Mech sauce has become my new go-to budget juice company for when I don't feel like spending $18+ on 30ml of juice. I see a lot of complaints that they take about a week to process orders, but that's totally okay in my book. Its a small father and son business with minimal overhead and very few employees. This accounts for the insanely low prices they're selling their juices at. I'll take cheap, delicious juice over mediocre, quickly delivered juice like Mt. Baker. For the people who complain my advice would be to simply place an order ten days before you need it.
As far as taste goes its fantastic. Super creamy and flavorful, even at max VG. I am a little weary about AP/DP since many of their juices are creamy/custard juices, but that's another discussion. The customization on this juice is absolutely fantastic as well. You can choose any amount of nicotine rather than integers of 3, which makes weening yourself off nicotine all together no problem.
So to wrap things up: Yes, they have slow shipping times, but the price and quality of juice absolutely make up for it.
