I remember a while back someone saying they would sell their Supreme once they got their Cloud. To me, the VXC heat retention, narrow vapor path, narrow, bowl, and hits compare best to the S, and i would never get rid of mine. I could use it on the run, or during a power-outage. Anyway, enough about the Supreme but i feel the VXC compares better to the S then then the LSV, MW, or VHW. Here it goes anyway.
Random Thoughts:
Just the concept of being able to look right down the all glass vapor path and see through to the other side is amazing. I have not wanted to use any other vaporizer since i got this one, this has included my PD. I know i will work back in my PD and MFLB again, but haven't thus far. Think my LB will get back in the rotation tomorrow for some away from home work. But the VXC heats in 3 minutes, loads quick and easy, and is fun as hell to use, gets you ripped, and browns through everything. The Eclipse has its own use too, but it is to smoke oil, bubble hash, pressed kief, ect. Not truly vape. More on that later.
Efficiency:
Interesting place to start. How would one define efficient? If finding a perfect temp for you then getting your entire load the same color is your definition of efficient, then the VXC wins. I think this is extremely efficient. You will get more hits with the LSV and MW for sure, but will have a much more difficult time browning all your herb to the exact same color, especially without temp adjustment like i am able to do with the VXC. Same temp begining to end, with no compromise in thickness of vapor. Low temp, and thick... Amazing. The VXC simply extracts the goodies better then the others.
You will get a few hits that taste less then perfect at the end, but much less effort and asshole hits then you would get with any other vape and you can brown everything you favorite color all the way through, same temp start to finish, AMAZING. Did i say that already? I also found, one stir even for a full bowl pack, no problem.
Taste:
Very very very good. Compares favorably to the MW and the VHW, and LSV. Not going to lie, they all provide really clean vapor taste. I think the VXC excels in that it has a water tool that is small enough to preserve taste, and with low volume water capacity. It just simple works very well and tastes great right out the box. No need to try tons of glass till you find a winner, unless you want to that is.
one more important point on taste, because vapor is so thick at low temp, i feel i get a deep more rich flavor from the VXC. There is certain flavors at the back of my pallet or something, that just leave me smacking my lips
Favorites so far; Bluererry Gum, LSD, Blue Mystic, Sour Diesel, and of course some pure bubble hash! Yummy!
Ease of use:
I would have to say we have a new winner here. The MW is pretty easy to use too, but i see a couple of big differences. I much prefer the EZ load bowl of the VXC with no movable parts that can (and did) break. i broke a MW bowl on my second or third night using it. I have gone years with the VHW without breaking a single of my three bowls. No sticky or hot pieces to wait for cooling either, oh yeah! A quicker heat up time then any competitor, and a solid system that tells you when you are to the heat you desire and have set the temp to. Not just that you may or may not be in a desirable vapor zone (like the MW green light), or guess and check like the VHW/LSV.
Also, the dial is on the unit, where it should be, and the VXC is pulled from any water tool (including the hydratree) easier then the MW, LSV, or VHW, plus its all one motion and quicker to do. With the others, you need to remove your wand, place it somewhere safe, then remove the bowl to clear the glass of vapor. Removing the VXC unit/lifting the tree is easy and only a single step process.
I have no concern about burning the cord ever, like i do sometimes with the MW. The VXC needs the least stirring of any of the others, and you can have a bowl waiting on the side. Better yet, 3 or 4 waiting of various strains. Last and not least, when the VXC hits the green light, it is optimal and ready to go. Unlike all the other wand vapes, you have to wait much longer for what i personally consider optimal vape temp, or the glass pieces to get hot throughout.
Oh yeah, best temp dial of the bunch, although i like how the LSV dial looks it is too "easy" to adjust.
Only negative is that it does get hot quick, and you need to remember to turn it off if not hitting it for a couple minutes or longer. I think some improvement may be made in insulation for long term use in the production units, but i am uncertain,
Durability:
I haven't dropped it so far but seems it would beat all but the LSV when in full suit and armor. Cant say for certain without a level in testing i am unwilling to go to. I can say, one of the pitfalls is the HydraTrees can roll or topple easily. I believe a solution in the forum of a stand is being worked on by SM
Thickness of Vapor:
As said before, this is the new king. The heat retention beats out even the VHW, and compares best to the Supreme. The VXC is just much more consistent with much better taste. I have tried it with water tools big and small, including adding my Luke Wilson inline attachment onto a couple of my water tools and ripping through the whole thing as hard as i could. Very VERY nice. Having a straight visible vapor path with no restriction is also awesome.
Appearance:
This beast looks cool as hell. Once again, a glass vapor path you can actually look straight through? amazing. Brush SS finish for production model (i think). Thick durable cord, cool looking light. Nice dial hardware and housing. Cool logo. Maybe rivaled by the LSV while fully suited up, but it is close.
Bowl design:
Wow. No extra movable glass pieces. Narrow vapor path. Doesn't get hot. Cheap to replace or stock up on. The best of the best IMO. They had mentioned a while back making a bowl for smaller amounts of material, but i don't think anyone will need it, you can load a little or a lot with equal results. I have tried 10% to 85% bowl packs, i have tried them tapped down tight, and loosey goosey. Resulted always in awesome vapor. Pull proof, or fool proof. Little to no stirring needed. This bowl will even work with bubble hash and no herb, oh my!
Oil and Concentrates:
Big advantage, this is the only vape i feel it is relatively easy to use with bubble hash and other concentrates with no herb. You can get great taste, turn it up to 3 or 4 o'clock or even all the way. but i hope you can get a little higher temp in the production unit, i like to really burn this stuff up in my Eclipse, but can always drop the load in there after its run through the Cloud and finish it off
Improvements:
I have requested a longer cord, which will be added to production unit,
Only other issue with the unit itself, and i mean ONLY other issue is the unit does get hot after prolong use. Some improvement might be made here, but i am uncertain. My suggestion, hit the off switch if not ripping for a few minutes, it only takes 3 minutes from cold or so to heat, and less for a unit that isn't fully cooled from earlier use. Some sort of rubber or silicone handle could be added to the unit, but this is not something i expect VX to do to the production unit. Maybe a slightly higher temp for vaporizing other material then herb.
Other issue, is the cool as hell hydratubes have a narrow surface to balance on. I suggest everyone invest in a tube stand, and that when VXC decides on a final price to include the stand in that price. I feel it is mandatory to protect these one of a kind master pieces then an optional add-on.
Will shoot a video eventually, but will leave you waiting for some days.
I would love to keep the SV but I have to keep the peace with my wife, promised
Haha I kid I kid
