Product is good and sturdy. Heavy duty feel

This level will vastly improve the accuracy of whatever you are trying to build or install. I used it to build an airplane an it was awesomely easy to get it perfect with this level.

I bought two of these levels, so I could compare the reading at two different places on an object and make the angles the same. I stacked both levels on top of each other, one read 0.00, the other read 0.09. I looked at the instructions included, and they did have a calibrate function. This does not work, and then I looked at the website, downloaded the current instructions, and found they had omitted any type of calibrate instructions. So, I think I will have to split the difference on readings, or ignore the Hundreth's digit when using. just wanted to let folks know , so they don't expect to be able to make two read the same thing.

Only thing I'd change is adding a magnetic to it.

I used this mainly to measure pipe sloped in a trench. I could reach down, set the level, lock the read and voila. I could make sure my pipe was sloped at a minimum of 1%. Came in very handy and saved me a ton of effort to measure slope. Loved it! It got dirty, muddy and still worked just fine. Will be a handy tool for many projects.
