Boom. A fatboy a slim adjustable and I don't know what the third one is... help if you wish for $15. Pretty happy. Getting a hose clamp and some wire today to fix the casing on the fatboy. Kinda Gunky but scrubbing bubbles has loosened a lot and I'm going to be throwing them in the jewelry polisher soon. What is the non adjustable on the left most... I'm sure someone knows?
