Review on Klein Tools VDV999 200 Replacement Continuity by Mark Young

The device works and can be tested, but is not a full replacement. The replacement should snap onto the bottom of the Lan Scout jr like the original. It's not like this. They have a smaller form factor. They will be lost if you don't keep them together in one suitcase. They work, so if you need them, get them, but find a way to protect them or find the right device.
