Just like the more expensive rechargeable version
When I first got this I thought it was going to be a weak version of its rechargeable cousin but boy I was wrong!  Performs just like the more expensive rechargeable and without needed a charging base sitting out on the counter.  I bought this wanting something I could travel with.  The only thing missing in my opinion is a travel case.  I also have the rechargeable version although I haven't checked to see if the case that came with that will work with this unit.<br /><br />The replacement brush heads for the rechargeable unit work interchangeably with this one so that's a bonus.  I did take note of what other reviewers said about the battery compartment allowing water to leak in so each time I change batteries I take a cheap lip balm and rub it over the rubber o-ring for a better seal.<br /><br />In my experience a fresh set of alkalines last well over two months with daily use.  I haven't tried rechargeable batteries but suspect they won't last as long due to the lower voltage.
