Review (3/5): tastes like used plastic
...but other than that, and the fact that it really obstructs the faucet, it's a pretty cool little tool, and I'm still using it when I can't get to the better irrigator in the other bathroom, though I grumble about the awkwardness of the part that hangs down from the faucet, and about the off taste of the water that comes through the irrigator. My spouse won't use it for that reason. I think they must've manufactured it using recycled plastic, and that doesn't seem like a good idea for something that goes into your mouth. It tastes like old detergent bottles and, frankly, a bit like garbage. I have to rinse my mouth out a lot after using it. I wish they'd make it with good quality materials and then it'd be winner.
