You should be able to get a LavaTube V1 for around £25... There is a vendor in the UK doing them for that. Add on a charger and some batteries and you are looking at around £45 or so all in.
Compare that to over £200 for a Provari and you are looking at a really good deal. (especially if you need VV now and are saving up your hard earned pennies for a Provari)
I have had a Lavatube v1 for around 4 months and just got some Ego Twists.. Which are great for me as I never go much above 4.8 volts anyway on a SR 3ohm carto.... Keep your eyes open, as because of the availability of these babies (as well as other cheaper VV devices such as the iTaste thingy) the original Lavatubes WILL come down in price as vendors try and clear stock for when the new LT's are released.
For the money, and an entry into the world of VV either of these devices will work well for you.
My minor bugbear with the Vmax is it really isn't a do what it says on the display kinda device. Plus it's only $30 cheaper than a Provari last time I looked (It may have come down in price now though) - so if you were to go with one of these, why not get a Provari??
I have heard that the voltages are way, way higher than the device specifies on a Vmax... Also, its a stacked battery mod. I'm just not sold on it as for me stacking batteries is not something I'd choose to do. Still, by all accounts it packs a real punch so it may be great for some. (I'm not bothered really by what a display states - I find my sweetspot by taste)
Having said that, The Lavatube V1 is also a little quirky with the display not showing actually what you are vaping at. Use a single coil 3ohm carto and it's built in restrictions won't be much of an issue. I started on LR cartos and it just wasn't all that great. I switched to single coils and it's a great device for the money...
Having said all this. My next major purchase will probably be a Provari, but not for a while as I simply don't need one. I want one, yes. But I don't actually need one. There is a huge difference... They seem to be the iPhone of the VV world and hard to beat by all accounts... Bloody overpriced still though I think. Knock off £30, or offer it complete with all the extras and I'll be sorely tempted,
But, and this is a big but in my eyes... Er... £27 for an end cap? Really? Cant vape that... - I can get a twist and 5 cartos for the price of a bit of steel tubing with a thread on it.... Extra £15 for a different coloured LED? Really? Can't vape colours - That's an EGO battery - Someone has seen us all coming and the worse the hype surrounding the Provari gets, the more justified the manufacturers will feel about literally fleecing people. I seriously doubt it is £180 better than my Ego Twist. £100 better, maybe.
