"The item's not bad ... for the money does exactly as you want/expect it too ...
Only real downside is the build quality, you have to be a little nice to it, otherwise you twist the screw too far and it falls apart in your hands ... luckily its a simple bit of kit and you get put it back together in no time ..."
"Sadly, I have to agree with the other reviewers who have pointed out how badly this is designed.
In almost all circumstances, the rounded black plastic end of the tool interferes with your attempt to determine an angle. It IS usable for certain measurements, but that's just not good enough - I want one tool for the job, not this one and a tool for the things this can't do.
It's well built otherwise - plastic is solid, nut is sturdy enough, blade is a good bit of steel, built in spirit level is handy... But the above point kills any hope of a recommendation."
"Got this for a one off job, Wish I'd read earlier reviews on this as had to take it back due to it's inability to measure internal angles accurately. Poor Build Quality. Was unable to use, and ended up folding a piece of card for the angle instead."
"I ended up taking this back. The rounded plastic end sticks out further than the metal part, so you can't accurately use this to measure the inside angle between two pieces of wood (for example, a stair's stringer and newel).
I've since used a well designed one which did this without problem."
