I don't have any experience with this particular model, but in general, I don't see anything wrong with most generic brand Chinese incubators. In my experience they usually work well. The thing is, that they are (more often than not) made with cheap and not very durable parts that can break down or malfunction. If you can fix it quickly you might still save the hatch, otherwise... better luck next time.
I'm not saying all Chinese incubators break down, in fact most work great. But still, it can sometimes feel a lot like a lottery when purchasing a new incubator.
