Hello Spidergawd, I'm goingt to Eindhoven regulary and know all fifteen shops in town. As someone enjoying a vape every now and then I too look out for it at every coffeeshop I visit.
Well, bad news for you as there is only one shop in Eindhoven carrying a vaporizer.
It's the High Times at Roostenlaan 24 which is a thirty minutes walk from the central station.
Due to its location far beyond the centre it's pretty much a locals place.
It's an okay enough and medium-sized coffeeshop. Bright, quite, clean with a menu containing Amnesia Haze(11€/g), Haze(11,60€/g), White Widow, Orange Bud and so on.
Hashwise they store four kinds from Morocco and one afghan. Selling bags for 7€ and 15€. Offer 5g deals, too.
Had the Haze which was good and their best moroccan hashish(9,50€/g) which was only okay for the price though(bring your hash from The Wall or Grasshopper

).
You can play pool in the smoking room(which is separated behind glass and in my humble opinon a bit too small).
Also a football table for entertaining, too. I like it there.
To hit the point

: you can find a Verdamper there(no Volcanos etc available in Eindhoven)
Have fun if you're going to Eindhoven!
