I've owned these speakers for ~4 years. Pretty good, well worth the price IMO. The only issue I've had is with the right speaker cable - due to the type of connector, it sticks out quite far from the sub and can be subject to strain. Mine is slightly damaged and requires wiggling around a bit every now and then to get it working, and since that cable is integrated with the speaker, it's not easily replaced.
So if anyone's thinking of getting them, just be mindful of that
