This is the 2017 model, SM-R324, designed to be compatible with the Samsung Galaxy S8, S8+, S7, S7 edge, Note5, S6 edge+, S6 and S6 edge. Compatibility details here: http://www.samsung.com/hk_en/supp...aq/1134413
It comes with a controller, and is supposed to be a big upgrade over the 2016 model.
This is NOT the newest model, SM-R325, a minor upgrade that added compatibility with the Note 8. I've read on various forums that you can actually fit the Note 8 into the older SM-R324, but it might be tight and I can't recommend it. Do your own research.
