A very good function generator, I have tested this extensively. It really offers an incredible variety of signals, over 150 signals are actually stored. It is also very nice that the two channels work completely independently of each other and that many types of modulation can be used independently of the channels. The sweep function for wobbling, i.e., for automatic frequency sweeping, is also excellent. The signals are very clean and the operation is remarkably simple.

Very high quality arbitrary waveform generator. Its appearance and ergonomics are excellent (see attached photos). The menu is very easy to use and very intuitive, on par with much more expensive instruments by Tektronix. Very small form factor, and can even be powered by a USB power bank, making it portable. It has 2 independent channels and can go up to 70 MHz. I still cannot believe that this little generator only costs 160 €. I haven't actually tested the signal quality using an oscilloscope, but I believe it will be fine for a hobbyist or even a semi-professional laboratory. Well packed, and only took 10 days to arrive in Greece. I'm extremely satisfied with my purchase. Highly recommended product and seller. Thank you very much.
