The nasty cheap supplied wrenches are usually to blame.

Anyone that uses the cheap hex wrenches to put in a new hex screw set....................................... well, should know better. If you are stripping numerous stainless screws you are either installing them crooked or doing something else wrong. Stainless hex heads are VERY hard to ruin.

Most experienced R/Cers have a good hex wrench set to use. Like a Hudy, or Trinity, or WEHA set.

Sorry to say butit's more often the user than the product. No sense in trashing the product line.
