Most of my rack is made up of BD gear. I’ve owned Metolius and Petzl before, but have since replaced my gear over the years with almost all BD equipment. The #4-#13 stopper set is great for everyday use on crags. I haven’t used the smaller numbered ones yet, but the #8-#11 are great for finger cracks and fit perfectly in anything to include the occasional off-width (which I also used them for before I bought the hexcentric set). My only complaint would really be the length of the wires. I’m not a fan of having to use up most of my 18cm quickdraws on these if you have to put it in the crack more than 3-4 inches. But, for the price, they’re worth it. I’ve had this set for more then a year and haven’t gone a climbing trip without using them all over it. Great for setting up bottom self-belay anchors when I climb by myself, or for the passive protection you need to rely on when it’s neccessary
