Sold as a Single channel 100MHz Scope for less than $80 with what does come with a few flaws, feebles and bugs, which makes it really a 20MHz workable unit. But it does go to show the Chinese are hot, and going places, where manufactures in the West would never enter a market for such a bargain price.
I did a bit of research afterwards and Banggood sell what appears to be the same model as the Dainu ADS5012H for less than £54 UK!! link here.
