I ordered some kits from Laserlinez a while back and finally got around to starting some pens with them, prepared blanks and glued in the tubes. I put one on the lathe to start rough turning and the bushings didn't fit the tubes. After some screwing around and measuring things, it was clear that the tubes included in the kits were sized incorrectly. I contacted Laserlinez through their website contact form, and after a few days got an email back that replacement tubes would be sent out the next day. After a week went by with no tubes in the mail, I sent another email to inquire about the replacement tubes. No response to that email, so I sent another after 3 days. This time I got a response promising to send the tubes out 'tomorrow'. So two emails promising to send replacements 'tomorrow'. Maybe I'll get some tubes, maybe not, who knows? Poor customer service on multiple fronts doesn't earn repeat business from me, so the search for quality components continues.
