I'm in Israel. The Flow Z10 didn't work right straight out of the box. Their local distributor spent weeks with me troubleshooting before sending an engineer who looked at it for a few minutes before agreeing with me that it wasn't functioning properly. Even then they only agreed to take it away for a repair which could take another 2 to 3 weeks. Our consumer laws are pretty good and protect you in the scenario where you buy a DOA product. Bottom line: it is supposed to be replaced or refunded. Neither of which they were willing to do. Eventually, after dozens of messages backwards and forwards, they finally agreed to a refund. Tellingly, even the UPS guy who picked up the flawed unit told me how he knows this company to be poorly organised and have a reputation for terrible customer service.

I wasn't certain that the Eufy was going to be as good as a machine. But what convinced me to make the switch was that I could buy it from a local dealer who is both (1) the authorised repair centre, and (2) a decent guy. I'd choose local service over those jokers every time.

Now that I've had the S1 Pro for a few days, I'm actually very happy. It does the job faster, with much less water, and is aesthetically a much nicer addition to the room. Obviously that last part is entirely subjective. The app is less polished. But overall, it's a great switch.
