While I love these, I much prefer the ones that are USB rechargeable. However, the quality of these is excellent and the only thing different is they require 3 AAA batteries. Now, there are times that would be more convenient, such as camping, backpacking, hiking, etc. So, if you are looking for a motion sensor, quality light that will provide good illumination, but you won't have accessibility to power, I recommend these. For a more permanent solution, it does come with double sided sticky tape to mount to the bracket, or it has hooks that can be mounted with included hardware. Then you just slip the light out of the bracket to change the batteries. It has an auto, off and on feature, so it adapts to your needs easily.
