Cheap paddle for normal use at sea; but I also recommend, as my earlier commentators to have twisted the paddle rods because everything is made of plastic and is durably not necessarily in constant rotation. Rowing machine please check to see if the rudder blades are well fixed. Mir is in fact a leaf flute gone, because it has turned out of the thread during the rowing. But nothing happens, the leaf floated quietly on the water surface ...
For so little money you can not expect much quality you, but they serve their purpose in a Einsitzerschlauchboot wholeheartedly. I was at least good progress, the rods do not bend, and had my fun with it!
