Review on 🦷 Renpho Cordless Water Teeth Cleaner - Portable Oral Irrigator for Teeth, Gums, Braces, Dental Care with Travel Bag - 4 Modes, 5 Flossing Tips - Rechargeable, Anti-Leak, IPX7 Waterproof (White) by Aaron Campbell

Here are my observations after four uses: Pros: The power of the floss, especially in normal mode, is high enough to cause bleeding gums. I checked the cleanliness of my teeth with dental floss and there wasn't a drop of dirt on it. Cons: This model could have been designed better. The power button and four mode buttons (Normal, Soft, Pulse, and DIY Mode) should be on the back of the handle - you can play it like a voice recorder while looking in the mirror; This way you could easily get to the back of the teeth. The ends of the floss should be bent closer to a 90 degree angle so you don't have to bend too far to let the water flow; Water flow is an issue because the hose in the 300ml water tank that draws in water doesn't point straight down, but curves backwards and away from where the water is when the floss is at an angle of 90 degrees (at least the hose can be). tilted in the opposite direction, which could keep it submerged longer). It is difficult to fill and drain all the water in and out of the tank. The grip is uncomfortable to hold as it tapers rather than a pen. The pen felt too big even in my large hand. Overall, this RENPHO water silk is effective for cleaning teeth, but somewhat impractical to use.
