The AWS market is now crowded with so many Chinese instruments that are cheaper than the ones from established players. If their build quality is good, then they will give a tough competition to the likes of Davis, Acurite, Ambient, La Crosse, etc. I think Davis will suffer the most, since it is the most expensive of the lot and you need the outdoor sensor, display unit and a data logger to transmit data to outside servers or the weather link system which seems transmit data to other servers at 15 minutes interval (the free version).
