The produce seems fine, the top piece had a crack and I requested a replacement part but haven't received it yet. Update: After putting it together and putting in the shelf I noticed that the threaded peg that attaches to the side for the shelf is missing. It didn't fall out but was never installed by the manufacture. This unit is ok, but if I knew I was going to have these issues I wouldn't have purchased it. It took a phone call to Wayfair to get my replacement top that was cracked in shipping. I had requested a replacement online, never received a confirmation email. I waited a week then submitted another request on the website and no response. I finally called Wayfair and was told they could see both of my requests but they were never processed. The customer service rep was able to get the request processed and my replacement part is on the way. I am not happy with the manufacture of these Greenhouse. I wouldn't purchase it again. I will probably live with the missing piece or see if I can purchase one at my local hardware store. It's easier than trying to get a replacement part from Wayfair. I will be rethinking any future purchases at Wayfair.
