Before this, I only had two. Suddenly 2 in a row were automatic. The seller tea-for-two (that lot of Bokers, one Genco and 2 no names) had this set up with an automated system and derby-exclusive (DE blades for my friend's dad) seems to have done this as soon as he/she looked into the affairs. I was using this opportunity to point'em out as I appreciate an honest seller.
