I have tried a couple dozen of vendors now testing MGM, 7, MIT and feel pretty well versed in this world.
I got the sample packs TMK has done the last few times and have been super impressed to say the least. 7 does what 7 does so there is of course nothing super secret or special about their 7. But what I can say is it is spot on to the claimed strength. They hit as they should and the tabs are very well mixed and pressed. They have some colored ones but surprisingly they don't stain your whole mouth like some coloreds do. If you ever had the old OO 5mg mints you know what I'm talking about. It's insane to me any manufacturer thinks that any of us want our mouth stained with product. TMK did not do this and the flavor was excellent too. I tend to like to taste the alkaloids, which for me the TMK seemed to have a good balance there.
Long story short I would recommend grabbing some of you are considering! Very well worth trying.
