I only had a disappointment when I ordered a driver from them, it never made it to me and he didn't have tracking to show what happened to it, no offer to make a reduced price for a replacement either
It wasn't a cheap driver, I think I was out close to 40 or more dollars, won't reorder. I'm more disappointed in the lack of their trying to make the issue right, but on the other side of that coin, I didn't press him to do so either. By now, this is probably long forgotten, it's been several months now.
All orders should go out with tracking so we can see if they shipped! I also have no reason to think he didn't ship it, but without that tracking I'm left with nothing but a hole in my wallet. If it had been shipped priority mail there would have been $50 insurance which is automatic for that class of mail, but he didn't do that either. I used to have a link to his web site in my signature for a year in the past too, because I liked his offerings, only left with disappointment now.
More his loss than mine, in reality, I have ordered thousands of dollars of laser parts from DTR, and once I am happy with a laser parts vendor, I keep ordering from them, a pity this didn't work out and I won't reorder and ask to make this good now, too late due to the lack of support on the problem or trying to work it out, no suggestions from them to do so, so I walked.
