I was using the glass spacers to prevent herb from falling into the oven and causing burnt glass, but those seemed to slow the heating process. They also are easy to forget and accidentally toss out with the baked herb. The capsules eliminated these issues! They heat up and cool down quickly while maintaining airflow and a clean oven. These have been a game changer for me using the Solo 3. Highly recommend accessory.
Very convenient for going out for the day, would recommend. There was a funny taste at first but it went away after a few uses. Decent price for trying something new and they were delivered quickly
Great little Dosing Capsules big enough to get a grip of nice quality and fast delivery
Fantastic!

No. It sits in your device's chamber, and the glass stem rests on top of it.
XL refers to the size and airflow of the capsule itself. It doesn't mean it goes inside an XL stem.
Yes. They're made for the Solo and Air series, including the Solo 3 V2.0 and Air MAX.
In-Chamber capsules sit in the device's chamber and take a bigger load. Micro capsules are smaller and go inside an XL stem for small, repeatable loads.
Clean them with isopropyl alcohol and let them dry before refilling.
