Their customer service is top notch. Mine is a second gen (they are now producing the 3rd)
The prototypes they sent around all over the world and corrected issues they found. Their product testing is also to the extreme. (standing on limb and twisting backwards, putting in oven then shooting, leaving in cold and shooting, left one outside for half a year then shot it ect.) Had sever tillering issues but fixed that
The first gens had a laminated riser which just curved around the grip, they found those separated and fixed the problem. Second gen (mine) goes through the whole riser and I have not had any issues with the bow at all.
30 year warranty when I bought mine although i hear something that they are lifetime now?
