OK, I've now had an additional 2 crucibles tonight, so that's 6 since I got the replacement unit last week. I have to say that based on my limited experience that I'm delighted with performance of this replacement. Vapor on the first hit. On these 2 crucibles (unknown strain of sativa), I'm got 5 vapor hits on level 5 for the 1st crucibile. The 1st 4 were great & on the 5th one I could taste the popcorn undertone. So this is where I just dump the abv. OK, I thought this was the all-in-one mp assembly (known as Mk2 -- have no idea why this acronymn). But, no, this is the interim upgrade. "To clarify on the heatsink - this is not an 'all-in-one', it comes apart and reassembles just like the old one (or it should!). The parts will all look identical to your previous heatsink components but some changes have been made to materials." "Don't worry, you can still clean the mouthpiece/heatsink assembly just as you did the old one - this is not yet the Mk2 fully redesigned assembly but has undergone significant change in terms of the materials used in order to avoid the problems we experienced last year with grinding/scratching and to reduce or remove air bypasses between the stem and seal. As before, iso can be used to clean the components other than the seal and cap which should be kept away to prevent them being damaged by the alcohol." -- GhostOps (I gotta insert something here that's been bothering me -- is it an English thing to write 'heatsink & not "heat sink"? ) I don't know what material the 1st gasket was made out of, but it feels either like rubber or a combo of rubber & silicone, & is super dense & hard. But this replacement gasket is soft & pliable & less than 1/2 the density. It's comparable to the green silicone within -- it's squishy. So in essence, instead of having a 1 or 2mm gap in the back of the heat sink because the gasket material was so dense that it would push the top plastic piece up so you had that air gap. Now, the gap is like 1/2mm at most. There's also 2 bi-layering indentations in the gasket front for assumably better grasp. (You'll see all this in @SirCrackHill's pic below.) But there is a trade off: The silicone, having lost the level of density --thus being squishy) is prone to getting caught between the top plastic piece & the heat sink when I'm coupling them together during reassembly. I know I'm gonna have to be ever so careful as to not nip the silicone by catching it between the 2 pieces. It's so soft that I have no doubt that if it got caught when coupling those parts (kind of like you catch you skin in a zipper -- ouchie mama!), it would easily be torn or gouged. I guess undainty me will have to be extremely careful when assembling. I really am looking forward to an all-in-one. Here's what @SirCrackHill posted on VLF: "Haven’t tried that yet. I’ll try that out tomorrow night when I get a chance. I’m sure it’ll fit, maybe a little more snug. The gasket I haven’t had any issues with putting into the other heatsinks. The Stem seems to be a different material than the other. The tube feels heavier and thicker, it’s totally smoother out inside and out. Heatsink.. I’d have to weigh the two to really see. Seems the same." "Differences are: Stem is perfectly rounded, slightly larger Gasket ribbed instead of straight which allows for the cap to sit flush vs. up a little. Pulling stem up doesn’t pull whole assembly up Tube Inside thicker, heavier Heat sink the same" At 1st I thought the stem was plastic, but, no, it's glass of the same thickness, just better molded & a larger lip rim. Doesn't seem that it will break between your lips, unless you bite down with your teeth. That's the only diff. I see. My stem is not round, it's oval like the originals & the lengths are the same. And yes, the assembly no longer slides up when you pull up the stem. SCH's pics: Left Mk2; Right Mk1 As far as battery is concerned, after my initial 3 crucibles upon receipt, that battery I used went down to 2 LEDs & 4 or 5 days later it's still registering 2. Threw the fully-charged, Slightly Stoopid battery in for tonight's session & after 3 crucibles it's still showing 3 lights. I guess the batteries in this pack are functioning better. For my amount of usage it's mute. Swapping 2 batteries back & forth is not uncomfortable to have to do. I'm sure there will be great improvement in the next generation before the MV2 even comes out. I'd like to see the MV2 with user 18650 replaceable batteries or Lipos. I resent having to spend $60 on a dedicated battery replacement, with a 1 year warranty to boot. For $60, I'd expect a 2-3 year warranty. If you are on android, like me, anyone here on FC not following on VL, needs to be, as some members here don't partake over there & vice-versa, in order to get the whole scope of experiences, you really need to follow both threads. VLF thread link: https://forum.vapelife.com/discussi...ost-mv1-now-available-on-google-play#Item_115 MV-1 Forum link listing all threads: https://forum.vapelife.com/categories/48/ghost-mv1T There's an ios thread in the MV-1 Forum, but no posts for 23 days so I guess everyone on this platform is pretty much squared away. I do have 2 important things to say, well, at least important to me. First, if anyone who purchased one of the 1st 1200 - 1500 purchasers who feel they are not getting satisfactory results from the vape after the the ios & android updates, & your gut tells you it's not functioning right, then you should reach out to GV to request a replacement. No reason anyone should have an unsatisfactory experience with a $300 vape now that the updates are being incorporated in the new productions runs. Secondly, I'd really like for us members in this thread to come together around this vape as a real community. No more snide remarks & bickering. Let's try to help each other better our MV-1 experience, and share our experiences. I want us to start having some fun on this thread. PS - Here's a great pick SCH took of the rose gold: @SirCrackKillaH, you live in Vegas? And, do tell us what those new satin colors are that are coming out? And exactly what accessories you've seen. What do you think of that case that's gonna house the MV1? Is it rubber over plastic or just plain plastic with the silicone inside exactly like the crucible holder? Come on, SCH, give it up!

OK everyone, thanks for listening, or should I say tolerating me? I'm off to finish the video. BTW, can anyone tell me what OG stands for? Original what? Thanks!
