Review: Good ethernet test. - I bought this because I lost my fluke and needed something but not as expensive. Over all I'm happy, as I didn't really expect much from the price. The tester is more rugged than I thought it has all the same tests that the fluke had done and screen looks similar when testing. This has a 3 position switch one for scanning. This if for use with probe to locate wires it produces tone that probe picks up. Second it cable testing it does ethernet and coax and #3 is poe. When testing twisted pair you can test individual pairs. The fluke is a bit more responsive in how fast it aquires info. But so far this is working out great. It is a little bigger than my fluke was but only in length by maybe half inch. So far this has been working well for what I need and I got the added probe with it allowing finding buried wires a plus. I would recommend.
