I have had this little row cover  house  since last late winter. I had good luck  with lots of greens , now with i use the frame with a paper sun and bug protector and have planted and started in ground and in a tray my little fall crop. When it gets freezing will cover left over greens with the plastic zipped some and mulch, and will have a few greens all winter. The plastic a bit thin, but ok for small garden.
