Obviously there are lots of different versions/build's of these, I must of been lucky for mine to last 3 years and it gets lots of rain etc , quite exposed site. I did actually seal the glass window with silicone sealant when I first installed it as the inside of the glass was showing a little condensation build up, so maybe that's why it's lasted :/
Bought one last year lasted 3 months .garbage bins all over uk must be full of them just saying
I've got a different brand solar powered light from Amazon, had it about three years now. It's positioned over front door area and solar panel is positioned about 6 feet away on facia boards facing in a westerly direction. It comes on about a dozen times each night usually triggered by cats. Never had a problem with it, works 12 months of the year!
Problem with these is , it's winter when you most need it.But as the nights get longer it wont charge enough to power.
Sorry but these have been on sale for a long time now at this price. Being sola Light output is equivalent to 4 candles and if it comes on several times you will be down to match light 💡. Sorry
