Is the Flak Jak chest protector good quality?

I need a new chest protector because my Leatt adventure does not fit with my fox chest protector. I saw that a Flak Jak IMS of LT IMS fits with the leatt. Are these chest protectors good quality? I can get one for $60 because I am sponsored so money doesn't matter. What other chest protectors fit with a leatt. Thanks I will pick a best answer.
