Better Than a Regular Slate
I got one of these as a present for Christmas from my Wife. I thought it was a bit on the hoaky side as I couldn't picture myself using an under water etch a sketch. So, I tried it out and guess what? I can't live without it. I like the ease of use and the fact that I dont have to rub sand to clean it. Now I can rather easily and clearly communicate underwater!!! I wish the unit was a it less thick but that goes with the territory.
