Tightness 1 review

Level efficiency, RAS. He does this job. The range of such a system varies depending on the terrain and location (the earth's properties and possible hidden obstacles can increase or decrease the propagation of waves).

However, I did not keep long. It took water quickly enough at the plastic part of the tube which is used for LED lighting. Maybe I pushed too; Yet I had been careful to leave a little height precisely to avoid this.

I would favor the version without LED.
