Does a good job blasting particles from between my teeth. Feels good on gums. No issues with the waterpik. I’m a dedicated flosser & don’t use this near as often as I thought I would. I don’t have extra counter space for it to hang out on so it goes under the cabinet. It’s faster to floss than pull the thing out, fill the water, plug it in, blast my teeth, drain the thing (don’t like mold), wrap the cord, shove it back under the sink, & wipedown the splashed countertop. It’s just a whole process that makes this a waste of money. Know what you’re going to do with it. It’s a good product if it’s easily accessible.
