On my last order I purchased 4 mf bonnets 6.5 inch as it says so on the order recieipt, and today I decided to test them out.. but these BARELY fit over the 6.5 foam pad.. its soo soo tight and the pad is smushed inside of it.. did I recieve the wrong size bonnets? are they suppose to go on easier? i had to like squish the hell out of the foam pad to get it to fit inside of the bonnet.. and it doesnt spin around nicely because the foam pad is all squished..
