I would also say, as other members, the batteries might be the problem if anything else is fine. I just sent 2 OGs to Finland because of bad performance.... I had 3 batteries I always rotate since 5 month and I'm a heavy user, at least 5 bowls per day. So I thought they were still okay...Nothing seems broken or dented, nothing sounds broken inside. What can be causing this?
Before I sent both devices to Finland and cleaned them, I wanted to use them a last time to be sure it's the right decision.
I used a fresh vtc6 battery I got last week and what shall I say? No more bad performance. I already calibrated both devices to maximum so I shit my pants because of the fucking huge clouds I suddenly got.
Maybe it's a good idea to have another spare battery, which is not in your daily use circle. With this one you can check if it's your tinymight or your old and worn out batteries fault, if the clouds are missing.
