can be frustrating first couple of uses.  Stay with it; patience
Once, I kept my fingers away from the two buttons (on /off & speed) I was much better with the process.  I love that I can use it in the shower.  Haven't traveled with it yet but plan to bring with me when I do.  I found the water amount sufficient to floss entire mouth.  Have used for a week without any recharge needed.  No surprises, was pleased and satisfied with what I purchased.  Judy
