So I combusted for what feels like the first time in a year or so last night.
I was starting up the second session of the day with the UFO (it actually got here Thursday!) and had a half-done trench all ready to go. Plugged in the PA and got started on a typical hit in a way that normally doesn't even get close to combustion. What I failed to remember is that earlier in the day, after my first session with the UFO, I had been messing around with my PA and a multimeter thanks to all the talk about batteries.
Instead of the usual 45-50% I have the PA set to, I left it maxed out at 100%.
So, very soon after I started the first hit, the trench went up in smoke!
I managed to get all the material off the screen and starve it of oxygen before any real damage was done, and after a quick burn-off and brushing the trench is none the worse for wear. Gonna have a stinky box for a while though.
Anyways, first impressions on the UFO from my limited time with it:
Certainly a nice piece of kit! Fits in perfectly with other MF products and looks excellent. All the acrylic stems - downstems included - are to the same specs as a regular draw stem (1/4 inch). I had a better time using two draw whips, a la the Orbiter, since with the regular long draw stem it's tough to get a good look at the vapor production inside the glass. Bubbles pretty well and is quiet too. Depending on the size of the glass you use it can be a real hard hitter!
A couple of nitpicks, though: the suggested clearing method from the little instructional card you get is to slightly lift up the entire UFO from the rim of the glass you're using. I found this method to let more vapor escape than I could draw in. I'm thinking a carb hole on the opposite side of the draw stem hole would work well for this purpose, and I'm going to try drilling one myself eventually. That could also possibly allow for a "sharing the milkshake" scenario with another draw stem or whip on the opposite side!
The seal itself isn't totally perfect, either, but that's doesn't seem to be that big of a deal.
I'm definitely going to try it out with other glasses and vessels, though!
I'm thinking an empty glass honey jar could work pretty well...
