Question: I ordered these and the first half come on the other half is dead. Any suggestions as to how to fix this?
Document: I received the lights in the mail three days ago.When i first got them, IT WAS A PAIN having to uncoil them. As for many string lights, the cord bunched up when unravelling them. I blame the way they were packaged, however with time you will be able to fix that.The lights themselves were pretty amazing. The shimmering effect was really serene and calming.
Only half the string twinkled and very hot bulbs. I returned them which was very easy. That made me happy.
These lights were defective out of the box. Only half the lights worked. Quality and workmanship is extremely poor. I read the many bad reviews and should have headed the warnings..
This is my second order of these lights, and like the first order,Everything went smooth, with fast delivery and every set  twinkling.I would recommend these lights to anyone. VERY GOOD SERVICE!! !
I ordered 6 boxes of these lights as of this date 3 boxes are not working, that is less than 1 month very expensive to be so unreliable, will NOT order them or anything from the company again
I ordered these lights because I was looking for tree lights that twinkle. These do not twinkle. They are just clear lights that stay on. If you are looking for lights that twinkle, don't buy these. If you want lights that just stay on, these are fine.
I love how they just don't blink on and off, I wanted only ramdom affect not a harsh all of them going on and off at the same time.UPDATE JAN 12 2013When I took off these lights at the end of the holiday, half of them where burnt out, bulbs where black. To many on the strand to replace so I just threw them out.Not impressed.
Only half worked. My guess is that I received a return from one of the other reviewer that had the same issue. For the half that works, I just don't see anything special about these twinklers. Save you money. There is nothing unique about the lights.If these were tested prior to being shipped they would have easily seen that they were defective. They are going back. I hope the company doesn't repackage them (again.)
First of all I didn't like the fact that the lights arrived in a totally different package than what is shown. The lights were tightly scrunched together with an elastic wrapped around two bundles of 50 lights each. Much cheaper packaging for the same price! Time will tell whether they will work after the first year although I only used one set and will save the others for my main tree next year.
First of all, This seller sent my package out without my complete address on the package. There was no excuse for that.Next, I had to contend with UPS to correct the problem which delayed my package delivery for 2 days.Then, when I opened my package I realized these lights string length is not 33' long (An answer to a question I sent to this seller) but 22' long... AND the cable is NOT white which the description says, but green.
Answer: Try replacing just the first light bulb that's out at the point at which the rest of the string doesn't work. It might be blown and not able let the current flow to the rest of the bulbs.
