I have been vaporizing for about 6 years now. my first vaporizer was a vapir classic i think the name was. had a few of those which worked out okay, but broke pretty easily. i got a vapir 5.0 over 3 years ago and it has worked great since. i have had a few problems. the first one being that the cord broke some how. the cord didn't break in half, but the connnection wasn't working right. so i had to hold the cord with one hand making sure it made the right connection to the unit so it would work. i sent for a replacement cord and now it works great again. it does leak a little from the lid and from where the tray inserts. besides that, it produces a strong vapor, sometimes too strong. it is always very reliable. i haven't cleaned it in months and it works fine. i usually use to whip tube because for me it is more convienient. i use it in my car a lot, which gets a little trickey, but it is doable. i just use a car adapter for it. i do recommend this unit. it is inexpensive. it is reliable. it produces a good thick vapor. it heats up quickly, within a minute. the fan noise doesn't bother me. and it has lasted a long time with very little issues. i also have an iolite, which is much more stealthy and easier on the lungs. but it takes sometimes up to 100 clicks to get the fucking thing going. and then i have to wait for a long time (30:00 is the recommended time) to get it up to optimal vaping temperature. so i just ordered a magic flight launch box. and that should work better. but we'll see. i think that nothing works as well as what you expect it to. i'd also like to check out a silver surfer. but opted for the more stealthy and portable launch box. both of which have been highly recommended by this website. oh yeah, one more thing about the vapir 5.0. when i was in amsterdam i got to try out a vocano. and i ahve to say that it really wasn't much better than the vapir 5.0. i was glad that i didn't spend the extra 350$ on it versus the vapir 5.0. the vapir was about the same. the balloon fill time was about the same. the volcano was a little easier to use with the balloons, and the vapor was smoother. besides that there wasn't a whole lot of difference. the temperature control is the same with both units. the volcano did seem like it was more sturdy and better built. but for 500$ it should be. but the vapir is a lot more portable. and by the way, you can get a plastic stand from vapir for 10 or 20$ which holds the unit upright. i got mine free with my order.
