Bests & Worsts Reviews from Amazon

We've known for some time that these glasses are fragile and have gone through several but we have continued to use them because we like the thermal quality. Recently however we were serving cocktails and the dropping of ice cubes into the glass broke the inner layer. We didn't realise this until our guest was nearly finished. My wife saw the crack through the outer glass and sure enough there was a piece of glass floating along with the ice cubes. Our guest could easily have swallowed it. We do like these glasses for their design and functionality but this company needs to own up to the fragility and the dangers of their product.
