Laser Edge Automatic Leveler

Pros: I don't know what to put in this section ('pros') because this thing doesn't have any particular features. It just works. Using a good old bubble in the leveler you put it right, then press the button and get a straight red line. Now you can align whatever you're hanging to be perfectly parallel / perpendicular to the ground.

Cons: Unless you buy a reusable adhesive, you will have to use pins to attach it to the wall, or your wife/whoever to keep it there while you're aligning the object you're hanging with the red line. I don't like the idea of using pins because they leave marks on the wall, and I didn't yet have a chance to run across a reusable adhesive. The manual says, this adhesive is available at most major retailers - obviously not in my country.

Other: Works as advertised. The line is highly visible. No problems so far. Very useful and very much affordable. Highly recommended.

Pros: é realmente funcional, da para fazer uma média com a peaozada, é muito prático e dá produtividade na obra, mas para trabalhos que exijam precisão é melhor usar o método convencional ou um nível de melhor qualidade...

Cons: a qualidade é meio duvidosa, os prendedores são ridiculos, melhor se nem viessem com o aparelho...

Other: ...[ escrever 500 caracteres sobre um nivel é muito dificil ] ... vamos enrolando, enrolando, enrolando, enrolando enrolando, enrolando, enrolando, enrolando enrolando, enrolando, enrolando, enrolando enrolando, enrolando, enrolando, enrolando

Pros: Very bad. Poor construction, not precise, difficult to use because it is not fixed. I can´t see anything good.
Muito ruim. Péssima construçaõ, difícl de usar, Não mtem como fixar.

Cons: Everything. How can I use a level without any precision?.
Tudo de ruim. Para que serve um nível torto?

Other: Don´t buy it.
Compre para guardar na gaveta e nunca usar!
