I've just returned home with it (good to meet you Tom), so if you can PM me your details, I will forward it on as soon as I've checked / fixed my VIS motors.
I currently have it and the address for Rockey5uk2001 to next send it however I'm not entirely sure it is working properly so also been in contact with KevG about it going back to him for checking over.
I've had both my motors refurbished so they should be good, hence my uncertainty about the tester itself.
