I recently purchased a Vz. 58 rifle. These are made by D-Technic in Czechoslovakia and imported by CZ and CzechPoint. Mine is a CZ, but the warranty work is all handled through CzechPoint, as they are D-Technic's designated representative here. The first time I fired it, it stove-piped perhaps every three or four rounds, so I contacted CzechPoint and explained the problem. I received an e-mail immediately from Dan Brown, their customer service guy, who said to send it back and let him know what the shipping fees were. He also offered some advice on the best way to send it back. I had a couple of questions for him, so I sent him another e-mail, to which he also responded immediately.
They fixed the rifle very quickly, and no more than a week later I got an e-mail and a phone call (because I didn't respond to the e-mail right away) from Dan, who explained exactly what they did to the rifle and that they were sending it back that day. He also again asked me for the amount I spent on shipping, so that he could enclose a check with the rifle.
I got the rifle back a few days later, and fired it yesterday. It functioned flawlessly, and there is no evidence of the repair (any unsightly machining or anything like that). The check was included in the box as well, and the amount was rounded-up by a dollar or so (woo!). Dan enclosed a note and an extra magazine, saying it was for the inconvenience.
I don't think I've ever gotten this level of customer service from a firearms company before. Their website discusses customer service and their philosophy quite a bit, and it looks like for once it's not just rhetoric.
Well-done, CzechPoint, and a big thank you to Dan Brown in particular!
