I've purchased sheets from your site before and have been very happy with them.  However, this set is not very good.  The material is very thin.  I'm not sure how long they would hold up before tearing.  Also, the fitted sheet doesn't fit over the mattress as it should.  It pops off every night.  You don't get a snug fit.  The top sheet and pillow cases are fine.  I'd give the set 2 or 3 stars just because of the material.  If you have a thicker mattress these will not work for you.  They are made for a less expensive thin mattress.
