Question: can I replace the battery in them
Document: The Solar battery is very inefficient. I feel I wasted my money. It will remain in the box until I figure out what to do with it.
I like these because they are battery operated and I can put them in a vase anywhere in the house to add that special something or to add light to a room
This are bright and the solar battery is long lasting. On a sunny day they will last all night. They even charge on cloudy days but only last a few hours then..
I put these on my railing fresh out of the package and waited until after a full day of sun to charge the battery. They have been on my railing 3 days and nothing. I even went outside 3 times to make sure I had it turned on and of course I did. I use solar lights every year and understand how they work. I wish these would work because they would be beautiful. Not worth the time to send back.
These lights are a great purple color! We're planning on using them for wedding decorations. I don't know if I would put them outside since the rubber gasket did not seem to be placed correctly (i.e. water might get inside). The built-in rechargeable battery was precharged and lasted for at least 4 hours (I have not performed a full-length test, yet). The flower parts are made of a soft translucent rubbery material, so those seem quite durable.
I was looking for a tree to replace one that was stolen off of my daughters grave. They don't sell the flower tree like I had, so I thought I would order these purple lights and put them on a tree of some kind. They are beautiful, they can blink or they can be steady. They are made of a rubbery material not the hard plastic like they are usually made of. I love them!!
I may try another time as they were so cool looking.
Did as advertised, is very pretty will be getting more like this if you like purple you will love it  I do
I have yanked the crap out of our Christmas lights for years, and they've held up just fine.
I gave this to a friend as a gift and it looks beautiful by her spa. She is very happy with the lights.
