Iβve used this bowl about 10 times, impressed with the draw when using any kind of pipe, handles heat amazingly well, even with darker tobaccos, has amazing consistency with heat distribution and plenty of space for about 25g+ of tobacco with an HMD. Thoroughly impressed, anyone who wants a good bowl for single smoking or with a group with an HMD on it, look no further! Fits my Kaloud perfectly and my Oduman Ignis works great as well, no issues!
