Let me start with the price...this was 25% less than I was quoted for re-covering the counter stools I already owned.  The fit of the components was very good (remember to use blue thread locker when assembling.)  The assembly was very easy.  Everything was included except a phillips screw driver and thread locker.  Surprisingly,  there was an extra bolt for each connection. There was also two extra pads for the feet for each chair.   Very nice!   The stools look really good and are very comfortable.  These stools are light, compared to what I had.  Time will tell how they wear.  Presently, I am delighted.
The only weak spot I see is the seats are attached with wood screws.  This may be a problem with normal use.
