The greenhouse went together fairly easy. Took two of us about 6 hours to put together including leveling the ground. Directions could use some work to make parts clearer. For those getting this greenhouse, remember to remove the protective plastic covering from both sides (white plastic one side and clear plastic on the other) of the window panels. Make sure to use a level and a square on the base parts. Make sure you turn the cams to lock them and install all the bracing. The greenhouse ended up very sturdy after putting all together. Thanks for a very nice product.

I was pleasantly surprised how nice this is for the money I paid. The directions could have been better. If you’re up for a challenge of putting it together this is for you. The were lots of pieces but it’s worth it.

The greenhouse was very easy to assemble. And it seems to be sealed up very good. We put it up against the back of our house to cover an egress. It worked perfectly and looks fantastic.

We are very impressed with the quality of the greenhouse! It is very sturdy and has good insulation. It definitely is a two person job to assemble, but once you have a grasp on how to interpret the instructions it goes fairly smoothly. It has already survived a couple of windstorms with no damage. Here’s a couple things that will make it last longer/work better:-peel the covering off the panels before you assemble it-anchor it securely to the ground-seal the panels/gutters with a clear silicone caulk. This will help with insulation, as well as keep the panels more securely in place.-line the base with a tarp, and then cover said tarp with gravel/pavers. This will help with ground insulation and also make it look more put together

That I so exciting the quality was so much betterthen I had expected for the price. Item was exactly as described and packaged very well for shipping.I'm almost done putting together, so we'll see how long it lasts when I get it in the yard.This one looks top of the line for cultivating David Austin rose seedlings by cuttings.

Fairly easy to put together. As other reviewers noted, you'll likely end up with some extra parts, but the end-product is very stable. Once finished, you can easily pick it up and put it where you wish. Highly recommend.
