This is NOT FANTASTIC. It's a terrible product. It seems great in theory. I'm one of the original backers from Kickstarter. I had so much hope for their product and I waited over 5 years to receive it. Well I followed the instructions, plugged it in for the first time, and it's leaking EVERYWHERE. The smaller flosser mouth piece is the only one that fits my mouth and it doesn't fit or click into the unit properly, and it literally BLASTED off of the unit and hit me in the face. Everything leaks and this is terrible. Like it's BRAND NEW I literally JUST took the thing out of the box to try it today and I got blasted in the face with water multiple times, had to wipe up water from the floor multiple times, and it was just overall NOT A PLEASANT EXPERIENCE. I emailed customer support, I hope they give me a full refund for this crap.
