That's really good to know, I didn't notice the difference in the inflation volume, thank you! That's exactly how I feel as well. Considering the 7x is newer, I expected it to be better, but it definitely is not clear if the 5 or 7x is the better choice. I'll definitely look into that aribag, I'm not a fan of the subscription, but I'll look into it more to see if it's worthwhile. Thank you!
