Just to note on the jebao wp25. I bought one from C328 too. Less than an hour after using, I got the "3 lights blinking problem". If anyone of you happens to encounter this, the problem is with the adapter plug and not the controller.
I had to go down to C328 twice, once to change the controller(still same problem) and then to change the adapter. Have to say the auntie was very accommodating.
After changing the adapter, the problem is gone, HTH.
