i recently bought from andy and also on aliexpress from dragoneye security (mentioned many pages earlier from a buyer in australia). the dahua starlite turret from dragoneye (ali express) went kaput after 35 days. the contact at dragoneye (susan su) had always been a bit slow to reply about shipping, etc, but this time they really disappeared when i asked about help / warranty service. so while sales of these "international version" cameras are akin to rolling the dice, i really do NOT recommend dragoneye. my experience with andy has been much better.
as a quick note on getting whole with the camera that broke, i did buy the camera with my amex--and, after a lot of legwork, it was covered under accidental damage. if you have a fancier card (like a platinum) they even have return protection. but in the search to get a legitimate repair estimate as part of my amex assurance submission, one of the places i talked with was dahua N. America and dahua asia. and when they ran the serial numbers for my various cameras, they told me these were not in their database and not able to be serviced by them (as was probably mentioned in the prior 194 pages of this thread). if it had been sold by an authorized dahua dealer, it would have been covered by a 3 year warranty (and probably cost twice as much).
the camera i got from andy did seem to take longer to get dropped off to send--but the two i got from him still both work, and he continues to reply to my questions via email. sometimes i do ask some politely annoying questions about return policy, warranty, etc--but he does reply usually with a day or two. and he assured me if i had any problems to just deal directly with him for up to two years. his reputation on ipcamtalk is something he protects--so that has been comforting. if you have to roll the dice, the odds are way better with andy for sure.
i'm sure much of this is covered in this thread as well as in others, but just wanted to share my experience and thank the many generous and truly people who share their ipcam knowledge with we newbies.
