It worked for awhile [SEP] This worked great for awhile. For some reason, they put the trap door to refill this product toward the bottom. Unfortunately, it began leaking after awhile.  This would not be a big deal if the door to refill it was at the top, but it’s not. I now have to keep something under it to contain the liquid coming out of it. Poor design.  My daughter needs a water flosser.  I will look for a different one for her.
