Paid $15 with the $5 coupon for the microscope. For soldering some very small micro boards. Now I have not actually used it yet, as far a the app goes, it worked just fine. Turned on the WiFi and started app up and it worked.
The scope is too much magnification for me but not the apps fault, it tries, you can flip in case its mirrored, flip the image, rotate, so for what it is, its OK.
It should get 3 stars, but considering everyone else’s issues, I feel like this worked right away, so 4 stars.
