oh my,, lenovo is a good brand and a bit expensive, too.. getting any Lenovo item for less than 50 PHP is crazy.. too good to be true.. I had a Lenovo mouse and keyboard set for 1200+ php,, and I got on sale.. and it's still working until now, it's been 4 years since I got it.. maybe you got a fake Lenovo item??..
but good thing you got another good quality mouse,, rapoo is my favorite electronic brand.. I have my new mouse and keyboard set from rapoo.. but I still have doubts, 143 PHP only?? that's cheap.. I really hope you got a genuine item this time..
good luck @wanderelle
