Its a fine mod, nothing amazing but it is the smallest and lightest dual batt mod I have. I've been half tempted to get a matching AL85 just because. The firmware is nothing short of a nightmare to update but at least the menu is friendly and easy. I put it on par with the SX chipsets for ease of use.
smok is putting out a ton of products and none of them so far have made me scratch my head on why they made it. I am also looking forward to getting my hands on a Osub 80 baby as I prefer single batt mods when going out and about.
I have an AL85 as well. Nice little mod, but my main reason for getting it was the form factor similar to a Pico but able to hold a 25 mm tank. They're now coming out with a larger Pico to compete. A toss up on which one you would prefer. I do know the long term history with my Picos has been outstanding, but as always, a new model is no guarantee hat will still apply.
