I bought these pajamas as a present for my husband. He has worn them several times now and I have washed them once.
My husbands report and my observations of the product are:

They are extremely comfortable, the material is silky, cool, and smooth.
They are true to size. I bought them for my husband in his normal size range and they fit him perfectly.
The product seems to wash very well. It did not shrink or twist in the dryer. Also, if you hang them up after they come out of the dryer they will not get wrinkly!
The color represented on-screen seems accurate. The color I received was exactly what I was expecting. [However all monitors are different]

All in all, they do not look or feel cheap. Although, I'm sure you can find much more expensive and luxurious sets, you will pay quadruple the price! For this price, I am very happy and I will probably buy him another set next Christmas because he loves them so much!
