Worth and value is subjective, hence you're gonna get a lot of differing opinions. Only you can make that decision whether or not it's worth it. Unfortunately, IMO, for you to fully get a satisfying answer to that question, you need to either own one or borrow one for long term use - And there's the rub, to find out it'll cost you $179.00+ or you'll need a really good buddy that'll lend you their ProVari for an extended period of time.
I have 3 ProVari mini's ... are they my favorites? ... definitely not.
Do I enjoy them? ... I absolutely do.
Are they worth it to me? ... absolutely not.
Why do I have 3? ... because I can afford it and they have really good resale value.
IMHO, reading some of the opinions of members on this forum about ProVari's will likely confuse you more. I've copied and pasted a response from a similar thread about ProVari's v.s. ________ (fill in the blank) ... and it's true, they do tend to end up like this:
OP: "I'm looking to upgrade from _____. My budget is below (insert price usually at least $75-$100 bucks below the cost of a Provari)"
Provarinati #1 (usually within post #3): "Get a Provari."
MVP/Zmax/SID/SVD/VTR/VAMO owner: "Provari's are over-rated."
Provarinati #2: "Typical. EVERYTIME the haters just HAVE to chime in. Let them, they are just jealous and envious. Warranty, solid, USA USA USA, warranty, USA. You just don't get it 'till you hold it. People be hating."
Provarinati #3: "My Provari turned water into wine. Warranty, solid, USA USA USA, warranty, USA. You don't understand..."
Provarinati #4: "I thought I couldn't have children, but after I got my Provari I am expecting!!! USA! USA! Warranty, USA!"
MVP/Zmax/SID/SVD/VTR/VAMO owner: "Provari's are over-rated. They don't have VW. The Provari Mini is a $200 700mAh rip-off"
Provarinati #5: "Hater! VW is over-rated!"
Provarinati #6: "700mAh may get you 50% less vape time than a $25.00 1300mAh VV eGo twist, but what your not comprehending is that Provari Mini's are forged from the tears of Chuck Norris. USA!!!"
Provarinati #7: "You don't get it, man. You have to hold it."
OP: "I don't understand..."
The bottom line is, take whatever responses are posted in this thread with a grain of salt ... including my own.
