I am amazed at how well the product is made, just magically!
A very helpful assistant has appeared. All lines are clear, at a distance they do not blur. There are many mounting methods. Even on the wall, even on the ceiling. I'm satisfied! Just like a store in general. Responsive and polite. (Master 360).
Pros
Small, light, already calibrated level. All declared characteristics are true.
Cons
Came a broken memory case. I contacted the store, they answered politely that they would send a new memory tomorrow.
