I think it was nerak who posted it originally so he gets all the credit for the idea. Anyway, I was at the hardware store getting something for a faucet, and of course had my Reo in my pocket. The one thing that I didn't like about the Reomizer 2.0 was the gap at the bottom where it was milled to fit into the drip cup. Long story short add a #7 o-ring (1/2" O.D. x 3/8" I.D. x 1/16") and the gap is gone! It's a minor thing but now my Reo is just a little bit better. I've been using it this way for several days and haven't had any issues so far.
