Incredibly bright and pretty- the purple was really vivid.However, they did begin to break when exposed to the dust at Burning Man. So.. if you're decorating anything for severe environments I would suggest sealing the battery compartment.I bought two strings of green lights for a live two foot tree (narrow). Ran the lights for approximately six hours a day and replaced the batteries after ten days. The lights are brighter than I expected which was a plus. After two weeks of use, one of the on/off switches broke off.Overall I was pleased with the affect.These are gorgeous and very easy to put up. Surprisingly bright too! The warm white looks just like old school white string lights. The wire is light And I was able to tack it up in the windows with scotch tape. (It may not hold up for long, but with any luck it’ll make it through the holidays.) I’m not sure yet how long the batteries last (3 AA per string) but I will most likely switch these on when the sun goes down and switch them off when we go to bed to avoid keeping them on all night. Each window was easily bordered by one strand, though my windows are small, and larger windows may need more strands. The multi colored lights are really pretty too. All the old school multi-colored string lights I remember from my childhood were red, yellow, green and blue, but these have replaced the red with pink. It doesn’t bother me, but sometimes little details like that put people off, so I figured it was worth mentioning. I’m writing this review right after opening them and putting them up and am very very happy with them. I’ll update if that changes!Very bright light. The colors are more for spring time.I bought these to put in my front windows. They are very bright, with a good battery power. my rechargeable batteries would need to be changed every two days. While i own warm white lights that could go a week before changing the battery.(Keeping on 8-12 hours a day)There is no remote control.. it asked me to rate that in the review so FYI no remote in this if there is supposed to be one... BUT these are great I love them. I thought they might break easy but nope! They held up outside as well, I tried to make sure the battery pack wasn’t in a direct path of water and whatnot. The only downside is the shiny copper wire, which is honestly just a component of the product and might be chosen specifically for this feature but when I put it on my wreathes and such the wire was very very obvious. I didn’t mind it too much but my Xmas stuff would have looked a little better with it being less shiny. So not really a true complaint... oh and there’s a twinkle setting too!In the past I have used elwire to light up my bicycle, hat, costumes and tent. The problem with elwire is that you have to tape it to the areas you want it to hold and they tend to crap out easily, loosing light in areas and they have a noticeable buzzing to them.The copper wire on THESE lights is bendable, making them easy to attach to your bike or wrap around your body. They are VERY PRETTY and easy to wrap up for storage AND they don't get tangled.I have owned many different kinds of battery operated lights and these are by far my favorite, so far! I wish they didn't take three AA batteries, but I have owned some that take C batteries, so I can deal.I would recommend these to festival goers, or someone who needs them as a centerpiece for a party.I wouldn't recommend these to someone who wants to hang lights in their backyard or for nightly lighting. If you are looking for something like that: I would highly recommend solar or lights that plug in.Overall, I love these beautiful lights and I can't wait to use them for my next costume or bike ride!I try to leave the most accurate reviews possible and update my reviews if I experience any changes in my products. Purchase with confidence and let me know if you found my review helpful by clicking “yes” below. :) ♥ :)It does exactly as advertised but may not be suitable for outside use with the absence of absence of a timer for automatic shut off as well as being waterproof. If you need this for outside setting and want a no hassle having to go shut it off daily but it off daily this is not the product for you
