OSCIUM iMSO-204x: Smartphone / Tablet Oscilloscope, Universal Platform Support (Including iOS, Android, PC, Mac), Portable, Intuitive, No Software Subscription

This o-scope was a great add to our lab where we don't need a scope regularly, but when we need it, we need it. The low investment and easy to use interface gives us what we need for the times we need it and have had no issues with capabilities or accuracy. Having a calibrated instrument on hand is also perfect for maintaining audit requirements without having to spend a lot on rentals. On top of it all, some of the best customer service I've ever experienced.

It's difficult to judge the hardware because the Oscium iMSO control software for both iOS and Mac is so buggy that it is unusable for many functions. The logging function, in particular, does not work properly on either platform. The Mac version has other bugs that should never have passed Q/A - for example the help screens and file lists don't scroll properly. The log files get dumped into iCloud/Documents with no apparent way to choose a different directory.Oscilloscopes, even expensive ones, have traditionally had a bad reputation for their user interfaces. This device was touted as being the future of oscilloscope knobless GUIs, and instead it takes bad GUI to a whole new level. As a result I have neither the time nor the energy even to attempt to run the hardware tests that I had planned. It's on its way back to Amazon.

This oscilloscope is very user friendly. It provides the basic functions of a higher level oscilloscope but cheaper. It is easy to use and take anywhere. Over all, I am very satisfied with it.
