### 1/5 — Doesn’t work

*2023-04-11*

Does not work.

### 5/5 — Level protractor plumb tool

*2022-11-12*

Excellent! Well worth the 99 cents. The level is accurate within one tenth of one degree! If you need to be that accurate, consider the buttons if using the side of your phone. 

I have not put the other tools into actual use yet, but they work beautifully! For the protractor, drag one of the pointers in the middle to the exact angle you need. The plumb represents a 3 dimensional view of straight up and down nicely with very accurate number measurements as well.

### 2/5 — Very disappointed!!
