Review:
This is an awsome product. I was lucky enough as a shocker owner to get on the preorder list and ensure that i got one of the few shocker frames that the company said they wouild make. RIght out of the box i was amazed. The frame came with a full set of replacment screws for the frame and special allen wrench to adjust the set screw that taps the micro switch. The instructions sent with the frame were easy to follow. When first setting it up i encoutered a slight problem with the set screw that hits the microswitch in that it was pushed too far out. I was unable to adjust the screw via the convieiently located hole in the trigger (for extrernal adjustment), so i had a look over at www.impulseownersgroup.com . sure enough, one of the makers of the frame had a solution, they had put a little too much loctite on the screw so it was nesseccary to remove it with a wrench, clear the loctite out with the provided allen wrench, and then use one of the conveiniently sent replcement screws. A simple solution to the problem...After i fixed the minor problem, it was extremely easy to adjust my frame to a tiny trigger pull using their instructions. I must say that the customer service was impecable, Josh, the owner, is easly reachable by phone or email. adjusting the frame is easy. All that is nessecary is loosen the pretravel all the way, adjust the posttravel/magnetic power to the desired tension, attach the frame, move the microswitch set screw up against the post-travel, and then tighten up the pull to the desired length. the ability to adujust the pretravel and micrositch screw externall makes it very easy to achieve the deired pull length without removing the frame.
Conclusion:
This product is absolutly amazing. The ease of use, comfort and adjustability of the frame go above and beyond the call of duty.
