The smoke is terrible, the vapour is wonderful.
You don't necessarily need a GVG to vape properly.
The machine works great and can be made in a few minutes for almost free.
Keep the flame a few inches away and find the sweet spot.
As mentioned already, changa is basically fool proof as well.
Do a search for "the machine" or "the key" for some easy to vape pipe instructions.
If your pipe is set up to use vertically, you can use a bic, otherwise a torch lighter at a distance is needed.
The vapour should be smooth and so delicious, you will hardly know it's there, though.
It is way less effective when burnt though, so start low and get your technique dialed in first before upping the dose.
