Query: Nice, but fragile

I purchased four of these. I had carried one for a couple of years until I left liquid in it that froze and broke the mug. It is easy to insert pictures and they remain dry fairly well as long as you check the tightness of the seal occasionally. However, when I recieved the mugs 3 of 4 were broken. They appear more fargile than the one I had before. Though I have not found a better photo mug yet.
