From delighted to disappointed, a story in three acts by Nosedog.
My first brush was a crappy supermarket brush that fell to pieces in weeks. During that time I ordered a Frank's Shaving brush (best badger, I think) and was delighted with it. The original brush went into the bin. Then I bought a Semogue boar and rotated between the FS and the Smoggy for quite a while.
Then I bought a Simpsons, and have since had no desire whatsoever to use the FS brush ever again. That was probably nine months ago. The one time I did use it (travel?), I was just as disappointed as I expected to be. The Smoggy gets very occasional use (travel, and when I want the boar stiffness for some reason).
Seriously, if you want to really enjoy using a shaving brush every day or so, you owe it to yourself to buy something better than a Frank's Shaving brush. If not immediately, then eventually.
