Title: Returned numerous times - on every one, the display shorts out.
Review: This product does not work. We returned it numerous times and every one had the same problem. We would plug it in and turn it on. After a short time (5 seconds to 1 minute), the display would blank out and not come back on. None of the buttons would respond either.The problem would only happen with the plug. When I removed the plug and used batteries, it would work without problem. But, even if I left the batteries in, it would die shortly after plugging it in. This wasn't an acceptable solution because I wasn't going to run through batteries all the time.We tried the DD50 and the LDD50 - both had the same problem.
