I have long marveled at the problem of leakage in these simple devices. I have been a certified industrial sewing machine technician for 9-10 years and I have also been certified to work on various machines in the cotton packaging field. I worked in that field for 17 years and worked on hundreds of machines of all shapes and sizes. Because of this I saw many ways of providing lubrication and oil to machinery. I have also worked with machines that used water for steam.
My services have been so important that I have been flown in via crop duster to cotton gins ten miles from the nearest store or service station.
I have never seen a machine that used liquids of any form that did not employ the use of an O ring at the point where the fuel or oil intake "cap", "cover", "seal" by what ever name--used there was always a rubber seal to keep the fluid--any fluid from leaking out of the intake point. I have worked on machines that used a "sump" the machine sat in a pool of oil with saturated felt at the bottom. A simple pump was used to send the oil to various "wicks" that were placed at various points in the machine. There was exposed oil on machines of this type and when properly aligned, cleaned and maintained, the oil did NOT leak from the machine at the bottom OR at the intake point because an O ring or a gasket was used to seal the point of entry and other points where oil could escape through "seepage" .
Oil or heavy liquids leak worse than water because these liquids ARE heavy and they PUSH their way through seals that are metal to metal.
The new styles of vaporizors are using internal tanks instead of seperate tanks. The fluid is very "oil-like" and act like oil and PUSH against the seal at the cap where fluid is added to the vaporizer.
I am seeing this same thing in the new NEBOX starter kit. It has a great flow and it creates a tasty vape-- it is much like an old fashioned pipe. This is what I was looking for and I like this unit except that IT LEAKS it has NO rubber or felt gasket between the heavy fluid and the cap that is quite ignorantly placed at the bottom of the unit. IT should be at the top and away from the liquids pressure to escape. This unit needs and O ring and I am going to either have one made or I am going to lose very expensive liquid.
I sometimes think this is done on purpose because they KNOW it will leak and generate more sales of the fluid used. IT does not matter to them if the user buys their brand or somone else's...sooner or later the increase sales will come back to them.
But that might not be the case. The designers of this unit may not KNOW about leakage from the fuel intake point??? I SERIOUSLY DOUBT THAT.
I WILL BE LOOKING FOR A UNIT THAT HAS A TANK THAT IS FILLED FROM THE TOP AND BY DOING THAT--AS LONG AS THE UNIT IS NOT LAYED ON ITS SIDE AND ALWAYS REMAINS RELATIVELY LEVEL-- THE FLUID WILL NOT BE ABLE TO PUSH ITS WAY OUT ONTO THE BED OR YOUR HAND OR YOUR CLOTHES AND YOU WILL NOT HAVE TO SPEND ANOTHER $20.00 IN 3 DAYS. IT MIGHT LAST FOUR.
I know the manufacturers of these units KNOW they leak. The have had people test them--take them home and use them etc. And of course these testers had the same problem: Leakage.
I hope they will fix it. I will let everyone know if after I use an thin O ring if the leakage stops on this unit and I will THEN use more fluid because I am relaxed and enjoying what I bought and not having to have the stains it leaves off of my clothes, bedding and hands.
I hate dishonest or shabby organizations that KNOW their product is faulty and still send them out by the thousands to make money. This new windfall has the potential to rival the cell phone craze in a small way-- but people get tired of them leaking and having to buy coils that burn out suddenly after two days use.
Lets watch what they do over the next few months. IF enough of us make our complaints known.. they will change their products and add simple changes that will enhance the quality of the product they present to their buyers.
