Dicodes 2380 and a squape r. The squape has a window but I've dropped these two over and over again. I even took a chunk out of concrete.
Yep, the secret is to inspect them before buying. If there's an oring on each end of the glass tube and a recess where the glass window is and the metal protrudes out a little, the glass won't hit the concrete. It's not unbreakable, but the clearance helps.
Poly tubes usually survive drops in my experience.
