Absolutely Great

Nice compact unit, Sprays a nice fine mist that gets every corner of the aquarium, no complaints here. Previously ordered another version atomiser from these guys here, and it turned up broken, there were very helpful and a pleasure to deal with with a credit towards this one, great customer service.
