Personally I’ve used the dosing capsules and they’ve worked just fine. I used them almost exclusively at the beginning and still do at times. Maybe not slightly as good as packing the glass part of the stem, but worked just fine and is helpful when out and about.Dosing capsules with the TM, in general, have not faired well for most who have tried. I honestly don’t recall trying myself and the only capsules I have are for my Fury 2, which I don’t recall again if they even fit or not. Regardless, the capsule experience for many has been lacking. A better option is to pack an extra stem if you have one (or three) and use caps for the stems. I use rubber caps all the time to cover the mouthpiece side of the stock TM stem in my regular/native setup.
