Recently had a dealing with Adam for an older Busnell Holosight. Can't say I'd give him a perfect +1 though. He listed a used Bushnell Holosight with manual and I made the purchase and the sight was shipped on June 9, 2004. I received the sight but it came without manual. Sent Adam an e-mail about the missing manual and got a reply on June 15th that he thought he had put the manual in the box but would check on it for me. Waited about a week and sent him another e-mail on the 23rd and still haven't received a reply to either e-mails. I'm not so much upset about the manual, as it is pretty trivial, but I am disappointed with the lack of follow through with this issue.
*** UPDATE ***
After some more conversation, manual was received on July 2nd.
