This racket is aimed at advanced and pro male players who already have reliable technique and want a versatile, attack-leaning option. If you play an aggressive baseline or net game and need a head-presence that helps finish points, the Electra Stupa PRO ST3 suits those tendencies.

It’s not a beginner’s forgiving frame—the medium-hard feel and the EVA Hard core reward timing and clean contact. Players who prioritize outright power but still want workable control on volleys and defense will find this model familiar and effective.

The teardrop shape and medium-high balance bias the Siux Electra Stupa PRO ST3 toward power without making it a pure power-only weapon. That balance gives extra momentum on attacking shots—smashes and aggressive drives feel punchier than a mid-balanced control racket.

The firm EVA core and a 15K carbon face help transfer energy efficiently, so well-timed swings deliver strong ball exit and depth. The rough surface also assists spin generation, letting you add bite to heavy attacking shots and kick serves when required.

Despite its power bias, the Electra Stupa PRO ST3 remains reasonably manageable thanks to the medium-high rather than extreme head weight. With a weight range of 350–375 g, it’s stable on impact yet still allows for quick racket adjustments in fast exchanges for players used to mid-to-heavy frames.

Control comes from the combination of a stiffer face and the hybrid profile: volleys and block defenses feel steady, and the racket won’t twist excessively on off-center hits. Expect quicker-than-typical handling for its category, but allow for the additional inertia on very rapid directional changes.

The main face material is 15K carbon, which delivers a dense, responsive striking plane that balances stiffness and touch for powerful, controlled shots. The core is EVA Hard, a firmer rubber that gives pronounced ball exit and a crisp response.

The surface is rough, helping generate extra spin on serves and attacking strokes. Optional details from Siux’s Pro Series construction — including reinforced tubular materials and vibration damping elements — support durability and reduce harsh feedback on firm impacts.

On contact the Siux Electra Stupa PRO ST3 feels firm and direct. The medium-hard hardness and EVA Hard core produce a punchy, immediate response — you’ll notice strong feedback on well-struck balls and a quicker ball release compared with softer-core rackets.

The rough face translates well to controlled slices and topspin drives, so the racket feels particularly at home when you want to add aggression plus spin. At the net it feels stable and confident; in defense you’ll appreciate the predictability, though the firmer impact will be more noticeable than with softer, comfort-oriented models.

The firmer EVA core and medium-hard overall hardness mean the Electra Stupa PRO ST3 gives up some comfort in exchange for power and responsiveness. Players with elbow or wrist sensitivity may prefer a softer option.

At the heavier end of its 350–375 g range this racket adds momentum that helps offensive shots but slightly reduces extreme maneuverability. Finally, because it targets advanced technique, beginners will likely find its timing demands unforgiving until they develop consistent contact.
