Well I have seen these being used by a few other hobbyist so I thought I would pick up a set just to see if they are as great of a idea as I think they are and to see how long they last .
Well after getting these little buggers in I believe they are a great investment but don't expect to swap these between batteries they are not designed for that and will break after opening and closing them several times . The only thing I can think of to add is I think a layer of heat shrink would be good to keep out dust and to lend a bit more strength to the case.
A great device which makes plugging or un-plugging your lipoly balance charge lead much safer and more convenient, the re-usable Balance Plug Saver simply snaps onto your JST-XH balance plug to give you a decent finger grip, no more yanking on balance plug leads!
