I tore my ACL 6 weeks ago and am getting a brace for both knees. I have a perscription for a CTi2 for my bad knee, my insurace will only cover 70% and that is if they cover it at all, my cost $507 or $1700 if insurace dosen't cover and I would have to buy a Asterik for my good knee $300. Is one Cti2 worth the extra $260, is it that much better? Or should I just order two Asteriks?
