The mouthpiece. Bless its little heart. Seems like the only options are carry the mouthpiece separate, and stick it in as needed, or have fingertips/nails of steel to pry it out of its self-storage, once it's been used once. See, I like the ability to use, use later, use later again...
Yes, I know I can use the tweezers. But I don't want to carry them. I want to not need a separate tool along every time...
The SS MP, being slightly more porous than the boro, gets a bit sticky and hard to slide out quicker. Cleaning is easy, of course, though I do seem to do a lot of swabbing inside the MP channel [insert scene from Sense and Sensibility: "What is swabbing"] to get all the residue.
Everyone at Haze Technologies is young, agile, dexterous, and have perfect vision, I'm guessing. Everything is really tiny, and needs really good fine motor skills, like the herb cans with the SS screen lids.
Don't get me wrong, I love my Haze. But it is not for anyone with fine motor issues, arthritic fingers, or difficulty working with really small parts.
What it does, it does really, really well.
