I Have yet to hear someone complain about the flavour delivered by the plenty. The cooling coil is extremely efficient and you can replace it with a water pipe if you want. With the chamber reducer it is comparable to the Crafty or Mighty in many aspects. Additionally S&B is located in Tuttlingen, it is worldwide one of the biggest centers for medical technology. There is a lot of knowledge around on how to produce medical safe products and with what materials. S&B gets their vaporisers approved by german security control centers (TüV). I am pretty confident S&B products are some of the safest on the vaporiser market.
