I have never tried the Minivap, but I take it on good authority that it is absolutely top-of-the-line for flavour as far as desktops go. And all round a very decent vaporizer I hear many times, with very little criticism as well I have heard of it very time to be fair.
But I also can very strongly recommend the Herborizer Ti for exceptional flavour and vapor quality of the highest order. Hands down better flavour and the Evo, slightly better flavour than the Flowerpot.
It also hits as hard as any desktop out there, is dead easy and fun to use. Fast powerful extraction which can be as fast or prolonged as you wish.
You can kill a full size load (macro amounts) in 1 or 2 monster but still shockingly smooth draws, or stretch it out with multiple equally smooth and tasty hits.
What I noticed when testing the digital version of this vaporizer out recently is how much more than other models the flavour does not seem to decline as the load gets exhausted.
The taste is preserved and more consistent throughout the whole load until there is no more vapor without really never noticing that burnt popcorn taste.
The glass "Elev8r" by 7th Floor is the best tasting vaporizer I have ever used. But I was actually very surprised to find that the Herborizer Ti runs the Elev8r very close for its money.
With the Elev8r the taste does worsen towards the end of the load, and it keeps producing vapor past the point of pleasantness.
But this doesn't seem to happen with the herborizer. So I can strongly recommend it for being one of the purest tasting desktop vaporizers you will find but in most categories it is genuinely hard to beat especially the effects which are as Potent as just about any other model and more so slightly and the Flowerpot for example weight for weight of herb.
The Flowerpot does deliver excellent flavour at low temps though and is itself a brilliant vape IME and IMO.
