I was surprised to see how great the quality of the suspenders were. The clasps take quite a bit of force to open (which makes for a fussy toddler sitting there forever while mommy plays with the mechanism), but they close down and lock into place where they stay exactly right, so I am willing to deal with the slightly challenging clasp. The size adjustments are similar. There is the open position where you can adjust it, and then you squeeze it shut to lock it into place. They look great and they will fit my 1.5 year old for plenty of time. I am happy with the purchase, and I am happy that my son will look adorable in little outfit (while his pants stay in place).
