no offence taken, and it does work, i cant help it if a few people have issues, thousands sold, 6 people with issues, but you shouldnt have to but as i mentioned until i experience the same issues all i can do is take notes and see what can be done, i think your wrong on your assumption, i worked on these for 6 months, and have sold thousand borock and only the few people you see here have issues, i have field tested these things with the most unexperienced of users and no issues.
The few things i considered issues where not a factor for testing, such as a better connector so the pin works perfectly on all models no matter what battery anyone has and adjusting the airhole so again perfect on all batteries, but that isnt performance related so i didnt factor that in since everything else just works as is and thats all i need to have them improve, some have asked for the wick to be more exposed and that easy enough to get done.
we hit the home run as the sapphire is the best out there and my offer still stands, show me a better product and ill buy you 1000 bucks worth. I do find it funny how when a product doesnt work for you few it all of a sudden is a failure but its ok, we discussed this yesterday, some things arent for certain people, and i mean no offence in anyway, but there isnt a product out their that performs better ,easier to fill, no crack, no leaks then the sapphire, no 150 tank and no 3 dollar clearo. thats a fact or at least the opinion of thousands of people so far.
Have you tried the T2 borrock, it might be more up your ally.
