I just redid my mask with their dual density poron kit. The padding is super comfortable, but I would recommend to proceed with caution with that particular foam kit because the poron is a very fragile foam and the velcro for the sweatband has already ripped it up in a few corners. As far as the company, they are extremely helpful and the finish of the kit is excellent. I don't think that you can go wrong with them and when I refurbish my other masks, I'll be using them again for sure.
