Unfortunately, both the small and the large one have developed problems.
I used both of them very little while keeping them stored in the warehouse, the small one got a hole and I made a makeshift fix to use it for spraying and it was leaking water at the joint where the nozzle connects to the tube, then it would throw it off completely causing the chemical to spill, luckily I was wearing my gloves. I bought them for something more 'quality' but unfortunately, it was a dud

Although I haven't had it for long, I used it to spray antifungal in areas that I couldn't reach due to lack of a ladder. It helped me a lot. I didn't see any leaks in the connections and it has good pressure.

It lasted only 2 years, with spraying around the house twice a year for cockroaches, mosquitoes, etc. And then it broke... I patched the hole by melting plastic, and it worked one more time. Then I threw it away.

I have bought it to spray insecticide for cockroaches in hard-to-reach areas (e.g. in the corner under the kitchen cabinets from the side where the pots go, etc.) since it required 30 centimeters to reach and seal the gap with a stick by putting it on a spatula, and the sprayer saved me. Since I started using it and spraying insecticide at the source, there are no bugs inside the house.
Once a month, I apply one or two sprays in that specific area, depending on the season and the number of bugs.

Good product for its price. Large capacity, nice spraying. I have used it several times with cleaners, not chemicals of course. The only negative was that the rubber in the air isolation chamber was burnt. But they provided a replacement, so now it works perfectly.

Very good build quality! It does its job and its price is right (quality-price ratio). I highly recommend it!

Waste of money. After 4 months of household use, not daily, and without any chemicals, the container got punctured after pumping for flower spraying. The negatives are the fake plastic and the lack of a release valve. The only positive thing and the one star is that it sprayed nicely, nothing else. I wouldn't buy it again. It's the third cheap sprayer I've bought and it's garbage. If you want a sprayer, only trust Gardena. You get what you pay for in the end.

Good build quality. Satisfactory pressure. The brass nozzle is a plus. The misting is excellent and it drips very little.

I bought it to rinse off the dust from road works, dirt, etc. on my bike and car, unfortunately it is not suitable for this job. Of course, I didn't expect it to have enough pressure to wash off dirt or stains, but not even the dust? The worst part is that when I unscrew the blue ring, the top part comes off and leaves the black cylinder inside, which is for air. Then I have to unscrew that as well to fill it with water, and my hands get dirty from the "grease" that the factory has put on it.

There will definitely be better ones, but I got it for €3.15 and only because of its price, I give it 5 stars. It does its job as expected. Very satisfied.

Unfortunately, I was unable to use it because the instructions it had were inadequate. So, I gave it to someone who has a vacation home and estate to use it in the best way possible.

Two uses. Very decent and effective. Maybe for tall people like me, it would be better to have a longer nozzle.

For its category and price, the best! It also comes with a small plastic dosimeter.
