A few months ago, I bought a voltmeter and electrical tool set at one of those traveling tool shows that was in town. Later on I determined that it did not work. Iwas just going to toss it but then I sent them an email and miracle of miracles today I received a refund check. No requirement that I send them the non-functioning meter back. It did take them awhile (the lady I emailed with said they were undergoing a computer changeover and warned me it would take a while to get done) but its hard to quibble too much.
Incidentally, it appeared to me the meter they sold me is a near duplicate of the cheapo meter HF sells with a different brand name on it and a different color plastic. I bought one at HF several years ago for $5 or so on sale, and it works OK. Seems to read high on 480V but otherwise seems close. I bought it for taking with me so if I leave it somewher I won't be all that steamed up about it.
