Customers say

Customers find the greenhouse works well for gardening and appreciate its size. However, the frame durability receives mixed feedback, with some finding it strong while others report it falling apart. Assembly experiences are mixed, with some finding it easy to put together while others struggle with challenging instructions. Moreover, the zipper quality is problematic, with customers reporting weak mechanisms and doors that don’t close properly. Additionally, customers report issues with fit, particularly with the cover not aligning with the frame, and concerns about water retention, with one customer noting water pooling in the top hoops during rain. Value for money is also mixed, with some considering it a good product for the price while others find it not worth the cost.
