I might have to try the buy-two solution. I went years without breaking one, and suddenly I'm going through them like candy. It usually happens during clean-up. The last one I was trying to be extra careful. I cleaned it and let it dry, then when I was going to put it away, I bumped it and it fell to the floor. Sigh... I do wonder if the ones I've been buying are particularly fragile.
I could just skip the hydrometer reading, but then I wouldn't be able to drink the sample.
