Nice effect, defective product The color changing effect looks nice. Each bulb fades through red, blue, and green several times, fades through pink, and yellow several times, and then repeats the pattern blinking. The bulbs are not synchronized, so after the strand is on for a few minutes, this creates a nice twinkling effect.The strand I received was defective. One section of lights would flicker a few times when plugged in and then go out. I am returning the strand for a refund, since it was shipped from Amazon, but I was unable to get a replacement since this product is no longer available shipped from Amazon.Update:A year later, these are still the nicest lights I could find on Amazon (aside from the really expensive GE Color Effects lights), so I decided to try again. I ordered two sets from different sellers (both fulfilled by Amazon), and they do actually work this time. However, though the two sets have the same name, they came in different boxes, look somewhat different, and have completely different model numbers… which I find a little odd. One is very bright and produces an almost white color over all. The second is a little dimmer, especially the green, so it looks more purple overall. I wouldn’t say it’s worse, just different.Since the different colors are controlled by each individual light, the dim green means the actual bulbs must have been manufactured differently between the two sets. Most likely one is from last year and the second is from a more recent production run. (If I remember correctly, the portion of my first set that actually worked looked identical to the dimmer set, and it came in a similar box.) Just be aware if you’re ordering multiple sets that they may be slightly different. I’ll leave the star rating as it is, since the mismatched sets do limit the placement possibilities of the lights.Aside from that, I think the blinking / fading effect is quite nice.
