Nakkaa8 Inch Master Precision Level with Box Accuracy 0.0002"/10" for Checking the Straightness Parallelism The Surface of Machine Tools Equipment

To preface, I'm by no means a professional machinist. A hobbyist at best, and newish at that. I'm more of a hobbyist fabricator. This is plenty accurate and precise for me, exceedingly so for my needs. I got a precision ground to 0.0002" piece of granite as well and tested this with it. As long as I placed the level exactly in the same position (had to mark the location), I got the same reading every time. Also spinning the level 180 it was the same every time. It could even detect when I shifted my weight a little on the floor as I was on a wooden joist floor and the tiny compression from part of my weight moving registered significantly. Very happy with it.

I have a bench top lath and it is not super accurate so i don't need a professional level at 5X the cost. Once i figure out how sensitive it was to adjust i got it set up right. For me this is an acceptable trade off of cost verses ease of use. I may use it twice a year so it works for me.

Took me a little bit to figure it out and get it calibrated. . Very sensitive adjustments.

I've used plenty of cheaper tools and I know they often need to tweaking to be useful. I knew this wouldn't be as good as a Starrett since it's 1/3 of the price. But, at $56 I didn't think it would be completely useless. I thought wrong.Quality control was bad. The calibration screw had either some dried glue or plastic film stuck between it and the red cover plug. Once I got that cleaned out, the screw was misaligned with the plastic top of the tool, so I had to angle the screwdriver and be careful not to damage the screw. No way to move the plastic top.Then, I wasted probably 20 minutes trying to level this thing. You couldn't really make fine adjustments. A small move would send the bubble to the other side of the vial. Once I finally got it centered, if I picked it straight up and put it straight down, the bubble wouldn't return to the same place.$56 is a lot for a level-shaped paper weight. I guess I'm springing for the Starrett because this thing is useless.Don't waste your time or money.

Level is very accurate.
