Its quality is usable. The reason why it got 2 stars from me is because it doesn't have huge shortcomings. 1. The USB is only for charging, not for data connection, in other words, you can forget about the firmware update. 2. There is no baseline zeroing in oscilloscope mode. In other words, the DC offset must be taken into account and corrected by yourself. I bought two devices, one with -900mA and the other with -1.5A negative DC offset. 3. What I think is its biggest shortcoming is that it does not have Single and normal triggers. And since you can't update the firmware, you can forget about it. The accuracy of the DC is good, the part of the multimeter is of the usual good quality from Owon. The display is clearly visible, but the surface of the oscilloscope is smaller compared to the HDS120, the height is the same, but the width is almost half. The shortcomings of the HDS120 can also be discovered here.
