Agree. I had an issue with mine (unremovable mark on lens), contacted Alvin and he sent me a replacement laser mechanism. Took 15 minutes to swap one frame for another and it now works perfectly without sensitivity to bass from my speaker, 16" away from the player. Alvin replied to my e-mails within hours and when that did not work a new mechanism was forwarded. If I can replace the mechanism, anyone can. Sounds brilliant.
