There are two Stiga Flow rackets: the basic Flow, and the Flow Spin. Both the photo of the packaging sleeve and the model number shown in the description are of the Flow Spin, yet the racket shipped is the basic Flow model. That was a disappointment, as there is a difference in the speed, spin and control ratings of the two models. This one is rated 5, 5, and 9, respectively.
Since I bought this on a lark, just to see what an outdoor racket was like and because I liked its look, I won't go to the hassle of returning it, but I do think the information provided for this item is deceptive, describing as it does a different racket.
I have used it a few times now and am still getting used to it. It is heavier than my indoor rackets, and the extra weight seems to be in the handle. (A fellow player uses the Cornilleau outdoor racket, and his is significantly lighter.) There is no sponge under the "rubber", so contact with the ball produces a clicking sound -- as if the ball were broken.
This racket is not approved for tournament use, but it is fine for recreational play. The high "control" rating would make it a possible choice for beginning players. There really is no reason to buy an outdoor racket, however, unless you are storing it outside, or using it in inclement weather. Or you just happen to like the look of it, which is my reason for trying it.
Overall it is average, but I rated it "poor' in meeting expectations because it is not the racket identified in the photo/description. I was expecting the Spin model described, and I didn't get it.
