UsmileUltrasonic Water Flosser Cordless, Portable Water Flosser for Teeth with 4 Modes 3 Jet Tips, Rechargeable Oral Irrigator with IPX7 Waterproof Telescopic Water Tank for Travel Home, CY1 Green

I gave it only 3 stars because of the charger, the other things I could live with. I loved it regardless of the constant cleaning, but unfortunately I had to return it due to the charger not working. After charging it for the 1st time it still showed as red and after another 2 weeks needed charging again, but after charging for the maximum amount of time it never worked again! But it does have a 1 year warranty and it has many things that I like about it so I may try another one.ProsFlosser options are brilliant and on the highest setting it does a great job at flossingFolds up small and is easy to pack for travelIt's easy to cleanIt looks goodDoesn't get any limescale like some of the others I have usedConsIt needs cleaning a lot as bits of food get stuck in-between where you hold the flosser and where the water goes but that doesn't take long.At the top of the inside there is a silicone part that turned black but doesn't affect anything.The part where the water goes and where you hold the flosser rides up during flossing regardless of there being something that is meant to hold it in place.The charger was faulty but I may have been unlucky
