The Open-X is one of the cheapest open-top boxes in the catalog, and the owners who keep it mostly talk about the value: an open bowl like the Neakasa M1's for well under half the price, and one household with two automatic boxes has had no problems with the robot itself.
The owner reports that stand out are about the moving bowl. One owner heard their cat cry after it tried to jump in mid-cycle and caught a back paw while the bowl was still turning; the owner lifted the cat out and switched to manual mode. Another said the unit cycled onto their hand during cleaning. CATLINK's reply to the first owner was to keep curious cats away from scheduled cycles or use manual mode. Smaller complaints come from one owner each: the height, a front lip that traps old litter, phantom cat detection and smell. Owner reports are still few.
On a tight budget it works best with a calm cat and an owner who can schedule cycles for when the cat is out of the room. The manual describes anti-pinch protection, but a cat that runs to investigate every cycle is safer with the box in manual mode or scheduled around it.
