I got a £6 mouse to replace the single AA battery ebay buy from 3 years ago. That was a £13 proper laser ( the invisiable bit that comes out the bottom). Battery lasted for ever and with a quick wiggle it woke back up. they don't seem to be on ebay anywhere, not even the make is there in search options.
Best current thing for a ok price from here ( old one was china so takes 3 weeks to arrive but normally cheaper, no disrespect to any uk seller reading this!).
other cheaper options, but might get caught out as I did with the cheap £6 replacement last month of it being a blue LED shining out the bottom, eats batteries. at least £1 shop rechargable AAA of low quality.
Laser mouse , I got a good 6 months use and did not turn off at the switch under it.
These may be optial, I now have and got so good on batteries or tracking on all surfaces but goes on the leather sofa arm!. My one not sure about these, just examples of optial I guess as no mention of it being laser, more dear ones are I now learn't the hard way when getting new one weeks ago.
This says laser so could argue if not.
To be fair as just looked at what I bought was optical, was after laser. Better tracking and run for longer. My old one 6 months on 1 AA alkaline, and can get packs in the local 99p store. Batteries are not a problem if bought from the right place!.
Nice to have no wires.
I have this, does the job but gone through 2 sets in 4 weeks. If rechagable then not to bad, laser mouse for normal or expensive to run optical mice.
I got rechargable.
Some come with them and charge by plugging into usb hole. or no batteries but supply your own.
I had these arrive 3 days ago for this ok mouse but not real laser like my old not existent one on ebay anymore.
What I think on the subject anyway.
