Problems:
- Vaping quality, Vapir No2 general functionality, is related directly to cleansing. To keep it working right, make good cluds, and not have a burning residue glued to the internal walls, and parts, a religious cleaning is needed. For daily vaping as I was doing, 10 sessions a day at least, at least after 3 days of using, and best if every day. Obstructed screen make pulling harder and won´t make good clouds.
- You have to clean the 2 metal screens, wich is a bit tedious in my oppinion. For good clouds and taste you become dependant of cleansing of the screens, and the whole internal chamber/parts. So brushing is necessary to remove residues in upper and lower screen after each individual session/use. Only blowing won´t remove some sticky herb. So be prepared to keep cleaning it religiously with the brush to remove sticked abv on the screens, and brass chamber.
- Besides the 2 metal screens, the internal chamber, the top cap, and the detachable plastic rings the holds uppers screen. So if you buy it keep in mind that you´ll spend lot of time cleaning it. See the Picture what parts I´m talking about:
- As mentioned before on this thread, there´s empty space behind the buttons, that could make battery go up, so No2could be smaller and more stealth and easily pocket fitable .
- battery only lasts 1 hour, sometimes a little bit more. I had several experiences that I took the No2 to friends house, and battery ran out, so I whenever I had to vape on other ppl´s house, I had to take the Ac/Dc power adaptor with me ! That is not so ´portable´.
- Ac/Dc cable has 74cm length, I wish it where 2meters (considering 1 hr battery...) -> Many times I took No2 to friends house battery ran out and I plugged Ac adapter to the wall, and in some cases it was awkward because people needed to be very close to the wall plug. At home I could use a chord extension, but not on other peoples house. So cable length would help to compensate that problem, wich makes the use o Ac/Dc Adapter an obligation to mantain battery, or vape session when battery runs out.
- Ac/dc cable connection to VApir No2 sometimes easily disconnects, specially if you´re with friends doing a vaping session, and battery is not full, or ended, so I have to plug it in on power adaptor. Again the 1 hour battery is related to the Ac/dc power adaptor.
- sometimes the upper screens get loose, consequences:
- aspirate somes herb, little particles get inside the mouth
- you are obligated to fix it with your hands making your finger smell like herb, as if you just smoked a joint. So beware if you take the No2 work, or have a professional meeting, and accidentaly metal screens get loose and you have to reposition it with you fingers. Wash your hands after touching inside parts, oil is very very smelly.
- smell / taste of plastic on first times
- if you´re not rigorous with cleaning, everyday or at least once week, oil (ear wax) could stick in the little holes of the metal screen mesh, making it very very hard to remove if you´re lazy on cleansing. You must scrap with nail or a metal wich can eventualy make holes in the net, needing to buy new ones. If you not clean it often, screen gets obstructed and as I theorize heat build on because there´s no airflow ending up in burned herb (and maybe burned internal components? as my inner rubber ring).
- Excess of edgy corners in the internal chambers, so it´s easier to sticky residue and small particles of grinder herb to deposit on those sides making difficult to screw and unscrew (open and close cap), also harder to clean. I resolve this by heating the device so the sticky oil melts, making it easier to open the top cover or internal part for cleaning. Use a pointed device to remove particles in those parts. In future project make less edges and/or more rounded.See picture above wich I signeled some of those corners.
- Since it´s 1h of battery (some say even 1h30m), if you plan to go outdoors, I noticed I beggan to be really picky/paranoical on outdoor usage. Practical personal experience: every sunday I go to a park and stay 4 hs or more there, reading, playing guitar, so I have to remind me how long I´ve vaped, so I can enjoy more sessions while I´m there. It´s a bit annoying and frustranting having to rethink that (when to use once outdoors + how much time/battery left for more vaping sessions).
-
Vapir does not indicates how to properly clean the device, and with wich type of material or even wich cleaning product we can use. TOTAL FAIL.
Could lead to people using corrosive products damaging the device and eventually could cause harm to peoples health.
- Manual ilustrations are tiny and not clear, making it difficult to understand how to unscrew all parts. Vapir should make a official video on how to clean the device.
- Also as some reported, the lower metal screen sometimes is hard to remove, you got to give it a few tries.
- On of my bamboo stick broke very easily, since the tip of it is very fine. In an effort to remove the lower screen it broke. Nedless to say you can use any other improvised tool to remove the lower screen, so avoid buying new ones. Vapir should make a unique piece using of a stronger material so you don´t have the disapointing experience of breaking those bamboo sticks or buying new ones.
- If you buy bellow the $179,99, you don´t get warranty. Why the hell they sell below $ 179 ?
- No indication on the manual that the brush that comes with No2 melts if you try to clean the device while it´s hot. So plastic sticks on the chamber !!!! That is very dangerous. So why the hell Vapir gave us a potentially dangerous material to clean their device and don´t warn us ? You can smoke fumes from melted bristle !! Mine melted see pic, as some users also reported.
- Worst problem of No2: My No2 rubber ring melted. I noticed that ocasionally, I did not see it happening. So I probably smoked those fumes ! ZOOM it for better view.
- Crazy temperature readings in some rare occasions. In brazilian forum growroom.net, a No2 owner posted a video of a problem that some other people also reported in this and other boards
(could this be the problem with burning herb, or making the rubber melt?):
THEORY WHY IT MELTED :
Possible problems that could lead to the melting of the No2 parts, or even burnt smell or plastic smell and burnt herb:
- Could be: Screens are obstructed (clog) by herb resin or small particle so when there´s no air flow, temperature raises as in a oven, and goes beyond 204ºC (400ºF), eventually melting the rubber, and burns herb.
- Could be that the finner the herb it´s grinded the easier it´s it to clog air flow on both screens.
- Or could be: Thermostat goes crazy, no matter if the screen is non obstructed, temperature rises too much, and melts rubbers, and burns herb.
- Or themostat goes crazy because screen is obstructed, heat builds up, and since it cannot display temperatures above 400ºF it simple goes crazy, up and down, as in the video.
Symptoms:
The few times the herb was burned, it became black, taste was awfull and on the upper screen there was a lot of fine grinded herb that seens to have created a wall avoiding heat passage, ABC was also black.
When that happened, temperature sensor went wild, from 165ºC to 198ºC and so on up and down in seconds. See above videos as factual example.
In resume, either is the lack of cleansing that leads to screens clog, so temperature build up, as heat pressure cannot get out. Either some official and non-official Vapir No2 models have faulty heater/thermostate that aleatory sometimes heats up way beyond 400ºF, again making it a dangerous product for health, since rubber melting occurs.
In any case I do conclude despite some users being happy with it, it has some project problems concerning cleansing, size, stealthiness, battery duration/stability/indicator. And in the worst scenario, as happened to me, a fact that it has a rubber inside the chamber ! And mine melted !
As I stated in the beggining of my review I do not recommend this device since people around the world report melting of the rubber ring on official and "non official" Vapir no2´s. Everything that I complained on this review becomes really really small next to these melting issue. As in the very start of this topic, some people pointed out, I don´t think I´ll trust Vapir from now one, lot´s of things that could be fixed/optimized.
Sorry for the long post.
