I had two of the original Joplin droppers and had zero issues with them during "normal" use. Eventually I had an oil leak, but it was the 2nd or 3rd season in. At the time that was pretty solid reliability. I recall droppers shitting the bed in the first couple months at that phase in their development.
Back when I was riding clipless [Gasp!] I had a bunch of eggbeaters in the fleet. They worked great and were easy to maintain.
I've had a bunch of their multi-tools and not had any complaints.
I never warmed up to CB's wheels, but then I have rarely had an interest in complete wheels generally preferring to buy hubs and rims then build locally. More choice and fewer proprietary oddball parts to deal with.
Any way I'm glad to see they are doing well. I don't run into much CB stuff in my little slice of the MTB world so it was not obvious to me that they'd remained successful.
