A thank you to Melvin Adams, Quality specialist at Battenfeld Technologies.
I bought one of their Wheeler Engineering Deluxe Gunsmithing Screwdriver kits and I stupidly managed to snap off a small hex-bit in a screw. I sent them a letter and returned the busted bit and they returned 3 replacement bits for free.
Mr Adams also included a personally signed letter letting me know if I ever have any problems to give them a call. I'll be doing more business with them and buying more stuff. All I need know is my "CRuffler"
