### 5/5 — work as expected

*2026-08-10*

I like the simplest way of managing my yard, the remote access really helped me as a "snow bird".

### 5/5 — Works Great

*2026-07-29*

Set up and connectivity worked flawlessly. Had to update the firmware and works and connects exactly as expected and advertised. 5 stars for making it simple. I understand it’s a newer app so I’m sure there are some bugs they are working w, but overall I’m very pleased with the system.

### 1/5 — Unusable

*2026-07-21*

Terrible system. It’s been unable to complete firmware update. Logged off, reboot controller, reset bridge, deleted & reinstalled the app. What a waste of time & money.

### 1/5 — Firmware update bad

*2026-03-06*

Did the firmware update and now my sprinkler doesn’t work! Why?

### 1/5 — App Button

*2025-05-18, version 1.0.55*

This app needs to be fixed as the button to run a station manually from an IPhone 15 is not easily reachable and    is just visible on the bottom of the screen

### 1/5 — Really buggy app and system

*2024-08-25*

The app and system are never in sync. I cannot run the system through my app. And I wasted money on buying the wifi bridge. I’m gonna soon replace it. Hunters are much better.

### 1/5 — App needs a serious update

*2024-08-19, version 1.0.55*

The app needs to be fixed. It keeps on hanging on the logo screen when I open it up. Even when I delete it and reinstall it, then it hangs on the login screen. I have only managed to get it working twice in the last week. This is extremely unstable software that needs to be tested before it is released to the public. I bought the system to control it remotely, but it has been very disappointing. If it is not fixed I will have to return it and buy another brand.
