Question: What is the length of the wire strand?
Document: One worked great. One was defective and on/off switch did not work. Will need to return.Would have been better if manufacturer specified the length of the string.
Nice bright red lights, but really uses up battery life quickly. The wire pretty much disappears, so that's a good feature.
Bought (5) of these in different colors, only the blue set seems to be having a problem, first noticed a short if the wire was straightened out and then the battery pack started to smoke.
Great little LED lights! They are very bright and have plenty of length.Off/Flashing/On switch is great and was very pleased with the quality.The actual LED itself is a weird miniature cylinder shape not like the typical rounded tip of many other LEDs.
they are very pretty but very delicate. I was unraveling them and one strand snapped into so I had a short strand. But again the light they give off is so pretty.
I bought three sets of these LEDs as part of my Halloween costume. These worked very well with the exception of a single unlit light on one strand (otherwise I would have given them 5 stars).
My husband got these lights to highlight a display box. They are just what he wanted. The wire is unobtrusive and the lights are nice and bright. The only disappointment is the blinking feature. When set to blink, it's more like a 70's disco! None the less, we do like the lights and will use it set to solid on.
I bought this to go around the umbrella on my patio. I didn't realize just how short 11ft is, as it would not even go around the umbrella once. The light it let off was not bright at all, and the battery casing is way too big and heavy for such a small strand of lights. Thumbs down on this product.
This product clearly stated that these lights had a &#34;twinkling&#34; setting, I found out that this was not true. Instead of a twinkle it was more like a strobe light. Also most of the tiny strand didn't even work, and the more they were handled the more lights went out. I hate that I wasted my money on such a crappy item. Just don't buy them. Complete waste of money.
I ordered two strands. The battery cases were much larger than expected. When I inserted the batteries, the electrodes did not come in contact with the metal conductors because they were obstructed by the plastic case. One strand works fine, the other broke after one day- lights became so dim they were barely noticeable even with a battery change.
Answer: yes
