See, I only do vapes. Did have a quick look at the inconsistencies but I think as long as you have a good branded cart (my personal favourites are heavy hitters and select-at the moment) and a decent enough battery, you're good to go.
Yes, you should look into each brand to see the vibe on the Web and then make an informed decision. A good friend did say that he's not been feeling anything bad nor is he growing any extra fingers, so he's going to stick with vaping. He does have a point.
Only bad experience I've had with a cart is I ponce dropped my vape and the cart smashed. Gutted, best part of a gram gone.
