Crap power supply
Crap power supply! Works great, when it works... but I tried it with 3 different brand batteries in it (NEW!) and it didn't work with them. Then I bought some cheap batteries at Fry's (T-Energy.. I think it was called), and it works with that. Then I tried swapping out ONE battery for another brand, it still worked (just barely), as long as one of the TEnergy bats was still in it. (This thing doesn't like: Duracell, Everlast, or Energizer brands, I guess)<br /><br />Instead of using AA alkaline batteries, it should have had a Lithium-Ion battery pack, with AC  adapter plug in charger, giving you the option either let it charge up fully and then use it, or use it on AC power, while plugged in.<br /><br />The AA batteries are just way too underpowered to run this thing for long. I got one or two uses out of it, before my T-Energy batteries couldn't handle it anymore.<br /><br />Other than power source, it works pretty good.  Does it's job, there is sufficient torque, and it is durable.... but again (and I can't stress this enough), WAY UNDER POWERED.
