i currently have the jw speaker 8700 evolution j and have been great until a month ago. they lasted right at 10 months and 1 started to have issues shutting off and on, sometimes it would would delay 10 to 20 sec before it turned on. i swapped lights l to r and followed light. installed factory lights and had no issues. contacted jw speaker and got no response at all by email or phone. i contacted who i purchased them from and they worked hard to get them warrantied but they also said they were having communication issues with jw speaker. over a month later i finally got a replacement light. i love their lights and i know there will always be glitches with products especially since it was a new product but their customer support is non existent for the price you pay.
