Clean and simple device. has all type of "small" signal connectors I can imagine and simply tests a pin to pin continuity. the beautiful thing about it is all connectors pins are parallel, so if you have let's say a XLR 5p to 3p converter or a TRS/TS jack to XLR or RCA, you can still test it! which pretty much covers it. in case your type of connector is not on the tester (Harting/Soca etc.) you could still test with the two probes which are provided with the device. it takes a standart 9V battery and it lasts forever, so no need to worry about that.
the size of it is relatively small, for the amount of connectors offered, it's light and you can just throw it in with your toolbox.
the build quality seems sturdy enough and I hadn't had problems with it breaking on me. I do treat it nicely so I can't guarantee it will survive very rough handling.
I found it a great problem solving/preventing tool on the field and would recommend it to anyone that asks me about a cable tester.
there's nothing I've seen in this price category which comes even close to it.
bottom line: Buy it now!
