You may want to use different anchors but otherwise it's a good value.
I bought this as a gift for someone. They had no problems setting it up, although they opted to skip the included anchors, which seemed pretty small. They made their own out of steel rebar. So far it's held up to some pretty high winds with no issues. It's nice and roomy and will give them plenty of usable space for their garden.

not just for plants.
Not just for plants! I have used this greenhouse as a gathering spot during Covid times. It has worked out wonderfully! I read all of the reviews about it not standing up to win very well, so I bought some very inexpensive cinderblocks and ratchet straps to hold it down. We have had some EXTREMELY windy storms of late. It held up just fine. It took me many, many hours to put the frame together. However, with the use of some chairs to prop things up, I was able to do it on my own. I had one friend help me put the plastic over the frame. It is a wonderful, cozy little gathering spot.

Made it a little better
I love my new greenhouse. Amazing product!! I added a little height to make it look better and planted some flowers around it.

Shipping was very fast. Box in good shape. Instructions hard to understand. Finished product is good. But took a few trays on the frame. I like it.
