fast shipping to poland through inpost courier, came in about 3 days, i think it is upgraded from factory to 200Mhz couse it already has 2ns horizontal scale option, fan is quite noisy and works constantly, but i think it can be solved by soldering lower voltage regulator ca.8v instead of 12V. I did firmware update and downloaded PC software for the scope, software is like meh, quite outdated, but it works. Havent noticed any firmware bugs yet. Case plastic is of qood quality, screen matt, big and high resolution. Saving to usb works really nice. Line seems quite noisy compared to rigols, but u need to have in mind that it only costs 240 USD. Considering its price range it is absolutlly magnifficent piece of kit and a huge upgrade from my previous dso150. Overall im very satisfied with the purchase. Really recommend that scope.
Fast delivery, excellent product
