Hantek DSO5102P 100MHz 2CH Digital Oscilloscope 1GSa/s Real-Time Sample

I have been wanting an oscilloscope for many years now but didn't pull the trigger until recently, when I needed to look at the wave form and amplitude of a rapidly changing DC signal. In terms of using the oscilloscope for this purpose, it has been very valuable and very capable. It helped me to make data-supported decisions. I also like the built-in help menu to explain the various features. This has been very useful. The knobs and switches seem robust enough. No complaints.I do not have anything at my disposal to measure the accuracy other than measuring steady state DC voltage and comparing against my multimeters and DC PS. These tests were fine. For a hobbyist like me, I have been very happy with the Hantek.

It is a good value and very accurate scope. The fan is a little noisy/

I have a very similar model (DSO5202B). After a few years the internal time/date clock didn't retain its setting when off. I eventually found out that there is a button cell/CR2025 on the main board (not mentioned in any document I could find). There are 4 screws to remove the cover (2 under the handle) and 5 screws to remove the metal cage around the main board. Correct time/date is not a huge deal, but if you save the screen to a USB thumb drive the file time/date is the only way to differentiate between current and previous files. Plus the time/date appears in the screen capture which also helps to identify them.
