I have for sale a zefon z-lite testing kit. It came with a bunch of used construction tools that were given to me and I have no use for it. I plugged in the pump to test it and everything seems to be in working order as far as I can tell. If interested then please make me an offer. I am located in Charleston SC and can work out shipping or meet locally.
I will give you a $100 for it.
I can do $150 shipped.
