They didnt give a time frame, but they did say its in the process, I will go back and find out more info.
I am keen on picking one up in the near future.
Looking online a see a few being sold with 220-240v - so not too sure what is going on there.
I hope they get it up and running soon for you!
while it may work and work reasonably well, their claims are inconsistent with science based testing. First, 120C for 90 minutes in itself is too long and THC will degrade! 252F for 27 minutes will give 100% decarb. Decarbing in an oven is not the most accurate way, but you can improve on that. One of the best ways is to use a pizza stone and a GOOD oven thermometer. I find my oven set to 245F is actually at 251F. The pizza stone keeps the heat applied to the material even as the stone is slow to heat or cool. Using my infrared thermometer, the stone varied between 250 and 254 degrees. I run 26 minutes.
That said, the machine does look interesting. I'd like to see independent testing to prove their claims, I'm not convinced at all.

Thanks! I have been looking for where you had posted that. I use the same time and temp.
Actually, the best method for decarb is a hot oil batch. skunkpharm research uses an old fondue pot. The oil holds the temp very consistent. I'm considering picking one up and trying it. Deep fryers run too hot and oil in a stove top pot is too dangerous. Need to burn your house down? "Forget" a pot of oil on the stove....lol!
I'm a sucker for a coupon code. I have little to no experience but your method is solid based on the research. I found some posts that did some independent testing on the Nova/Lift. Go to page 12. In the 90 minute run time there is a 20 minute warm up to 240 degrees and then a 20 minute cool down so the main feature is keeping a very consistent temperature for an hour.

This is also another cool post from someone I found on wakenedbake. This guy went deep!

Decarbing Frank’s Gift Cannabis
I’ve been searching for a reliable way to decarboxylate medical cannabis for a while now, and there seems to be no consensus as to exactly how to do it. Different websites and forums all have a different take on the best temperature to use, how long to heat it, how to prepare it etc. My search finally led me to a British patent for a process of liquid CO2 extraction of resin from cannabis, in which they mentioned how they decarbed their samples and, most importantly, they documented the resulting lab analysis of 4 different amount of time and 3 different temperatures, and the differing results on THCa, THC, CBDa, CBD, and CBN. To me, this is a wealth of information. Here is a link to the patent:
http://www.freepatentsonline.com/7344736.html
The 3 temps are in Celsius and translate to Fahrenheit as follows: 105° C = 221° F, 120° C = 248° F, and 140° C = 284° F.
My takeaway from this long, very technical paper is the following 2 sentences:
Chemovar producing primarily CBD is 1 hour at 120° C. or 0.5 hour at 140° C.
Chemovar producing primarily THC to minimise CBN formation, is 1 to 2 hours at 105° C. or 1 hour at 120° C.
Translation: heat your cannabis in a 120° C (248° F) oven for an hour and you are good to go. Regardless of if your cannabis is high in THC or CBD this will work very well. So I did just that (sort of) and then had the cannabis analyzed at OG Analytical in Eugene, OR. Here is what I did, the lab analysis of cured Frank’s Gift bud, and the decarbed Frank’s Gift bud.
In the patent, they say it is preferable to dry the herb at a lower temp, then decarb it at a higher temp, but since I had put a pizza stone in the oven to try for a more even temp, I dried it and decarbed it at the same temp.
5/10/16 I started with 36 g total; removed 1.124 g for analytical lab testing. That left @35 g before removing stems, @ 34 g after removing .9 g of stems.
9:00 AM I put a 16″ pizza stone (9.5 lbs./4.3 Kilograms) in the oven and preheated to 250° F. I used a Farberware oven probe (laying on the pizza stone) to get an accurate temperature. It showed that it took @ 90 minutes to get up to temp.
I was aiming for a temp of 250° F, but since my oven fluctuates about 20° F, I could not achieve this. After almost 3 hours of screwing around with the oven, turning the temperature dial up and down, trying to get it to a stable temp, I gave up, and settled on a setting of 245° F.
I broke up the buds into small pieces (it was very sticky), put it on an aluminum baking sheet, and put it in the oven at 11:45AM. I left it in the oven for 20 minutes to dry completely. It was not sticky at all after drying it. I crumbled up the buds in my hand (very easy) and wound up with mostly powdered bud.
I returned the baking sheet to the oven and waited until the oven probe said 250° F, which took about 15 minutes. I left it in the oven for another hour, removed it, let it cool down a little, and weighed it. It now weighed 28 g, so it lost about 6 g of moisture (17.6%). I took out 1.15 g for the lab. Here are the lab results:
Before Decarbing
THCa = 4.8%
Δ9-THC = 0.9%
CBDa = 9.9%
CBD = 0.6%
CBN = <0.1%
After Decarbing
THCa = <0.1%
Δ9-THC = 4.8%
CBDa = <0.1%
CBD = 9.1%
CBN = 0.2%
I am thrilled with the results – all of the THCa got converted to THC, all the CBDa got converted to CBD, and very little of the THC got degraded to CBN. Not too shabby.
Next time I wouldn't mess with the oven temp. I would just set it at 245° F and leave it alone.
If you look at Table 5 in the patent, you'll see that there is quite a bit of leeway in time before the THC starts to seriously degrade into CBN, so leaving it in the oven for 1-2 hours at 250° F would not degrade very much THC (4.1% after 1 hour and 6.7% after 2 hours).
Miscellaneous notes: Franks Gift organically grown outdoors, harvested on 10/4/15, dried in 50% humidity, 70° F temp for 5 days (stems snapped at that point), then placed in 2 quart canning jars with a 62% Boveda pack for curing. It has been in the jar for 7 months.
I hope this is helpful.
