I bought on just recently...here's my thoughts on it, reposted from another forum...
Ok, I had my inaugural smoke and have to say my initial impression is pretty good. But then, it's my first "good" pipe and chances are unless it was a total turd I'd like it, right?
What impresses me the most is the comfort of the pipe and the stem in particular. From reading reviews it seemed the overall knock on the Mario Grandi pipes were their stems, but that's certainly not the case in the one I got. For starters, the tenon fits the mortise just right...it comes on and off with ease, yet forms a good seal. I can put my palm over the chamber and when drawing on the pipe, there is no leakage anywhere. It is also very comfortable and fits very well in my teeth. For whatever reason, it's size and shape are just about perfect for me and it's very pleasing.
The pipe itself fits well in my hand and smokes very well. Being new, I still have a tendency to smoke a little hot, but this baby never become more than lukewarm at best and a 1/2 a bowl of PA lasted me a good 90 minutes before it was time to empty it out. Very enjoyable to the point that I don't even want to smoke any of my other pipes at this point.
So overall, I would definitely recommend that anyone considering a Mario Grandi go ahead an pull the trigger on one. It's a great pipe for the price. I still have my eye on that Peterson (or one like it) that I posted about a few replies back, but I fully intend on owning another Grandi at some time in the future.
