I have the new stainless
tank from Arry and so far I'm happy with it.
The tank is the ACTv4 and I'm using Boge 2.0 LR on a SB with a 3000mah battery and so far it's working well. I really wish the tank had a window so I could see how low the
juice level was but it's not a deal breaker since the tank doesn't leak but I do have to unscrew the cap to check fluid level once a day or whenever I start to lose flavor.
As I said, this is a new tank for me so only time will tell how it handles use/abuse but so far things are looking pretty promising!
