These units are a pain to set up which is not Banggoods fault. The Hantek drivers are not verified or signed for Windows 10 use, they have certificates but Windows does not recognise the certificate. My first one stopped working on the second day - replacement was sent by Banggood who were brilliant and very helpful. Replacement unit arrived ahead of time even with COVID-19 restrictions. Second one is now working perfectly and is exactly what I expected. Do not expect to use it on mains voltages (without buying replacement probes with 100x setting) and also find a way of isolating either the project you are measuring or your PC (running a laptop on batteries would fulfil this requirement). Save yourself loads of hassle and DO NOT USE the Hantek software and drivers. If you have trouble - all you will get from Hantek is redirection to alternative drivers none of which work. Don't believe me just visit their forum - loads of folk just like me having the same issues and redirection. Use the OpenHantek software and driver - it is really what the Hantek software should have been in the first place. For small electronics projects this unit is ideal especially for the price. It produces clearer display images than the small 138 units (which are great fun) and displays measurements on screen. Printer output is configurable as is the screen, which when using OpenHantek can be configured to look like the old pale blue CRO's if that is what you want. Storage works although it stores everything and you have to search for the bit you want - this may be down to the operator. I am using this to teach my daughter electronics, and successfully demonstrated full AC wave, half wave, rectified wave and measured ripple on a rectified circuit with capacitor smoothing. Overall I am pleased, the unit is as good as expected, Banggood support service is absolutely brilliant, but Hantek have let themselves down with the software hence the 4 star review. Would I buy another? Probably.
