Excellent scope, and I don't mean "for the price", I mean for a dual channel oscilloscope that is packed with features. The manual, though sparse, is well written in good English. I found the interface to be very intuitive therfore a detailed manual wasn't necessary. Sometimes when devices have few buttons, options get buried deep in menus; however, the main controls are thoughtfully laid out and easy to access. So now I will say, at this price, it's a bargain.
well, it seems to work remarkably well constraints considered, actually any problems I see are because it is digital not analog as a digital scope, it achieves everything it says it does! I have no complaints at all. it's remarkable the level of minuiturisation, and integration value for money is excellent. I will be trying more FNIRSI products in due course!
