A low score does not mean the racquet is bad and does not reflect its technical quality: often it is just missing data or reviews. The specs combine several sources and may have discrepancies: check the manufacturer's website and the store where you buy. ## Buyer reviews Average of the ratings given at each store, weighted by how many reviews each one has.
