5, I would order that. The timer on one dryer does not work. It?s kinda weird that there is 4 versions of every color except pink and red. This manufacture makes great shoes, I question the seller! Battery seems fine, printed manual text too small and mousy English. I ordered a small the first time and ordered another small and these must be an extra small. Wasnt a fan of the regular Ugg bot style, but these look great on my feet. I am going to go back and order them in black. Overall, a good buy. I should preface this by saying that I have always enjoyed Sony products - from previous high-end headphones to their TVs.
