In the Weber 6523 base, which looks like a spider, after a while the pads/rubber feet of the legs break and the legs start to open, resulting in the base cracking.

It is suitable for soil, lawn, or gravel tiles, otherwise you have to be careful and when you see the legs slipping, change the rubber feet.

I saved mine, but a friend's cracked. I wouldn't buy it again. I'm not referring to the Weber 6526 base, which has wheels, for some reason it is in the same category.
