eburman At first I was disappointed. The waveforms were jittery and unstable. But It became clear that my switching 'wall wart" powers adapter was at fault. I tried another one and the problem persisted. Then I tried a 9V battery and performance was very good-->stable waveforms. Next I tried a linear power supply. Also very good. I notice that the square wave output tends to distort the sine wave output somewhat. The on and off transition points of the square wave make a glitch in the sine wave.

Easy to solder, Works as expected. Read other comments to build the case: little screws are not holding anything, they're used as spacers between the bottom of the case and the PCB. Square signal is not sensitive to the Amp button, it always sends a +5/-5V signal. Triange/Sine can be very sharp, but also quite noisy depending on effective power (9-12V), the Amp and frequency.buttons settings. Beware
