The sunshade is easy to set-up and does a great job of shielding its occupants from the sun without baking them via the hothouse effect that some shelters cause. Mine is very durable and has lasted years. Buy the large, the meduim is too small to stand under. Here are the downsides. 1. it is a bit short, i think it is designed for sitting under. 2. The poles are a little on the weak side. Other than those two issues, it works great. I like the irregular design because that allows you to but it up against trees or other fixed objects.
