Rating : - Short life, good features
I used the DT17C for about 45 days before it went dead. The feature set is great, especially the ability to make separate weekday/weekend schedules. Unfortunately the quality of the electronic components is pathetic. The relay inside mine failed, causing the timer to not switch power to the outlet either in programmed or manual mode. A quick attempt at disassembly found that the darn thing can't be taken apart: there are glue points or permanent snaps that prevent easy replacement of the relay. I sent it back for a refund instead of risking destroying the timer. What a disappointment!
