Question:

What are the door closers cheap and durable?

At least 2 years old, because I am doing the project, you can need a large number of purchases. Others say the Internet is cheaper, but not kind, afraid of poor quality. We recommend to me.

Answer:

And then there is a regular test report price between 30-70, for example, GMT and then up is the international brand, and Gezer estimated that you will not consider expensive but really stable, which is not the same door
The key is the frequency of use of the janitor
