Review: Hantek DDS 3X25. Anyone own one?

What's the point of buying an arbitrary waveform generator for just the sines? A dedicated function generator or even frequency generator will have a cleaner output, better amplitude control and proper controls.

i bought a sine generator up to 100MHz for $100++, and am not an audio people, and am not a true professional engineer. + other bonuses mentioned. - standalone"liness", lcd screen and low noise.

True, but I'm not sure where you get a 20MHz function generator (with the added counter and digital IO stuff this thing has) for ~$150... and it's the proper controls that cost much of the money.  This has 6 digital inputs... for a quick and dirty FG with set frequencies, it would be easy to rig some controls to the front of the unit and write some simple control software - for example:
1 bit for push-button function select: alternate between sine, square, triangle, ramp, noise, am/fm, exponent, etc.
3 bits for range: 1Hz, 10Hz, 100Hz, 1kHz, 10kHz, 100kHz, 1MHz, 10MHz
2 bits for multiplier: x1, x2, x5 ,x7.5

I guess my point, as saturation pointed out, is that the DDS-3X25 is a cheap hacker's delight  :)

Just bought the DDS-3X25... now I just have to wait on the long trek of China Post  :)

saturation:
Great! Welcome to the club.  Please give us feedback also on the buying process and what the package was like when you finally received it.  Enjoy.
