I recently joined FC and have been using my vaporizer for about 12-18 months so was a bit surprised when I could not find a review of it on here. A little bit of searching around found that it was mentioned, in hushed tones it seemed, because it was a poor product and that there were other better products available. Well i have only used this vape so I cannot say that is right or wrong but i will give you my honest opinion of the Vapir Air One 5.0. I bought it from the Vapir website after emailing them to see if they did a model that would work in the UK, I did not want to spend my money on something electrical which would not work, or worse, break when i plugged it in. They responded pretty quickly so i placed my order. Due to a decent exchange rate at the time I purchased 2 for 150, one for me and one as a gift for my younger brother. They arrived in approx 10 days time in a simple brown box, i didnt have to pay any tax on it either but your experience may differ here. (i have ordered things from abroad before and sometimes i have to pay to collect and other times I dont!?) I only use the vape with the bags. I set the temp anywhere between 170 and 190, depending on the bud I am using and how fresh it is. Now, I havent done any scientific studies to ensure that the digital gauge is reporting the temperature that it actually gets to and if that temp is measured at the point where the herb cartridge sits, but, it is certainly hot enough to work and there is a decent amount of variation available for the temperature to find one that suits you and your bud. Now, to use the vaporizer you have to grind up your bud and put it into the "herb disks" (i like to call them cartridges, as in shotgun or N64, take your pick). I like these, although I found them fiddly at first. I can pack three of these and they will do me all night. These sit in a little tray to get them in and out of place in the vape. To turn on the vaporizer you plug it in to the mains and underneath the handle is a power switch, once you flip this switch the LCD displays the temperature 250 F and the fan starts. Thre is a switch to control fan speed on the inside of the handle, you have high, medium and low, which also corresponds to the pitch of the whine that the fan makes. Switch this to low while you set up the vaporizer. To set the temperature i first have to press a button to switch from fahrenheit (the default option) to celsius (what i work in) once that is done you press the + or - button to get to your desired temp. Once you are happy you press the Flame/Fire button to start the heat, when you do this an anry red light will appear above the LCD until it reaches the desired temperature, at which stage it turns a jolly green. Once the green light is on you now have to act like a Formula 1 pit team (its not that bad really), first i pop in the cartridge which sits in an ejectable tray, then you have to put the hose into the end of the vaporiser. The latter part of which can be a pain. The top of the vaporiser twists off, to reveal a rubber section which sits inside the top of the vape. This, combined with the rubber O ring on the bit that comes off, is in an effort to create an airtight chamber so that the vapour is directed into the now attached tube and bag. And I must say it is very succesful. I do not notice any vapour leak from either the pipe or the vaporizer or the bag. I know this has been a problem mentioned in other reviews, but i only notice the vapor leaking out when i leave the bag overfill, (usually because i am playing xbox). EDIT: Oh and remember to turn the fan back up to High once the bag is attached. From 1 cartridge i usually fill 5 bags, although recently I was thinking of purchasing some of the volcano bags and modifying them so i could just fill one and be done with it. As a result of this method, i usually just fill 2 bags whilst hitting them, switching them when the one i am using is empty or if the one on the vape is almost full, the last two bags i leave fill to the max and, as i leave the pipes in the bags, i can fold them over to create an airtight seal to keep the vapour in the bag so i can toke on it a while. You cannot turn the Vapir One 5.0 off immediately after use, first of all you have to turn the heat off, pressing the flame/fire button will switch the jolly green light off but the fan will still be going. The manufacturer recommends letting it cool down for 5 minutes before switching the whole thing off. In reality I usully leave it 1-2 minutes before i switch it off. You can check the temperature by quickly flicking the flame button, this will turn it on again (if you leave it for more than a second the temp really shoots up) and let you see what the current temp is, i usually let it get down to approx 40 celsius so after chcking a few times i determined that it took about 90 seconds to cool down from 175 celsius so i tend to adjusst to 2 mins when i use it at 190 celsius. Now the vapour. The vapor that you first get off it is nice tasting thick vapour, this will be for the first 3 bags, the last 2 tend to have a thinner vapour but are very definitely active. some of my friends think they are the "worst" ones to have. I use my Vapir One lying on the side, that is, i set it on the sofa with the display facing up, i have heard people say you should have it upright but i can never be bothered holding it so i lie it on its side and it has worked for me for as long as i have had it. I read somewhere earlier someone saying he used it upside down to stop oil dripping down onto the heating element, i have never experienced that, perhaps because i use it sideways, but there is no build up of sticky residue inside the vaporizer. There is some residue above the cartridge, i.e, where it is being forced out into the tube (which will also acquire this brown tinge if you use the same end of the tube all the time) but this does not appear to have affected the performance at all. As far as cleaning goes I have never done any, neither the cartridges, the vaporiser or the bags and tubes have had anything done to them since i bought it. i think i should perhaps change the tubes and maybe clean the bags and cartridges but it really doesnt seem to be affecting performance so i dont really bother. So thats it, my review. let me know what you think. Oh and I am curently considering getting a new vape, all the money i have saved from cigs and papers is probably going toward an extreme after someone else recommended it to me. i think the wife will prefer it too as it looks much nicer than the vapir one. TL;DR - a good vaporiser, not problematic like its predecessor models, easy to learn to use, good temperature variation, bag or whip delivery, minimal maintenance, con- noisy fan which can get annoying.
