Title: Dreaded noOp Sign but hammering works
Review: UNlike several other reviewers I have had this product for about 4+ years & had been working fine until today. I got the dreaded "noOp" sign. I tried replacing the battery & resetting a few times & nothing worked. I was about to order a new one when I read the bad reviews. Then based on other reviewers comments tried tapping hard with a tool on all sides & sure enough it started working fine. Dont know how long it will work but this is a good enough temporary fix before you can find a replacement.This product does seem to have a poor reliability but you may have temporary fix before you find replacement.
Is the review positive or negative?
