I have a Dirty Bird 1.5 in Berry Rim on Blue with regular lather ridges. It keeps my lather very warm throughout my longest shaves (upwards of 35 minutes). Julie was a pleasure to work with when I ordered and she finished the item on schedule. The scuttle was delivered very well wrapped with little chance of being broken in the mail unless it were delivered by Ace Ventura. The regular ridges really help provide enough friction to help produce a great lather without trapping the lather in them at all. I've used a 2.0 with web ridges and it's a monster suitable for two people; the web ridges tended to trap lather in them as well. There's a lip on the inside of the top so the lather doesn't creep out as easily.

I'm very happy and feel that the product I received was well worth the money I spent on it. I hope this helps.
