I'm looking for feed back on the cheap hr meters some of you have bought from ebay. I have two and nether of them works. It takes 15 min. or more for the meter to move 1/10th. of an hr. and the blinking icon blinks erratically. The ebay seller is trying to tell me that I have a bad connection. I hooked a sendec meter to the same wire connection and it works. Is any one having any luck with these?
