I got these because we were going on a trip driving across the states. We all had different types of toothbrushes and these fit every last one of them. They were not hard to open like a lot of them become. I like they had like a breather type hole so it can still drip the water out of them. If we stay in hotels like we did I don't like for the brush part to touch the sink. The different colors help too because it help distinguish from other family members brushes so we aren't using each other's.
