Good brushes with some flaws
I bought two of this for traveling purpose, one for me and one for my wife.  They were convenient because they used regular AA batteries that were available anywhere in the world.  We did not have to worry about bring a charger.  We use the rechargeable Sonicare at home, so we want tooth brushes that mimic the same while traveling.  However, we missed the programmed feature that our rechargeable unit had, i.e. it hesitate slightly every 30 seconds during the two minute cycle to prompt us to change brushing surfaces.  This one went for straight two minutes, so we had to guesstimate when to change the teeth surface that we were cleaning.  Also, both the two we owned had big problem with the battery covers.  Neither one was able to snap close completely, leaving a gap for water to possibly getting in.  Bad design on this part.
