"well, it is a $250 engine, and it performs almost as well as a Polarstar jack id say, with the reight tuning i can imagine it would preform the same, if not better.

pros:
dirt cheap for a hpa engine
looks awsome
comes with all the parts needed
programable fire modes using the selector / trigger

cons:
you dont have one :(
newer engine so its not been super time tested

overall, i think its an awesome product for someone who might be on a tighter budget. definitely a fun engine and i see much success in this product
