Excellent innovative idea my only problem was that the rotating angle arm locking mechanism did not work very well

I also think the bubble should touch the lines not somewhere in between

The only reason i gave 4 stars is that when you want to hold it at the angle so you tighten the screwnut thing it isnt tight enough and can still loosen too easily

I have to agree with other purchasers regarding the locking mechanism

Overall i am very pleased with this item and only deducted 1 star for the locking mechanism would have only deducted 0

A digital bevel gauge would be better for this

There is an amount of ‘stiction’ but this was not enough to hold the arms reliably but enough to make setting exact angles tricky

I wonder whether there is an o ring or washer missing from under the knob
