For an affordable price, it does a very good job! It is powerful with a time of relatively rapid recycling. It is compatible Canon and Nikon. Personally, I tested with a Nikon D800 + SB700 1 multiple flash. It is nickel, it works perfectly with the Nikon system. I can assign a group and control it in manual mode with a power setting on several levels. It is quite large and quite heavy (more than my SB700) but that does not bother me. The construction is rather good (check with time). For cons, the manual is in English (not French) but it is clear and easy to understand. I highly recommend it!
