Wish I never lost the one that came with mine. But this is a flawless replacement...... but they gouge the price.$500 meter isn't worth a thing if you don't have a mapperworks better then expected, had to replace my original as this one had bugsGreat productThe unit was a nice price .Great!I lost my wiremap adapter. I've seen the inside and not sure why it costs so much. It's just a piece of plastic with some wires and connectors. But without this adapter, your main Fluke Microscanner is basically useless.This item is necessary if you have a Microscanner2 or a CIQ-100, it is the receptacle for the other end of your cable. If you lost of damage your original Wiremap, then this will be your correct replacement.I think that those tabs are a little bit fragile, i've seen many of this unit's case broken or cracked.It is ultra overpriced by the manufacturer, but it is mandatory to make your unit operational again.I do recommend you to avoid damaging or loosing your original Wiremap !Works good
