I'm fairly new to pipe-tobacco, so take all feedback with a grain of salt.
First you should know: it's small. The metal caps on the side are only a few mm larger than a quarter; my pipe tool tamper (just a simple nail-style) doesn't fit into the bowl at all, which is around 2 mm smaller than a dime.
That said, I inaugurated it with Tsuge's Ryujin blend; it smoked all the way down to the ashes despite my probably-horrible packing. Re-lighted about 2 times, and it lasted roundabout 15-20 minutes at most.
No problems, but it's definitely for small doses. Will update once it's broke in; seems to be of pretty good quality, as is their Taster Pipe.
