Broken item

I purchased a pore your heart out facial cleansing brush and had the one for a couple of months the first one broke from water damage but the seal was always on tight and the only part of it that ever got wet was the brush head. After that one broke I purchased another one, after two weeks I accidentally dropped it on the floor and it was still working and while I was cleansing my face it just stopped working. Mind you a drop like that shouldn't have made the machine stop working.
