I have a few gems:

- 9.8 dropper. Went through 4 warranty replacements before I gave up. 

- SID fork with lockout. The lockout was hydraulic and if if came off, which was a common occurrence, it's dafault position was full lockout. 

- Never bought a reverb but every time it came on a new bike they with never ceased to disappoint. Now I just take them off and sell them right away. The last one I sold for $175 unused. They retail for like $500-600.
