I got an underdrive pulley for a lower cost. It did have a small improvement of performance but primarily when te AC is on when you notice it the most. If i could do it over i would have got a performance harmonic balancer as i think my underdrive pulley made the rest of the accesories deteriorate faster then normal. You do get more power but it aint worth it. BTW i still have it on( 2 years) and everything is working correctly

for $400 , it better be a Titan Motorsports one. Seriously and its far superior than the OEm one.
If you can, locate a used OEm one which you can buy for 50 - 100 dollars.
Also do not spend money on the Underdrive crank dampners that you can buy all over for cheap or with pulley sets. Your crank will not like it in the future due to not being properly balanced.

well on my mk4 i heard this nasty screech, I didn't know what it was until i did the timing belt and the front part of the pulley piece fell off.
the rubber usually rots and the pulley piece gives. On my other crank I had a spider crack all the way up the harmonic balancer

You def want to listen to everybody. Those cheap underdrive crankshaft pulleys are bad for the motor.
After I put a hard 10k miles on my GS3 the original pulley broke (btw it made that screeching sound like zazzn said) so I installed an ebay underdrive crank pulley. Two weeks later I was doing some donuts, which I've done plenty of times before (I know, foolish), and on the way to my girlfriend's house the car started making a knocking sound like I spun a connecting rod bearing then it got so bad it cut off while I was on the side of the highway. Now I need to get a new motor. Lesson learned!
I know the donuts probably made it worse by g-forces pulling the oil to the side of the motor and off of the crank but as added insurance I'm not doing another cheap crank pulley/harmonic balancer.
