By far the most user-friendly menu in its category thanks to the large, easy-to-read screen which, combined with the rotary switch, makes programming incredibly easy.
(This is an area where the competition falls short, e.g., the Gardena Flex 01890-361 which I also have)
Purchased in May 2020 and has been working continuously since then.

By far the best machine I've ever had and the company is excellent in terms of reliability! I've had the machine for 6+ years without taking it out of the faucet, exposed to sun and rain 365 days a year, without any cover, and it still works like the first day, even in a network with a lot of salt!
As for the 1ZEHTMR, it's top-notch, impeccable quality, operation, and very easy to program!!!
The only downside is that for anyone who wants more than two waterings per day, it doesn't have the option!!

Awesome machine...permanently exposed to weather conditions. It doesn't understand anything!
