Blomus Duo Polished Wall-Mounted Toothbrush Glass

I recently purchased this wall mount toothbrush holder but the glass is very thin and feels more like plastic. My tumbler cracked at the bottom from normal use(a couple of toothbrushes and toothpaste). I contacted Blomus customer service and they sent me a replacement right away. Shortly after, the tumbler cracked once again at the bottom. Next time, I'll spend a little more money or make sure the glass is thicker and not so fragile. This tumbler looks nice and modern but won't hold up to normal use.
