My first cable tester, I use it at church. No-nonsense cable tester. Very easy to use and testing existing cables is a breeze. Multiple jack types for all common cable types: XLR, 1/4" jacks, 1/8" jacks, USB, MIDI, RCA, Ethernet, speaker. "Intermitent" test for cables (testing of temporary disconnection) is gold. Extremely happy with purchase.
