I use about 16 of these as markers on my long driveway- the disks are sturdy and appear to be capable of resisting normal abuse and weather. However I have noticed two issues which are disappointing given that they are not inexpensive. First, these lights appear to need more battery capacity as they typically have a duration for less than 6 hours. In colder weather they appear to last significantly less (3+ hours) Obviously light duration will vary with many factors, so your mileage may vary. But as a comparison, my other solar lights (path lights and spotlights) do consistently last longer. After one hard rain, I noticed one night that 8 of my 16 disks were not lighting. So I banged the back of the casing of each of those and then they all lighted. Since then, I have noticed this issue much less frequently. Nonetheless, temperature or humidity variables may affect their ability to light.

They look really good when lit up. We do have 1 out of 4 that is fully exposed to the sun yet stops working soon after dark. The other 3 stay well lit. They start to go dim around 5:00-6:00 am. We when you unpack them they feel very sturdy.

I like the lights but am mystified how this light broke.

UPDATE: I ended up contacting the company directly. They told me not to return my original order. They said the one light that isn't working is a battery defect. They are sending me a replacement. There's actually 4 lights on the steps (see photo). One light is defective. I contacted Amazon and Customer Service gave me the option to refund or replace. I chose to replace. So, now I have to box up all of the lights and ship them back while I wait on my replacement box to arrive. That's a hassle for one defective light, in my opinion. This is the first time I've been disappointed with Amazon Customer Service. That said, the lights themselves are okay. They look brighter in my photo than they are in person. They're acceptable for what I need. If you're looking for bright lights, for safety, these aren't the best lights.

I use these to mark my gently curving driveway when backing out at night, which I mostly do in the early morning. Unfortunately, they don’t stay lit throughout the entire winter night. But they have held up in the cold and rain and I’m pretty sure at least on delivery driver scored a direct hit. But they still work.

Easy to install, they are lights, nothing special to write home about.

This seemed like it would be a great product but it's just a gimmick. This is your bog standard cheap LED fixture housed in a puck to go on your driveway. I have cheaper fixtures that provide more light and that are way more useful. One out of the 8 that I purchased for $100 one was defective and these have a really cheap feel to them that makes me reluctant to drill holes in my driveway only for them to fail after a season or two. I was expecting a high quality aluminum product but these seem to be more plastic than metal. I seriously doubt they would survive being run over. They appeared to be round in the photos but they are actually a very ugly oval shaped device that looks extremely cheap. I ended up returning them. They cheapened the look of my driveway more than they enhanced it especially with the dim but blue white LED's. These have the look of the cheapest dim LED bulbs out there.

Had several of these lights crack after a car/light truck ran over them. Once cracked, water infiltrated the lights. Lights were only a couple months old and returned for replacement. This time I will place them on the grass instead of driveway. Other than that, the lights stay illuminated most of the night, but as days (sunlight) grows longer, I would expect them to last until sunrise.

I would have like to have all 4 lights work.

Beautiful lights, only after a month the batteries do not hold light for a long time. I installed it on the dock near the boat in April, in May one lamp at 12 at night was no longer on, given that it turned on at about 8 pm. And right now, at the end of May, they turn on at about 9pm and by 11pm 3 lights are slowly turned off.
