The reviews here are quite amusing:

"I never could find a condom to fit over my unusually large 16 inch penis and with a girth of 8 inches, most condoms are too tight, cutting off my circulation, my girlfriend kathy just loves the feel, well we're both in ecstacy, Im in line with the other guys on this, Durex xxxl are greaaat"
"They are the only ones i have found that fit at all and only break if i go too fast. i am 13 3/4" in length and VERY wide (8" around in middle but +9" around at the base) so it still doesn't cover all of it, but it doesn't matter since i haven't found a girl who wants to have my whole thing in her anyway and the widest part is lower than the condom will cover too.
Two reasons i don't give it 5 stars are that the reservoir at the tip needs to be bigger and the name needs to be different. its embarrassing for a 16yo guy like me to buy a condom named "XXL". but it's better than not having any condoms i guess."
"i am a hispanic man and finally i found the right size condom. thanks for your product being cater to the bigger size. i am 11 1/2 inches long and 8 inches wide. my girl friend is very pleased,i was always worried about breakage which happen all the time. thank you."
"I am a white male with a 23 inch penis, and 10 inches in diameter so this does not fit me. So I cut a hole in one and staple them together it works great. Before this I was using plastic shopping bags, thanks durex."
