Terrific!
A great purchase.  These crutches are sturdy and well made.  They are easy to adjust and have knurled adjustments at the top and bottom that keep them tight and eliminate clunks and rattles.  They also telescope down to about 2.5 feet in length when not in use, which is very convenient for keeping them out of the way in restaurants or for plane travel.  As noted by others, the hand grips are firmer than standard crutches.
