It's a sad situation, when these models came on the market more than a year ago, they was very promising. In fact their Chinese programmers are trying to fix reported bugs, but when they are in hurry, maybe not on this model only, things mess up and this lead customers to dissatisfaction. Unfortunately this guys from Hantek are not enough open minded to accept the open source model. If the firmware was open source it would be great, there are so many talents between us, that DSO2x1x could become the perfect cheap oscilloscope. But when something great and open sourced comes from Europe or US, like the Arduino and thousands other, the Chinese factories and sellers on ali, banggood and ebay are happy. These days even Microsoft accepted the open source model, but our Chinese comrades are a way behind.
So everybody is welcome to give a vote on this poll:
