well I used the bonepack in my reloader yesterday, flawless all day, switcvhed on about 9am, wasn't turned off until about 15:30, put 3,000 rounds through the marker, so aside from the hassle getting the darn things to charge it's all good.
There's been a fair bit of hassle in this down the line but now they're here and I've used it I'm quite happy, so fair play to Chris for dealing with all the aggro.
Update:
Got some 3.15amp quickblow fuses, it's a little temperamental and has blown one of these but this was as part of my testing process so generally speaking all seems OK, using one of the race pack connectors and a 9v snap connector I've managed to build a working adaptor before I start work modifying the original.
