i bought the topoo vaporizer vp-100 and tested it out today on a nick of schwag that my friend gave me for free. it took a blunt and a shitload of bong hits to actually feel the high off these low quality regs when i first sampled it. but with my vape...OMG....i was fucking high. i did not think a vaporizer would be this fucking great.im actually mad at myself for not buying one sooner.i could have saved my lungs alot of stress while getting high as FUCK!!!
