These pillow inserts are quite adequate.  They are very well priced so that is a big factor, especially when you have to buy several as I did.  They are so very stuffed that it was actually a slight challenge to get them into the cushion covers so that the pillow corners get all the way into the corners of the cases.  That said, they do settle a bit over time and fill the pillows in better.  I would say that price wise they are a very good buy so I would most likely buy them again based on that factor but I do not find them as comfortable as I would like because they are hard, and they do not really relax at all as you lay against them.  In the future, I might choose a pillow with a slightly lower thickness if that was available.  However, the pillow inserts are as described so I can't exactly fault them for that.  And, in case this is a factor for anyone, these pillow inserts do not have a real fabric shell so they can only be used as inserts.
