Have learnt from painful experience that you need to secure them very well. If you can bury the bottom of the plastic in the earth that helps. If its on hard standing I have resorted to fixing ground bolts to the concrete and tying to the frame.
The frames wont take a huge battering but generally if a few measures are taken to secure them they do pretty well.
I have 2 types one is the Gardman which has a great frame but the cover is very fragile, Gardman will replace the covers if they rip though.
The other is from FeelGood UK, they do various types to suit all budgets, I bought the budget variety, the frame is a little flimsy but the cover is great.
With both types be careful with the zips as they can rip too.
Nowhere near as good as a glass greenhouse but easy to move and you dont need a proper base.
