I love metal or glass mouthpieces. I find titanium has a taste. I was happy to find stainless steel Vapman mouthpieces since they are tasteless and don't interfere with the taste of the herb. These feel better on the lios the plastic mouthpieces and makes the Vapmans even a touch classier. Hard to believe perfection could be improved upon but Vapman did just that.
