Incredible device, especially given the price. Initially worried about the small screen size and upgrade to BenF SW. Screen size is easily legible and the upgrade was done easily thanks to Stickboys review and follow-on discussion. Minor issue with the probe input not being standard connection and does not retain the probe very well however it is very usable. BTW, for those who shy away from flashing firmware, the OEM firmware IS usable if you take some time to figure it out, just not as intuitive as BenF.
Excellent product once you upgrade the firmware to Benf. My upgrade, once i found the correct version of Benf, was a snap. Don't let the small screen size and menus fool you into thinking it is a toy. The DSO Nano is a very nice single channel scope. I find more and more uses for it as I get familiar with its capabilities. SainSmart is a great vendor and would not hesitate to order again from them.
Arrived on time, works as advertised. I only test line power, clocks, oscillators, timers and generators from 0-400 Hz. Will suit most needs for industrial, automotive and power and generation equipment. A great supplement or portable alternative to your bench equipment or as a cheap interim alternative while you are researching and saving for a bench type oscilloscope and the price is right. I was surprised how easy it is to set up and use. Good for beginners and project board enthusiasts.
I admit I am not well experience with oscilloscopes. Works OK or great for the price. Instructions for operation could be a great deal clearer and detailed. If it is possible to retain settings when turned off I never figured it out. Screen capture is a life saver. Suggest download instructions from the manufacturer. At least easier to read. 7/22/15 SainSmart really does stand behind what they sell. I had a small problem with this and they quickly and totally made it right. 6 star support and service!!!
