    The product is really good. I am using it only as a hobbyist and it can do a lot more than I could use it for. Brilliant screen, intuitive controls, seems very accurate. I have never known more about every USB I have 🙂

    This was my first purchase at robu and it went very well. Fast shipping, good packing. Better price then amazon
