practically useless, after about 2 weeks from the first connection it started watering whenever it felt like it, with a little troubleshooting it tells you to add more nozzles because you have put too few and the machine gets confused.
After a month the contacts started to loosen and come out on their own (due to water pressure) resulting in pots flooding and others remaining unwatered.
Basically, when I needed it to leave for 3-4 days, I returned and found it broken and the plants unwatered.

I have now put tyreup on all the contacts one by one, hoping to save on extra expenses.

The kit is not complete or it is incorrect, the output from the programmer is threaded, a fitting is provided, but the reducer also has a fitting, so the connection between them cannot be made for the system to work. The components are of much lower quality than those sold separately. I have been using Gardena systems for several years, but practically anyone who buys this specific one cannot operate it.

I have it for about 2 months. The connection was not that simple. Also, the downside is that it doesn't have many adjustment options, let's say I have it every 12 hours but it opens for 3 minutes by force, resulting in water running from the pots. I dealt with this by observing and closing the faucet as needed.

Far away. First one broken. Changed from the store today. (I hope the new one opens as you program it and not as it wants whenever it wants)
Half clogged nozzles, bought new ones.
No extension hose connection parts were found even in authorized stores.
13mm hose, that's how you buy another one and start installation from scratch.
I hope the second one they gave me works.
