Just wanted to report back my experience with Fasttech. They were one of the only places to have a coupon that worked for anything on New Year's Day (10% off). So I ordered a Pico 75w from them for $23.25 shipped.
Ordered on January 1, shipped January 4, received January 22. So not bad. Took about 3 weeks. I haven't tried it, and don't plan on trying it. Just kinda an OCD thing. I like keeping it sealed until I need it.
One thing I did do was cut a slit on the packaging and checked the authenticity/security code. I had read through google searches that Fasttech was known for removing the stickers a few years ago because they aren't an authorized dealer, but mine showed up with the code intact. Everything checked out authentic, and it was the first and only check of the code. So I'd say that was a pretty good first experience with Fasttech.
I'm not really active anymore. Got the mod I've used for the past 2 years, with the tank I've used for the past 3 years, with the juice that has been my ADV for 3 years. I've got spares of the mod and the tank, 240ml of my ADV, and enough koh gen do to last me 10 years.
I'm actually not as concerned about a backup as I was before because there appears to be Chinese manufacturers still making clones of them, plus the Pico 25 and Pico Mega if absolutely necessary. In the end, it's just a box mod. I would deal with something else if I had to. But I'm glad to have a spare.
