The Nike SQ Sumo irons are meant to be part of Nike's 'square' family of clubs and the clunky design of the head certainly gives that impression, although in a positive way.
Each club has a thick top edge and a slight offset which helps give you lots of confidence without looking like an out and out game improvement iron. Right through the set the Nike SQ Sumo irons were effortless to hit and the forgiveness was excellent.
The ball trajectory was maybe a little higher than the Nike Slingshot 4D irons but the feel was definitely as good. The shorter irons seem to have a little more bounce on the soles than usual, so if you play links courses a lot then these probably aren't for you.
Overall a very good set for mid to high handicappers.
