Much of their hardware is decent.
Had to send back their $35 cordless drill. Came with two bat packs and charger. Torque was severely lacking. Not an all-around drill. However, was useful for the every day picture hanger and loose screw dabber and light-weight home projects.
Before you buy any electronics be sure to check out all customer reviews. It appears that they have issues with quite a few electric items of which they don't fully, or at all, disclose shortcomings.
Again, everything from gloves, to sandpaper, to wrenches, to sockets were good in my experience.
Watch their mailers and emails for great sales. Price swings can be wide and like other posters said, be careful buying more expensive items - known ALL return policies so as not to be surprised.
