I'm tempted to get a HV vape pen but it's a little pricey considering i'll probably never buy another cartridge once this lockdown is over. Man, I wish couriers were still up and running. They could probably go about their business while maintaining good social distancing practices.
I hear that its pricey, but the effect of the stuff is legit hey...
Lemme temper that by saying, after day one i can confirm that 2 or 3 hard puffs will make u feel like u smoked a joint, but u didnt, but u deeeed... u deed smoke a joint

cos you will cough, and you will feel the effect immediately, and each cough will make u higher... just like a joint... but u didnt smoke a joint fool!
For me, the effect lasted about 2 hours... that was the 0.5g THC D9 cart. I got the Blue dream strain. I speak under correction but the 1g vs 0.5g referrers to the strength and not the quantity, cos my 0.5g cartridge is pretty much full.
That was R1150
The device alone is R400 and its reusable, so thats cool in my book.
According to the video with the dagggacouple they say the cart is good for +/- 200 pulls
R750 for +/- 200 pulls of what is essentially indoor in a strain of your choice. And its for reals.
lets say 4 pulls to get high means u can get high 50 times for 2 hours at a time for R750?
OR in my case, 25 times for 2 ppl.
So while the initial cost seems pricey... the numbers seem to be in your favour
Lets say a gram of indoor at 150 - 180 (i dunno, i havent bought actual weed in many many years) gets u 2 to 3 joints? that means that 750 will get u high 15 times.. ?
I will ofcourse give more feedback as the cart goes on. but for now i think the math is
slightly in my favour or at worst, equal ?
