[Q]: I was extremely disappointed with the fabric and color when it came. It is obvious that it is of poor quality but I guess you get what you paid for 10 bucks.The zipper of the plastic cover of one set was broken.I bought 2 queen sheets and I wanted to return both purchases if only I did not have to pay for shipping.Do not buy this!!!! You will regret it.
[A]: Negative


[Q]: As a student of jiujitsu i understood alot of the moves but i found that without previous knowledge these pictures and instructions were difficult to understand. I feel there is alot of good information but not worth buying.

[Q]: It was a bit confusing to assemble. Had to redo a few times before I got the right rods with the right utensils. In the end you get what you paid for - bottom of the line product for cheap.
