This is a review written when the lights were still new. I may have to update depending on how well they charge later. I really like these. 48 ft is a generous length and they have a blinking function as well as a slow on off function. This is an addition to the always on at night. The lights themselves are plastic. Despite that, they look extremely classy. They give a nice warm light. It illuminates but is not glaring. I'm not sure how hard it would be to completely straighten out the wires, but as I was putting them on the trees it seemed like it would be possible to do. For my application I was trying to zigzag them between trees on either side of some stairs. We have outdoors so I didn't need them to be straightened out. Each bulb has a little hook on it. I found this to be extremely handy and I really enjoyed it. It made installation a breeze. I could just clip the hook to a handy spot on a tree and it stayed on really well right where I put it. We'll see how it holds up when it gets windy. I did leave slack between bulbs though. The solar panel seems large. It has two options which is to put it in the ground with the spike that's included or you put the clip on it to clip it to something higher up. I opted for the clip. You can also tighten the screw to have it hold the angle that you set it at. One concern I do have is whether it will be able to fall off the clip since it was just a friction fit. This hasn't happened yet though. You can charge it inside as well. It has some indicators on the back to tell you if it's done charging. The indicator lights go from 25 to 100% and they blink at the level that the panel is charging at. I decided to charge them up completely inside before putting them outside when it was dark so I could easily see where I wanted to put them so that the path would be illuminated. This seemed to work well. I am curious about how much light the panel will require to power them during the night though. I also really like that these are connectable to another set. I'm so impressed with them that I'm planning to get another string to continue the path way. Our house has an extremely steep backyard and stairs are the only way to get to the flat part at the bottom. We've only just now gotten around to lighting it up and solar is the best option since there's no power there. I am hoping these are the solution to this issue. So far so good!
