I am going to be devils advocate here... You are sure you put it on the right way around? If you put on the wrong way, it is impossible to roll down. Writing a product off in this manner is not really the purpose of the forums. If you think the product is still faulty... Then contact lh for a refund.
I'm sure that customer services will be able to give you an exchange or refund if you're unhappy with your product.
Make sure you leave a review on the product page too, it's always helpful to have people's opinions :)
We don't use condoms so I can't recommend anything myself, but hopefully you'll find something. Customer services are usually great for recommending products. You can contact them by email or I prefer using the love chat.
Welcome to the forums, I hope you find a solution :)
