Can we talk about how those USB avionics testers at Oshkosh last year were totally useless?

I was at AirVenture in July, saw a booth selling this $400 USB multi-tester for troubleshooting nav/com boxes. Tried it on a King KY 97A in the shop back home, total garbage. Gave me false readings on the audio squelch and said the unit had a bad crystal when it was fine. Swapped back to my old Fluke scope and a manual wiring diagram, found the real issue in 20 minutes (a corroded pin on the backplane). Anyone else ditch those fancy plug and play gadgets after a bad experience?

Tbh stick with the Fluke and a schematic, those all in one testers just complicate a simple fix.

Learned that lesson the hard way after chasing a ghost ground loop for an hour lol.
