The Good: Light works Great and quiet. easy to install
The Bad: the Poly is mounted on the taco so if the taco got broken you lost your chain device :-\
I had this chain-Device for almost 6 months... it did a great job until it had a few rocks in the taco.
the eyelet that holds itTogether just snap and was holding there only with the pressure of the nut.
after a ride on some rocky terrain i started to hear my chain rattling and when i got down i saw that the taco and poly where M.I.A
the upper skid is very touchy to pressure if you are Fastening the bolt little to much it's starts to crack.
I just got the MRP Micro and i notice that the Materials is different and much better.
so i guess that in the G3 they also improved the Upper Skid.
Overall a Good, but very Fragile Chain Device. if you are looking for more bling then durability it's a good choice.
