Review on Suncala Stainless Steel Digital Protractor with Advanced Functionality by Alex Romero
not what i expected
as the old saying goes you get what you pay for. The locking knob must be sufficiently loosened, otherwise it will be tightened strongly when moving the metal blades and will be difficult to loosen. I had to use a thin file for the metal edges because they were sharp.
Pros
- constant test results
Cons
- boring packaging
