I say 'budget' as it's just under £20 and that's really cheap for camera kit.
Good points, the wire is really long which is handy, the simplicity of it is great and I had it going for 48 hours whilst on a time lapse.
Bad points is that because it's just about £20, without a good wire, the camera did bleep at me a fair few times to say it was getting hot. (Barely warm to the touch).
Overall, this is fantastic, first time I used it though I didn't notice there was a little rubber flap on my 550D that you could squeeze when the battery flap was closed. But when it's plugged in and the flap closed, it's a constant power. The battery will say '100%'. Perfect for what you need. But I would recomend if you're serious about constant power, maybe a little more expensive one with a better resister might keep the camera cooler for longer. You don't want your 550D, 5D or 7D going off as it's too hot on a shoot.
