Shenzhen Aidisen OptoElectronic - Have you had failures?

[dmoore]

Last year I order items through Ray that came from Aidisen (http://www.aidisenleds.com) that had very high failure rates for me. On the basic RGB 5050 modules, I was getting a 10% DOA failure rate and on the 6803 pixel modules I had two failures out of about 100. I'm wondering if anyone else also experienced any problems with the same types of items or was it just items I ordered?

* 6803 Pixel Modules:

Some of the stuff i got last year was from Aidisen. I must say though that i didn't have any more than expected failures, in fact everything worked straight up, just had a couple of failures during the season but nothing out of the ordinary (2 modules out of 600 failed)
I plan on having some quality issues as these are products coming from China that have had little if no quality checks, but then the price is a lot better than if i bought from a local distributor that would have these quality checks. So i always factor is approx 10% failures.

In the end you pay for what you get, i believe it may be a bit of a lucky dip sometimes but if you pay through Escrow and give yourself some protection and then ensure you test all your goods immediately upon arrival and give them a small period of burn in testing before signing off on the Escrow payment. That way the transaction is still within your control to negotiate any differences or price adjustments for any failed units before signing off the transaction.
