I bought a Glossray Portable Water Flosser a few years ago and have loved it! It fits nearly in the hand, easy to take in luggage when I travel and a charge lasts a long, long time. It has never leaked like some of the more popular brands I’ve tried. I got out of the habit of using it when we uprooted ourselves and moved. It had stopped working and a fresh charge or two didn’t fix it. I contacted Glossray and they sent me a brand new one asap. Super friendly and helpful. In fact, I got online this morning to buy one for my daughter.
