Good for only a few months.

Worked OK for the first 2-3 months. They were white when I first purchased but after 6 months, they are all yellow. The solar panels also appear to be melting or deforming. Finally after two years, they are no longer usable and I have to replace them all. I did try replacing the batteries several times. The materials are very cheap and flimsy where I am sometimes able to tap the item and they might just work.
