Several have asked if the ProVari is just “assembled” in the US or “made” in the US, so to address this questions here are some details: The ProVape-1 and ProVari are actually MADE and ASSEMBLED in the USA. Parts - Machined right here in Monroe, WA. We use US-made stainless steel bar stock to produce the tubes, top caps, bottom caps, contact pins, etc. Everything is done on our machines locally. No outsourcing. Bare Circuit Boards - Manufactured in Illinois. We do not purchase the circuit boards from China due to their poor quality. While the circuit boards are more expensive to produce in the USA; this is the heart of the system and it’s important to us that they are the best quality we can get. Each PCB is electronically tested before it ever sees components. Electronic Components on Circuit Board – these are the only parts that might come from outside of the USA. Some of these parts are simply not made in the US, so we can’t get them from a US source, even though we would prefer to. We use components from Japan, Korea, Taiwan, Malaysia, China and the USA. Component assembly - Components are soldered onto the circuit boards at a facility outside Seattle, Washington. After getting components installed, the boards are tested several more times at our Monroe facility to ensure they are ready to ship. We test each one multiple times to give you the most reliable product you can get. We don't cut any corners when it comes to quality control, testing, and component selection. We love to hear all the positive comments about the ProVari and PV1. Thank you for your support!
