I don't mean to disparage the Labrador but I suspect it will be more use to people who integrate it into some other project than to those who need a scope.
The "All Sun EM125" Multimeter+Oscilloscope (https://www.aliexpress.com/wholesale?catId=0&initiative_id=S...) is far better for a little bit more money. The specs are very good for the price. On the minus side, the oscilloscope doesn't have storage and the display is monochrome low resolution. However i have found it very convenient and useful in actual usage.
"All Sun" also has a whole range of handheld multi-functional scopes which seem pretty good.
No idea how good it is though.
