One thing that I do like about Evolv (among several) is that they will support their boards and have a good reputation for fixing their products. I've read nothing but good things about Evolv dealing with board issues. Then again, the repair process should be straightforward. If it's the fuse, replace it. If it's the board, replace that and return the now working mod to the consumer. Save the board and repair it (if it can be) at your leisure, and use it as a refurb part as long as you trust it. That will allow fast service time and a happy consumer.
Not much different than a computer. If your motherboard goes, are they really going to rebuild one in a Geek Squad repair center? No, they'll swap it out and return the failed board to see if it can be rebuilt and used as a refurb. That's just the nature of consumer electronics these days.
Evolv have been very good to me in regards to problems, the first DNA200 I got for a fantastic price from gearbest-when it arrived and was not working correctly, to fail the very next day, and gearbest not helping, I was gutted. But, Evolv was very helpful, and repaired the device for me, I just had to pay for shipping.
Then there was an error with gearbest as I had opened a paypal Dispute, so I got the money from paypal, then gearbest refunded me-during this time I had been speaking with Hotcig, and they also sent me a replacement V2 without my knowledge, it just turned up! This also failed though lol, and again Evolv was very helpful and repaired it.
After all the worry about losing a fair bit of money on a mod, as this process took about a month+ in total (I didn't speak to Evolv until near the end of this period) each device ended up costing me £27.50, which I am very lucky for.
However, my other DNA200's (The Wismec and a Lost vape Efusion) worked perfectly from the beginning, and I see hotcig now have the DR200, I feel in a way the V1 and V2 was basically a payed for Beta model.
I agree the repair process should be straightforward, as it luckily was in both my cases with Evolv directly, I understand different companies vary though, from Vaporshark which is meant to be very good, to the other end of the spectrum.
