I purchased these lights to help with a dark driveway. My decision to purchase this product had mostly to do with the sturdiness. Out of 8 lights, 4 initially didn't work, although testing them beforehand there wasn't an issue.Reading through the reviews one reviewer mentioned adding am eraser top to the bottom stich.My solution is similar, a small cabinet door bumper. Worked perfectly.Time will tell on the longevity, hopefully they will last.
