The Good: easy to work on for the most part, can fix it with childs toys and is really kinda crazy haha
The Bad: well when i got it i didnt really know much about it because i hadnt really researched it because i was gonna go get an expensive wheel with a khe freecoaster laced to some gsport rim, but then i saw how cheap it was on albes and immediately bought it instead. biiig mistake because i was dumb. it worked really well for the first month or two and then it started not engaging and i mustve smashed my nuts and knees a billion times. so i took it apart and the springs were soo broken. haha so the bad, springs break, otherwise good.
all the stuff i said above haha and then i mean i read on a bmx forum that you can take wind up toy springs and rebuild it using those. so i ripped apart a few wind up cars and found a few wide enough ones but they were still too thin so i decided to fold them a few times and then i bent them like this /_\ and the first few layers are what gave the clutch tension and made it able to engage and the next three or so gave it room to keep from breaking. so far it has worked great. i am happy it finally works really haha it makes me better at using a cassette. haha
