I have arthritis in both hands and find this hard to hold onto and hard to manipulate to reach back of teeth. Also have trouble. getting warm water, must use measuring cup and microwave to get tolerable temperature.
Have been using this Water Pic for a couple of weeks., Have one problem., the pic will sometimes comes unlocked and water squirts all over... I must recheck every time that it is locked in before using..
Happy with it's performance. Would prefer a larger water chamber, but that's a personal preference. It's great because it's compact. Perfect for taking in our RV. I would recommend it.
