It break with conventions, use the strengths of the andro ENERGY CELL technology: which gives more power with hard topspins and game openings on backspin, high dynamics and longer ball contact time to be felt.

The andro ENERGY CELL sponge has highly elastic cell structure which ensures an extremely dynamic energy transfer, especially for fast and hard topspins.

The 53 ° sponge provides immediate feedback on ideal ball contact. Its surprising how soft 53 ° can feel like.

The R rubber surface for maximum rotation gains additively more impact through the ENERGY CELL sponge.
