Sorry to hear about your battery.
Mines running for 2 days hunting before a recharge. Easily over 12hrs as stated & I only use the 10W Apple charger btw.
My shafts are absolutely rooted though. And after taping them to make tighter, Ive realised after today that the shafts are too thin walled and its the little silver ball locking clip button that is the culprit. Its elongating the holes on the shafts, therefore getting slop and wobbles even though they still click in. It might be a weight saver but I think if using a thicker wall shaft you would still swing it allday comfortably.
If when we can get the plug on the lower shaft that the coil attaches to, then ill be going one piece (carbon) shaft and saving the replacement shafts for travel.
But I feel for you guys like me with issues, I feel for ML having to rectify the problems, But thats what happens when you get things made in another county, along with ETAs nowhere to be known.
