Provape has always marched to their own drummer. They enjoyed so much success setting new standards with the original Provari that they may have drug their feet before finally introducing the P3 version.
Provape has always appeared to target a certain market, IMHO. The vast majority of vapers worldwide are "tootle puffers" -- normal resistance, low wattage --- so Provape seems focused on that segment of the
vaping population. And they do what they do very well.
Vape shops and e-cigarette forums tend to attract vaping enthusiasts and hobbyists (hard core vapers, cloud chasers, et al), so much of the trends and focus with these groups has been on sub-ohm vaping and high wattage devices. In reality, they are the minority worldwide. Provape has always been about safety as its number one priority, so manufacturing a device that can sub ohm and put out more power than the average vaper needs has never been their priority. With great power comes great responsibility. Has this philosophy hurt their potential sales? Maybe, but I imagine Provape sales aren't exactly hurting either, especially online sales.
Provape focuses on building a device that has reliability, dependability, better than average quality control, high manufacturing detail, durability, a better than average warranty, and a well-deserved reputation for life long customer support. In the rare event a Provari dysfunctions or breaks, you'll get it back good as new in a weeks time.
Is a Provari designed for every type of vaper? No. A P3 compared to many of the current high wattage box mods currently on the market is going to appear over-priced and weak in the power department comparitively. But it still suits the "average vaper" profile well, and especially if the consumer places a priority on the characteristics in the previous paragraph. The average vaper (via multiple recent poll results) vapes between 10 - 20 watts, a range that the P3 suits.
It's not really fair in a price comparison, but my sister recently purchased her first vape setup while we visited a vape shop together. I had offered her one of my Provari 2.5 to use until she had experience to figure out what she wanted to buy. She thought it was too big and heavy, and chose to buy an Eleaf iStick 30 watt instead, a popular and inexpensive beginner setup.
Well, that iStick stopped working a week after purchase; some sort of defective board issue. The shop agreed to replace it, but she had to physically return it. She lives 120 miles roundtrip and wouldn't have the time to replace it for several weeks with her busy schedule, so she bought another iStick online until she could replace the first one. Well, she dropped and broke the second iStick after only 2 days. I couldn't help thinking that had she decided to use my Provari in the first place, none of that would have happened.
