Hi All,
I just bought a Cleito tank 6 days ago. It was by far my favorite tank and coil for the first 4.5 days. Incredible flavor and vapor production. Then All of a sudden yesterday, the hits were becoming dry and almost flavorless. I've been doing lots of reading on reddit, and believe I'm experiencing the same problem as many other Cleito users. The problem is an airlock that occurs inside the tank and, it becomes worse with every draw. As the e-liquid is vaped, the open space above the e-liquid becomes a vacuum and does not allow the e-liquid to wick into the coil. You can visually identify this with a simple check. Unscrew the top cap a little and watch the coil. Once the vacuum is released you will see air bubbles streaming out of the cotton on the coil. I have not been able to find a solution to this issue other than relieving the pressure by opening the top cap enough to break the airlock and LEAVING IT OPEN. This is incredibly frustrating. Some people have said that after the replace the coil, everything is fine. Others have said they still have the same problem.
I'm not looking for a refund, I'm looking for a solution. Aspire is hopefully aware of this problem and working on a solution. If a permanent fix is not presented, this will be the last Aspire product that I purchase. I have used other products from them in the past WITH AND WITHOUT flaws. They owe it to their clients to fix/replace/refund the product for anyone experiencing this problem.

i am sorry to hear that.
We do hundreds of testing every day,we don't meet this kind of problem.
The coils are the consumables, the use frequency, battery wattage, the PG:VG proportion of e-liquid,how long a puff last? all can impact the coils' life.
what's more,if a clear liquid but if it has a high sugar/sweetener content it will gunk up and carmalize on the coil really fast,which will also short the coil's life.
This is subohm tank,it soaks much e-juice than MTL tanks.the vapor production is cloud lt need takes time for the coil to soak e-juice,so after 3-4 puffs,we suggest let the tank stand for a while to let the coil soak enough e-juice ,especially for high vg and thick e-juice.
Here too ... It needs a few puffs to run it in ...
I doubt aspire is going redesign these coils to permanently solve the problem. So we're going to have to live with annoying inconveniences if we keep using the Cleito.
I'm thinking about getting a TFV8 :)
It sucks to think about the dozens of expensive coils I unnecessarily threw away after only one week but now I know that it's just a design flaw and drilling one tiny hole just below the top threads fixes it.
A simple spring style release valve on the lid right beside the drip tip would solve the whole problem.
The Cleito was such an awesome tank when I first got it. Now, I'm just wasting money.
I'm a little late to the party here but has this issue been addressed or is it being swept under the rug? This is not user error.
Why don't you try the RTA deck ?
I use the RTA, because the coils that came with it sprayed the hell out of me with juice, mouth was numb constantly. Bought the fatboy glass and RTA to resolve this issue because every coil I tried was terrible. RTA was working great, no spitting/spray, no dry hits, could chainvape and then all of a sudden I got the vacuum lock issue. Now I can barely get a puff out of it, brand new coils in there yesterday and I litterally smoked my cotton today, finally got the tank finished after 100's of "burps" and the center section of my cotton is gone, 2 tails on each coil, no cotton left inside the coils, thanks aspire for letting me smoke cotton! :@ I knew I was tasting it but kept telling myself, it just needs a "burp", ya no, now I'm wheezing and everything after SMOKING cotton all day... This vapor/vacuum lock is total bs, wtf is wrong with this thing??! Save yourself the money, the coils and the RTA and the fatboy glass is not the issue... This is a defective product imo, it does not produce vapor it produces smoke from burning cotton...
I DO NOT want a refund. I just want to purchase a pack of coils that all work and that will last atleast a week and a half or 2 weeks. I'm not always a chain vaper either so I see no problem as to why they shouldn't last me that long. Thanks and good luck with the remedy!!!
Like your company name states. "ASPIRE" TO BE GREAT!!!
thank you so much for your kind support and suggestion.
In oder to support the qualified products to aspire customers,every of our products is checked by three procedures.
The cleito tank is for high wattage,cloud vaper,so it will takes much e-juice than normal mouth to lung tanks.
Here some kind suggestion from aspire engineer while using the cleito tank to avoid burnt tast:
Our suggestion is that start at a low wattage for example the 0.4 ohm coil rated40-60W, start use it at 25W,use it for a few puffs, then slowly turn up the wattage, until you get the best flavor and vaper amount.
Then use at this wattage. The cleito is for cloud vapor,it need time for the atomizer to soak enough e-juice.We suggest to let the tank have a rest for every a few puffs, to let the tank soak jucie especially when the VG of juice is high.After refilling,we need let the tank sit for awhile, to allow the coil to soak up the liquid,What's more,please refilling the tank in time before the e-juice inside the tank completely used up to avoid burn taste.
Every refilling,customer need let the device stand up for at least 2 minutes.
At last,when long time no using(more than 2 hours or we can not use up one tank e-juice one day),the cotton inside the atomizer will soak overmuch e-juice,which will stop e-juice and air entering into the atomizer.so please don't let the tank with e-juice stand up for long time.
Any problem,please feel free to contact our service : service@aspirecig.com,they will check wth our engineer and give the suggestion and solution
