If you are using an HID, require precision, efficiency, or being able to use all the outlets on your power strip cleanly without a squid or foul looks from inspectors, then you need to lose the intermatic junk and get with the Stanley 38425 TimerMax Digislim Daily Digital Indoor Lamp Timer, White, 2-Pack for 5 bucks more and thank yourself for not being retarded.The real question is not should you buy this POS analog timer, it's why did it take the industry 20 years to make it obsolete with the Stanley?Now when I'm home alone and set up timed events to scare off the crackheads I know it works every time!
