some of the letters on keyboard have worn off. Apart from that when you consider the low cost it is definitely value for money as I use this every day!

Works well until it doesn’t.
Worked fine for a few months, then stopped connecting with keyboard and mouse. Tried lots of solutions. Now it’s just another piece of e-waste. :(

The dongle for Keyboard and mouse is broken in the very first day I use it.

Keyboard is nice to use as is the mouse and it is good value for money. The only down side is that the mouse is a bit vicious on the batteries if you forget to turn it off when not in use. I'm replacing the batteries at least once a week if not more frequent. All in all good value for $'s.

so far so good - soft touch keys and sensitive mouse, for a budget price - you can't go wrong! could be a good option for a smart TV but I haven't done that yet, note: keys are closer together than my previous keyboard so I'm just getting used to that (extra letters in sentences etc)
