Gurin Professional Rechargeable Oral Irrigator Water Flosser with High Capacity Water Tank

This is definitely stronger than What I expected. The water comes out at a powerful rate. There's an option for "low" powerful. I prefer the pulse mode it less powerful. This water mouth irrigator is very powerful. I would recommend to charge the product first. It comes with rechargeable batteries, power cord with Universal Voltage(100 to 240V~50/60Hz). I did received this product for free or at a heavily discounted price in exchange for my honest and unbiased review.
