I picked this up from an ebay vendor that is getting some good reviews on the shaving boards. The outside bowl measures 5 1/2" diameter by 3" deep and the inside bowl is 4 1/2" diameter by 2" deep. This is the medium scuttle. Robert offers a smaller one and a larger one. Very reasonably priced at $25.00 (at the time of this review) + SH. I can't compare it to any of the other scuttles since this is my first one. It does what it's supposed to do, keep your lather and brush warm between passes. You might need to adjust your hot/cold settings til you get it right. My water to me isnt that hot but after a few mins in the Becker scuttle the lather was getting a little thin so it retains heat well. It's light weight but sturdy. I think as time goes by you will see more and more of Robert's scuttles on the shaving boards. Add another satisfied customer to the list.
