Returned before I even installed it! I read all the reviews on here before I purchased this, and they were very helpful in making the choice of this cap. I wanted to use it to light the single post at the end of our driveway, because driving home on a winter’s night it is nearly impossible to see the entrance.It did appear to be bright enough for my needs, but what they don’t tell you in the description is that you are not supposed to use this during winter months. It says in the instructions to remove it during the winter, meaning I have no use for this at all. This probably does not affect those who are using it on a deck or fence, but I think it’s a total waste to have something you can’t leave out there year-round.Other comments: The plastic housing is really cheap. The solar panel was cracked when it arrived, although it did not appear to be a result of shipping. It does not mount permanently to the post, could be easily knocked off (or stolen in my case). Once you pull that tag that reveals the batteries, you cannot turn the light off. Even if I had decided to keep it and install in the spring, I would have had to take out the batteries to turn it off until then. Screws are difficult to unscrew because of placement and the cheapness of the plastic they screw into. I imagine that if you took this apart more than a few times, you would not be able to tighten the screws at all.I am disappointed! I really wanted this to work.The only good thing is that it did arrive quickly, even though I did use Free shipping.
