I was not satisfied at all.
It does not maintain high pressure inside, as the valve opens and the pressure is lost.
The water pump hose was damaged and I had to cut it, resulting in a loss of length.
When you press the lever to spray, it releases a lot of water from the top, causing it to be lost from spraying and everything gets wet.

On the second use, it opened at the bottom of the container where the plastic is glued together.

Do not use it for spraying indoor air conditioners. All the liquid will run on your hands when you press the spray button (especially on my air conditioner, which does not fully open the lid due to incorrect placement) and I had to tilt it slightly. Choose the one with the long nozzle in front that is actually for air conditioners. Use it for spraying plants. The nozzle sprays in a circular pattern, meaning that if you imprint the liquid on paper, it will form a circle design.
