For the job I need it for (car washing - seats, carpets), it's perfect. The release valve works great, it also holds pressure very well. Indeed, the front adjustment is not very precise, but for the job I do, it's enough the way it works.
For its price, it's superb, I should have bought a second one as a more expensive spray bottle from the paint shop broke after 2 uses.

Unfortunately, I cannot do my job so economically...
The spray adjustment is not very clear, and with just half a turn on the screw, it leaks and falls off... it's approximate.
The absolute failure was with the release valve. It simply doesn't work. The only way to release the pressure is to completely unscrew the cap.
Overall, it would have been better if I had paid for something more high-quality from the beginning.

Quality plastic material construction with good hydraulic pressure from top to bottom and at the front edge of the nozzle for liquid discharge.

For the price, it's fine. For quality, it's fine. The function is perfect. There is nothing negative as far as I'm concerned.

Satisfactory quality for the price, however, the nozzle is not adjustable with such detail to achieve a 'cloud' effect, so if you just want to wet the soil of newly bloomed seedlings, you don't drown them with water.
