I have been spending a lot of time testing the security of many IoT devices. Getting access to JTAG or UART pins is always a chore. These little probes make it a breeze to hook up various tools like a logic analyzer, oscilloscope, or a host adapter to even the smallest ICs footprints.
These we shipped quickly and the function is great. I was able to solve an ongoing need immediately by measuring the same point on two different boards for comparison. I even upscaled the stand a bit with a magnetic base digital dial holder I had.
