Not horrible but I'd pass.
Well it isn't the best or the worst, but I wouldn't buy it again or recommend it. The setup was a nightmare, and the directions (printed in haphazard English) were nonsensical and unhelpful. The waterpix pressure is REALLY intense; (regardless of the setting.) It actually made my boyfriend's gums bleed; (and he is a daily flosser.) It also made my tonsil bleed! Be VERY careful when using the waterpix. The toothbrush is pretty good, it works well. My BIGGEST gripe with this product is when you use the water pix you have to supply the water source, it doesn't have a water tank. So I have to grab a separate glass of water, stick the tube in it, and then hook the tube up to the device. It's a lot of trouble. The batter life is so-so but that wasn't a huge concern. The first time you use this device it also has an undecipherable taste, almost plasticy? That was super off-putting.  I'm used to the set up of this product now, but in the beginning it was a hassle. This product isn't the worst, but next time I'd pay a little extra for a better one.
