At first I thought the duvet cover set was alright. Very thin material, but it would do the job. Then I tried the zipper. I took me 20 minutes to get the zipper opened. The space between the zipper and fabric is about one mm wide,  which means it gets caught on the fabric each time  you are trying to either zip the duvet cover on or off. I found this incredibly frustrating and have decided to look for a duvet cover set that has buttons instead. Not worth the effort. Buyer beware.
