Thank you to Adam for his years of outstanding customer service, I wasn't happy with the fit of the crown to the inner sleeve, no quibble exchange. This was the purchase of my second Vong Titanium (i). I thought long and hard about buying a second one as there are much cheaper ways of connecting a tip to a water piece, some of which I already owned, or could mimic. I have a Glass Charlie with a carb hole, with a cut down Fat Rubber Mouthpiece (so no rubber is in the air path) I was able to mimic what a BB6 or BB9 would do with my Little Rippa. For me, I preferred the vapour of the Vong, it's probably how the air is mixed in at the tip. I do like a Wetwinder, just the feet on it make it award with a coil heater. What really decided me though is I mostly use an induction coil heater. The shape of the Vong body is just a joy for this: I hold it between thumb and index finger, push down to activate my heater, spin the Vong through 180 degrees with ease on its way to the Little Rippa and drop the Vong in. No hole to have to find to cover, my thumb is already there, naturally. I have weird throat issues with vaping. The combination of Vong, Little Rippa and technique seems to be the only way I can vape without throat issues. How I prefer to use the airport is to have it fully open but covered with my thumb. Once the chamber of the Rippa is almost full, I release my thumb. This gives me maximum vapour density with maximum cooling air flow. I put very small amounts in, so I'm often doing a reheat every minute or so. The body of the Vong does get pretty warm with the coil heater using the Vong this way, which is partly why I needed a second one, whilst the first is cooling down. Also, I need to avoid downtime if one is being cleaned. Cleaning is as simple as soaking in iso. Most of the time, it's only the tip and condenser that will need soaking.You don't need to take any rubber rings off, though I do take the rings off around the condenser. I love that a standard cotton bud can be pushed through the condenser, to dry it after rinsing the iso out with water. If the action of the rotating body isn't smooth or isn't staying in place very well, then replace the O-ring at the mouthpiece end. It uses the same O-rings as go on the tip, yes, I know it looks like it won't fit, but it does. Sliding the new O-ring over the condenser helps hold the O-ring getting it on to the first bit of the mouthpiece. I poked the old one with a pin to break it off, rather than attempt to get it off in one piece. With an FMJ and a torch lighter, the Vong is an absolute beast. The tip will get frighteningly hot but there's less heat transfer to the body. I'm not sure if this is a good or bad thing, is the metal getting hot a sign its absorbing more heat, so better cooling than glass? I wasn't a fan of the new tip at first. This was mainly due to the cap that came with it, I've switched to a non-captive cap that's "digger outter" doesn't catch on the lowest cooling fin. This new Vong tip does heat up and cool down a bit quicker that the standard five fin titanium tip does, about a second quicker in my coil heater. There's no denying it's expensive. Bear in mind that £70 of the cost is the tip and cap. Titanium is much more expensive than steel to produce. Titanium also scratches much easier than steel, so the finish on the Vong is matt rather than polished. This will help hide the inevitable scratches the Vong will pick up, particularly the wear line around where metal meets glass in a 14mm joint. Other than that, there is nothing to break or go wrong. Other than replacing worn O-rings, it will last a lifetime. If I were just a torch lighter user, only needed 14mm and needed to save money, then I'd get a second Wetwinder and FMJ. With my coil heater and Little Rippa, this is the perfect Dynavap for me.
