A very rich looking color. Nice.
Re level tamping: same for all tamper but with this one you can adjust the depth and provided that’s ok it is pretty much self levelling of course due the flanges that stop once they hit the top of the basket. I woulnt go back to a standard tamper now that I’ve used the self levelling version for so long.
I suspect that an uneven tamp is a common cause of channeling and many wont be aware of it.
I had a tiny spirit level to test the evenness of my tamps by sitting it on top of the puck post-tamp (yes, strange and concerned looks from my wife) but that became redundant with my first self levelling tamper. Yay.
