This is too hard to call. Everyone is going to have there own opinion. Everyone has to deal with effect of what they do.
For my wife and I, we try to buy Made in USA, anytime we can. It is a personal preference. We do this, because:
At least for a time the money stays in the States.
It helps to keep an American employed.
It supports my country.
That being said. I will buy a product that I like, no matter where it was made. But it has to be well made. It may cost me a little more, but I only plan on buying it once.
I have a Provari, but I also have a Joyetech Twist and a Sigelei Zmax flatop. As mentioned before, Zmax is kind of original and so is the Joyetech. If they prove not to last, I won't buy from that company again.
I have carto tanks, all made in the USA. All my juice is Made in the USA(just 3 juices).
My Protanks are made in China, along with the Davide and DBox BCC tanks.
My Luer Lock Syringes are made in Thailand, but it was invented by Becton Dickinson, an American Co.
But I bought all these products from Online vendors in the USA or from B&M shops. At least my money was in the states for a while, and helped employ someone.
I don't have a Mech Mod, so I am looking at the various models. I like upper side button mods. Easier on my poor fingers. I really like the Atmizoo Roller. Sleek and simple. I have looked at a Atmomixani 69, very similiar. Yea, both made in Greece. I don't really care for the more exposed button on the 69.
I also looked at the Sigelei #20 roller clone. But you know what, it is on its 3rd version, and it still has problems.
So I will probably wait to buy the Roller. Fits my desires a little better. Good customer support, spare parts, and someone to speak with about it. It will be another month or so before I buy one, unless I find it used. I have a vape budget. It is the money I would have spent on cigs, which was approximately $220 a month. I mean, I would have spent this on cigs anyway.
When I have the money I buy the product. No money saved, no devices. There is a B&M near me that has the Roller. It comes to about $20 more(1/3 of a carton of smokes) than ordering direct from the company. But someone is employed, the sales taxes go to the local town and state, the person employed pays taxes, maybe buys a product made in the states, etc.
Just my 2 cents.
