5 and again was really anxious waiting for the sandals to arrive, but surprise, they fit perfectly! Perfect for those smaller / delicate areas that are harder to reach with a larger electric shaver. I spent time today a/b/c-ing it against an altec Lansing inmotion air and a pair of good floorstanders. The speakers are toward the ear canal and heard by anyone else. remember customer services is great 👍. 5, that fit but pinches my toes and gives calluses. 5, which I’m glad I did because they fit perfectly. Really good quality and how I love the colour! The instructions do not explain the the widths may need to be adjusted. Had to return after a week of use.
