I also have this scale and it works well. It has a low profile so it is easy to pull directly into the cup instead of of shot glass. It isn't waterproof, but tolerates drips and such from above well. I flush my steam wand into the drip tray, and once that caused some water to get inside the battery compartment (on the bottom).
I normally remove the scale from the tray before steaming, but have forgotten a few times. It locked up one of those times, so I ordered another one assuming I had ruined it. But I put it up on the cup warmer with the battery cover off, battery out. Once it dried out, it was fine. So I have a back up on hand in case I make that mistake again.
My machine has a shot timer, so I don't need a scale that times the shot for me, and the high end scales that I am aware of all tend to be tall, which would just cause me trouble. This one is inexpensive, sensitive to 0.1 grams, thin, auto-tares when you turn it on with the cup in place. It's a winner for me.
