Would not buy again for full size bed. flat sheet way too small, fitted sheet may not fit after several washings. 
I bought a set of these sheets for a full size bed.  They claimed that it would fit a 15" and up mattress. 600 thread count. 
First the Pros:
Sheets are well made, very soft, good construction
Cons:
The fitted sheet barely fit my 13" mattress, probably within 4 or 5 washes it won't fit.
The flat sheet was totally too narrow.  If tucked in on one side the other side would be even with the top of the mattress.  The flat sheet, in order to fit properly would need another 8"-10" of width.  Fortunately I have a queen size bed and extra sheets that I can use.
Would not buy again.
