Seems a bit big
It's great to have a footprint to extend the life of your tent, but this one doesn't seem to fit well. The actual materiel is the right size, but the metal rings for sticking the tent poles in seem to be too far out to be that useful. They are attached to elastic loops and extend further out than those on the fly or inner tent. Effectively the poles don't hold the ground sheet down, it's just the weight of the tent. Perhaps this is more useful when just doing a fly pitch. Still, it doesn't make the ground sheet useless, but I can't quite work out why it was designed like this, hence four stars.
