From the reviews on Amazon, the story seems to be that mostly they work at first; but if you look at the poor reviews they are mostly from people who waited a few weeks to review and they all say that they leak :(
other issues seem to be that, unlike normal hose, a split cannot be cut out and repaired, and often existing connectors don’t fit although they are described as standard. For me, a better option has been an auto watering system (micro drippers and leaky pipe) I connect the hose to one end of the system as needed.
