All research seems to indicate Titanium as the healthiest option. These capsules are super solid, very durable, easy to handle and have good airflow. Worth the $$ and they’ll outlive me.

These titanium capsules are built to last a lifetime. They’re easy to refill, but you need to fill them properly for the lid to close without issues. Initially, I thought they might fall out, but they are much easier to clean than steel. The caddy is incredibly convenient.

Personally, I’d prefer if the capsule size were twice as high and the holes were less fine, as they tend to clog easily. They don’t burn poorly with the right grind. Having titanium accessories for the TM2 really makes a difference in cooling and flavor. Only for connoisseurs. Cheers!

It works very well with the TM2. I also love the smell proof tube it comes with.

These caps are a must for max cleanliness and portability for your on the go needs. Highly recommended.
