I loved that they were great shape and size for my table pieces for a sweet 15 im doing but i was upset to know that not all ten lights came in blue i got a green one in a set. I ordered two more boxes so im hoping all 20 come blue. I have 30 vases to do and one without lights is poo .Very pleased with this product.I used these lights to put them in a clear plastic ornament. I then hung them in my windows for "Blue light" to honor heroes of 9/11. One order was 10 light strands. I ordered 2 sets. They arrived in good condition,wrapped separately. They all worked(every light lit). I was worried about how long the batteries would last. I needed them to work for 4 nights. I had them on all 4 nights a total of 25 hours and they all still worked. I was extremely happy with these lights.I'm using the lights for my center pieces and I love them.!I used this for centerpieces for my granddaughter's wedding. There was just enough for a 14" wreath centerpiece and added just the extra special touch to the centerpiece.Just like they were described. I bought a the blue color, they look awesome just what I needed for my baby shower centerpieces. Only downside is 1 pack didn’t work.Oh my God this led light, they look very good, i used then for a birthday decoration ,the guests love them, they are tinny light ,but they was exactly what i wanted.I bought these fair lights to put inside glass center pieces for a quince I put togetherVery Happy with results!! And they are easy to use and shape. I plan on buying more. They are a sapphire blue when they are light up and they are pretty bright!!I love it!!!! They are bright and small perfect for small and medium projects. Battery life is normal. The only thing I don’t like it the tiny screws to change the battery ….. but they provide you with the tiny screwdriver to open them.I didn’t realize they came in a 10 pack. Very surprising when I opened the box lol! These lights although they’re tiny, they’re BRIGHT! I bought them to use on my mini Christmas tree and it works great!Ich hab sie für einen kleinen Weihnachtsbaum benutzt, sah super ausBeautiful colour looks so cool on a small sky blue tree or lake blueI can't rate the battery life because I haven't used them yet. They are very bright blue lights. Very pretty
