I would not recommend them. They really don't add HP, just relieve some HP by turning the accessories slower. This may cause problems like increased steering effort, lower alternator output, overheating in high temps, and lower output from you A/C system. This is all due to the slower turning accessories (water pump, alternator, a/c compressor and power steering pump).

This has been discussed here before. Maybe run a search to see what others had to say.

i have read a few of the threads about them, i was just curious about thoughts on those ones.
but, meh, i dont think i will go after a set.
i dont think they look super quality, and i dont want to spend 90+ for a nicer looking set.

Ah ok. I misunderstood you then. Yeah, my initial impression was that it was a hack job on a lathe. One thing is for sure when talking about serpentine setups, the grooves have to be fairly precise to not cause wear problems with the belt.
