I have this model, I have yet to use it but I can tell you it arrived in good working condition and in a timely matter. Make sure you turn the VEG button on FIRST even if your gonna be using the bloom. ( meaning, both switches are one for flowering).
I'm just mentioning the above because mine shipped without instructions, but I was already aware of having to do this due to the idiocy of a reviewer who decided not to read instructions (bloom alone damages light, atleast it used to.)
If you would like to see how these lights work, some users such as BID and Buckshot are reviewing them. Their grows convinced me to purchase the light in the first place. Check those grows out to answer your performance questions!
