Well Ive had my Haze for a couple of months now and unlike any other vape Ive owned, I have zero desire to go back to combustion. This is the vape Ive been looking for. While its not the most stealthy of portables, Ill gladly trade that for the ease of use factor, the cool vapor, the improved taste and removable batteries. I can put 2 filled screens in the vape, prepack my 4 cans, have all my batteries charged up and be good to go for the whole weekend. I pack it all up in my RYOT bag and its a fully portable party. I plan to add a few more cans and a water tool (on the way) to complete my party kit. I havent had an issue that has required customer service so I cant speak to that but the upgrade program is in a word, awesome. Haze really did a great job with the 2.5 and except for a few minor nit picks like the oven door being a bit hard to open ( proper opening technique helps with that a lot but people with arthritis will likely have issues ) and the sticky mouthpiece, they really hit the sweet spot for what I want out of a portable vape. I cant wait to see what they come up with in version 3.0. Lastly, if you can not get great vapor clouds from the Haze you either have a bad unit or you are just not doing it right, because the Haze absolutely rocks! Ill just add, if you hit the Haze as soon as your oven lights stop blinking, you will probably not get a solid toke. Give it about 15 seconds once the chamber is fully heated and youre good to go.
