This has been excellent!!  A June dip into/under 32° one night and this saved my plants!!  Only issue I seem to have is that there's not enough ways or ties to hook the plastic securely into place so it has to be adjusted often....and that's super easy but annoying since any breeze will rearrange it.  Fits the frame, heavy plastic, easy to put together for one person so it's a 5-star for me and I hope I can find more and in different sizes.
