Very premature review, but still wanted to give my thoughts, as I've had a few other solar lights from Amazon in the past and so far these have impressed me the most. I can only speak on construction and not weatherproofing or longevity. What I have learned is you really need to have as much sunlight as possible, and good batteries. I think I have spent more on batteries than I have the actual housing units! With that said, I live in Seattle and do not get a whole lot of direct sunlight, so I'm not being too optimistic, especially considering I bought these in February, but really liking these so far. They give an awesome looking ambient lighting. They are very white, the photos attached make them look a little more natural white but they're not yellow in the least bit, they are pure white LEDs, and that's exactly what I wanted. I have not replaced the batteries yet, mostly because I didn't feel like unscrewing them all, but also I wanted to give the batteries that came with it a fair shot. I expect I will want to replace the batteries at some point but we'll see. Typically these types of lights don't come with the best batteries and in the past I have replaced built-in batteries with larger/better performing ones.I am a bit concerned about durability considering these are pretty much at ground level. I didn't put them completely flush with the ground but they are only sitting barely above the ground. Construction on these is by far superior to any of the others I've had that were plastic. Love that they are metal, however I've never had ground lights like this before so I'm hoping they survive heavy rain and sometimes flooding. My only "complaint" is that they look a bit ridiculous during the daylight. They look like metal flying saucers in my yard. I almost wish they were black so they would be less noticeable, but they do look cool nonetheless.Putting them together was extremely easy, though the base that you put together and attach and shove in the ground isn't the most sturdy, it will do its job. I put a fair amount of pressure when putting these into the ground and never once did I question the integrity of the lights or the base.There are photos on here of these lights sitting on stairs, etc. I don't quite know how that would work as they wouldn't be attached to the ground in any way? What if people kick them around? Animals? Wind? I don't recommend buying these for that application unless you have a way of securing them down that I'm not aware. These are good for putting in gardens that get a lot of light during the day, or short grass.I do expect these will collect dirt and will need to be cleaned regularly, but they're on the ground so duh. Just hoping it doesn't affect the light or charging ability too much if I'm not out there daily wiping them off, you know?Update: Have had these a few months now. Lights still function well. They all still work. I put them in areas where the sun hits differently, and plants are starting to grow in, so there are a couple lights that don't get sun. If they don't get DIRECT sunlight during the day they won't work and if they do work it won't be for very long. The ones that get the most sunlight last throughout the night, which is great. I've actually decided to order another package of these. For the price, these look great. The only downside is I've noticed they have started to rust on top. Doesn't look amazing during the day, but it's not a huge deal.
