I bought a whack of these at their November/early December sale prices and I think they will help to reduce the 'rube goldberg' improvised nature of my current setup.
Both the balance and charge boards are ruggedly constructed except for balance board exposed male input pins being vulnerable to getting bent. When I received them I pressed a small piece of 1/4" end grain balsa into these pins for protection from hanger rash. An alternative is to keep the balance adapter cable permanently attached to these pins for their protection.
I use the I-charger 308 duo and recommend buying several of these balance adapter cables - to fit the particular charger you are using - at the same time as Progressive seems to be the only retail outlet for them.
Communication was good and mailing cost to Canada was reasonable.
