I've had no problems with the kit. I bought this to fix an old drawer handle that couldn't be replaced. I clamped the drawer member in a vise and used a drill press to drill a hole of the required new diameter for a larger faucet. The insert entered the new threaded hole smoothly. The whole job took no more than 10 minutes. As mentioned, this kit does not include the required 11/64 drill bit, but I already had it. This kit also doesn't include the blue pre-needle threader, but I didn't need it. The kit did what I needed for less cost than the heli coil kit.
