From a brief market research I did for an irrigation programmer, I don't think there is any other than the Eurodrip 101068151 with a more easy, friendly, understandable, affordable, and intuitive menu and programming. Just look at its nice, large, and readable LCD screen, which provides all the necessary information at a glance. That's why I chose it. You don't even need the manual, you will never need it! As for its construction, it looks high-quality. Time will tell. Hopefully, it will withstand the test of time and operate reliably. I will come back regularly.
One great advantage (that not many other programmers have) is that you can adjust the watering duration from 1 second (while most start from 1 minute), which makes it ideal for balcony plants that require a little watering multiple times. The only possible drawback is that it has only one program (which, however, has plenty of options). In other words, you can't program it to water every day at 8:00 and every Monday at 21:00. You would need a programmer with 2 programs for that.
I purchased the Eurodrip 101068151 from a large store in Athens, while in European branches (sites) of a large and well-known market mall abroad, the same (at least it appears so) programmer is quite popular, with many purchases and good reviews, circulating under different names in various Chinese brands such as: CROSOFMI, Kazeila, Johgee, HWGING, NINAINAI, Hugyue, Jtoony, Cresman, SOGUYI, etc. In fact, in these brands and with a relatively small price difference, there is also a next model that has 3 or 6 programs and an integrated rain sensor.
The installation was done on 25/06/2022 and it was very simple and easy. To avoid the hassle of screwing and unscrewing it and to avoid having to use Teflon tape or new washers, etc., for sealing, I recommend using an adapter like this one (https://www.gardena.com/int/products/watering/hose-fittings/threaded-hose-connector-26-5-mm-g-3-4/900874401/) at the water inlet to the device, so that it can be attached to the faucet supply with a connector like this one (https://www.gardena.com/int/products/watering/hose-fittings/tap-connector/970521701/). Something similar can be done at the water outlet from the device to the watering hose, so that the programmer can be easily attached and detached each time, quickly and safely. This way, you avoid inconvenience and any potential water leaks at the connections each time.
UPDATE 17.07.2022: The programmer waters 10 large balcony plants daily for 1 minute. So far, it works flawlessly with the start and stop of watering. The battery status indicator on the screen has a total of 4 bars. Within 3 weeks, one bar dropped from the battery indicator (with 2x1.5V Toshiba High Power Alkaline batteries).
UPDATE 25/08/2022: The programmer continues to work flawlessly. From 5/8 to 25/8, it operated twice a day, watering for 1 minute in the morning and 1 minute in the evening, watering the 10 large balcony plants. With the same batteries, the battery status indicator on the screen remains at 3 bars (out of 4 total). Therefore, the programmer's consumption is considered highly satisfactory for two months of daily operation.
P.S.: I previously had two first-generation Florabest programmers. The first one broke within a month and would shut off on its own whenever it wanted without watering. It was replaced under warranty, but it broke again within six months. The service told me that it has a faulty solenoid valve from the factory. The second Florabest flooded the plants and the balcony within two months, luckily we were there. I didn't even bother with the warranty. I threw both of them away. Let's not even talk about the programming of the first generation Florabest, which I consider to be the "most difficult" in the world! Maybe the second generation Florabest will be more reliable and have easier programming.
