Yes. Night and day.
It used to be but now the V2 is out and it handles them fine. The Buzz Pro is a good device and will handle anything that you put on it...but thats not necessarily a good thing for someone new to vv. The Provari will protect the itself (and your carto/atty) by giving an error code if you try to try to vape something at too high a voltage... then you will know to lower the voltage. The Buzz Pro doesn't care, it'll do anything you tell it to do, whether it's a good thing or not. The Provari has a led readout that will tell you the exact voltage, the Buzz pro has a wheel with (I think) voltage marked on it. The Provari will tell you the resistance of your atty or carto (don't try this if they're dry or they will fry) The Buzz Pro won't. NOTE I do not own a Buzz Pro and I have the upmost respect for the device. I just think the person using it needs to know what they are doing and what they are asking it to do. You can't go wrong with either device.
The mini is the exact same thing.. just smaller and uses smaller/different batts. The full size with the extension cap uses 18650 batts, the full size without the extension cap uses 18490 batts.. The mini with the extension cap uses 18490 batts and is the same (I think) size as the full size without the extension cap. The mini without the extension cap uses 18490 batts and is the smallest size. The larger the batt, the longer the vape time. I'd love to get a mini but I don't know if I want to sacrifice batt life for a smaller size. (But when the black mini comes out.. I can't make any promises LOL)
I use the full size with extension caps and 18650 batts and am very happy with the vape time I get.
The full size provari without the added extension cap is approx 5 and 1/2 inches tall with a dct tank and a drip tip. You don't have to get the extension cap and use the 18650 batts to get good batt life. with the regular size Provari and the 18490 batts you should be able to vape all day. I was using LR (1.7) cartos (because I had quite a few of them and liked the size compared to the shorter boges) but then the xxl 3 ohm boges came out and I can tell a big difference in batt life. I bought the extension cap because I already had 18650 batts (left over from my Lava tube phase) and didn't want to have to purchase more batts.
wow.. what a difference in size taking the extension cap off and putting the regular cap on! But anyway.. I just don't want to have so many different sizes of batteries laying around. I use a couple vv box mods along with the Provari so all I have are 14500s (for the boxes) and 18650s for the provari. If I hadn't already had 18650 batts, I wouldn't have bought the extension and just bought the 18490 batts.
The big difference between a vv mod and a regular fixed 3.7 device is regulated voltage. Whatever I set my provari at.. it will stay at the exact voltage until the batts need recharging.. I used to use cheap 3.7 box mods and the voltage would continually drop as the batts discharged. You said you only want to buy ONE more... IMO the provari is all you'll ever need. (until something better comes along LOL)
That the Provari is somehow protecting the user by not handling lower ohms at higher voltage is bogus. Provape came out with the v2 regulator because it was a recognized weakness.
Provari v1 had a hard current limit of 2.5 amps. Pretending that this was some kind of intentional bound is simply not true. It was a limitation of the particular regulator they used, not something people were thrilled with. You could get a v1 up to 15w output if you used a 2.4 ohm carto or atty at 6v, but people wanted to be able to get to the higher power using lower resistance at lower voltage.
The new provari v2 addresses this with a regulator that has an output current limit of 3.5 amps. It loses a little in terms of absolute maximum power output available, but gives better power options at lower voltages.
The provari v2 basically gets you to a working power zone (Max Watts at given volts) that is at least close to what the notcigs products have already provided for 9 months. V2 does have a bit higher max voltage, though I don't know how many people work in the 5.5 - 6v region. V2 also added a bit further low end range, but i've never heard of anyone buying a high performance vv to vape down in the 2.9 - 3.2v region.
If someone wants an LCD, nothing wrong with that. Me, i'm an engineer, but I vape to replace smoking, want my pv to provide a simple interface and consistent performance. Notcigs pro are very rugged, high performance vv, notcigs was the first vendor with production vv.
The provari is a really good device, high performance, excellent reputation and customer service.
The notcigs products have the same positive attributes.
Preference as to the user interface truly is subjective. If you like numbers/buttons/lcd, provari; if you prefer simple elegance, notcigs. Neither approach is inherently right or wrong.
Sorry if my prior post was pushy, but the v2 improving how provari handles lr means that it operates in the same power zone as bp, inconsistent with saying it is somehow doing something special to protect users from using higher power
LOL.. I knew that no matter what I said I would get a Buzz person riled. I wouldn't recommend either device to a novice user. I like an led readout that's why I went with the Provari but I looked at the Buzz Pro long and hard. They're both beautiful, quality devices and you would be happy with either one.
I'm not familiar with the device you're using now so I can't comment on whether it will hit harder or produce more vapor. VV means you can turn up the voltage and get more vapor and a hard "hit".
