For the money and what it can do, it's great.  Ok here's the bad part: the plastic seams tend to rip apart, especially if it's windy and you have the flaps open.  In fact, the entire thing will blow away in any wind.  I had to tie it down with tent pegs and then it stood up to some pretty fierce storms. I repaired the seams with duct tape. All that being said, I was able to squeak several more weeks out of my growing season and I'm excited to be able to start planting earlier in the Spring.
