Bought two sets July of 2018. One of the four spotlight was Dead on Arrival. Another one lasted one month. The remaining two still lights but it’s getting dimmer and dimmer by the day.
I’m sorry for the problem. Remember that you have a 90-day warranty from Touch of Eco.
Also, one thing I noticed is that if the solar panel isn’t getting enough sun, the rechargeable batteries don’t get fully charged and lights get dim.
