Strengths: Fairly light, simple, easy install.
Weaknesses: A little noisy.
A good guide for the money: cheap, light, and installs pretty easily with provided spacers. Design won't bend your ISCG tabs if you 50/50 something pretty hard. The pulley wore out after a few months of pretty heavy use. However, FSA has replacement pulley and hardward kits available.
