Review (3/5): Inefficient battery, diminishing pressure and tips don't stay in place
[[VIDEOID:c9da7b4a8dedfe802811467a6d8807d1]] The device is fantastic. The DIY and low modes are good for beginners but the high one provides the better and powerful cleaning that I need for my braces (you can see inthe video that it is so strong to remove mold from a wall). I tried to remove the water tank like instructions said but didn't work, then I tried in opposite way: putting the flosser upside down, holding it with my right hand and turning the tank anticlock wise with my left hand, it came off easily. The only bad experience I got with this flosser was that I charged it for 4 whole hours but the charge just lasted for 2 weeks, using it twice a day in low mode. Then I recharge again and like I used it only in high mode it only lasted 5 days. I got in contact with the customer service and they sent me a new flosser, which you can see in the sealed box. Let's see how the second one behaves.
Edit: after 6 months of usage, I can say this flosser is very powerful and stay up, but battery and power don't last more than one week. Also the tips don't stay in place so I had to press it to made to work, so it isn't so friendly and easy to use anymore. I would say the flosser does its work BUT with many flaws, so buy at your own risk. I will give 3 stars because the support was good enough to replace the first flosser and because they ended giving me back my $30 I originally paid because of the many flaws the product has.
