These lights do appear to be durable. My initial order had one unit that only lit up 2 of the 3 LEDs on one side. Returned and received a prompt replacement. First one out of the new box, only 2 LEDs lit on one side, plus what looks to be white paint on the lens over the nonworking LED. For the price I expect them all to work. Still deciding if I want to do a second return or refund and buy from a different vendor.Other than that the units seem to be built well and the lights aren’t too bright.
