I have had these raised garden beds for 2 seasons. I purchased 4 of them. They have lasted through extreme heat, rains, Ice, snow, wind and even large branches from trees falling on them. They haven't been damaged or warped in any way. I expect to get years out of these which makes me happy because I see my neighbors wooden beds rot and fall apart after one season. Its better to buy a quality product and have it longer than not. Very pleased with these. The covers are convenient going into fall in zone 7b where frost is inevitable in October. Keeps my spinach and kale lasting a month longer than without it. i also have the screen covers with them which helps keep most of the bugs out.
