32*7MM Mini Portátil Nível de Bolha Inclinação Instrumento de Medição Ferramenta Grau Marcado Conta Horizontal de Plástico

It is useless, because it is much too small, so it has no stability in the plane and, for example, placing it 4 times in the same place, it showed 4 different inclinations. After the photo, I thought it was 8-10 cm in diameter, but in reality it is a joke.

Very clean processed. When tilted, always displays the bubble to the side where the tilt is. Which is supposed to be the case, but unfortunately is not the case with many other dragonflies. Therefore also useful.

Exactly as ordered and expected. Its small size makes it very easy to use without having to take out bulky spirit levels. Very practical and can be stored anywhere.

Everything top for redeeming points at Joom a great bonus. Quite useful from time to time and works perfectly. For example, checking with the customer whether the naked eye is right or not. Thanks very much!
