Grabit screw extractor

Grabit screw extractor
Has anyone used the Grabit screw extractors or any other brand of them?
I've read the reviews at Lowes.com and there seems to be an equal mix of good and bad experiences with the tools.
I need to get a bolt out of the cranks on my mountain bike, but I don't want to waste money, or break the tool off in the bolt. Then I'll have to buy a set of cranks instead of just a new bolt.
I don't know the bolt size, I do know it's around a 1/4". I'm thinking the smaller the bolt, the smaller the extractor, more the chance it will break off, so I'm trying to find out the quality and durabilty of the extractor.

Don't know anything about them, but I looked it up, and it looks like it's only for biting into a stripped screw head. If that's not what you've got, it won't do any good.
Easy outs are the classic for something where the head has snapped off. People swear by them and at them. They CAN break off in the bolt.
Stuck fasteners are always a crap shoot. PB Blaster, heat, and believe it or not, wax can all work sometimes. The wax trick is really surprising. Just drip a candle onto the bolt -- apparently some of the wax works its way down and reduces friction. It worked the one time I tried it. Probably best AFTER you've used PB Blaster or something like it .
Good Luck,
