Quick Verdict

The Siux Electra Stupa Pro ST4 is a control-first teardrop racket built for advanced players who construct points rather than end them early. Its soft Black EVA core and 90/100 control rating reward precise, technical play. Biggest strength: pinpoint accuracy on demanding shots. Biggest weakness: limited raw pop on flat smashes.

Introduction

We expected a teardrop-shaped racket with a soft core to feel a bit sleepy at the net, the kind of frame that prioritizes touch over any real bite on a smash. The Siux Electra Stupa Pro ST4 flipped that assumption within the first few sessions. What it lacks in explosive power it makes up for with a level of directional precision that made us rethink what "control" actually means in a teardrop frame. Siux built this racket for the advanced player who values construction over chaos. The Mid balance keeps the weight distribution neutral rather than head-heavy, which shows up immediately in how the racket transitions between defense and attack. Paired with a Smooth surface and Soft hardness rating, this is clearly a frame designed around touch, spin application, and repeatable technique rather than brute force. We tested the Electra Stupa Pro ST4 across multiple sessions on court, rotating through both baseline defense drills and net-focused attacking sequences. What surprised us most was how the soft core managed to stay competitive on smash pace despite a modest 72/100 power rating on paper.

Performance on the Court

At the Back of the Court (Defense)

Chasing down a heavy smash near the back glass, the teardrop shape combined with the Mid balance gave us enough maneuverability to get the racket face square in time. It doesn't feel sluggish reacting to fast exchanges, which is often a concern with control-oriented frames.

On defensive lobs, the Soft core absorbed pace well, letting us guide the ball high and deep rather than fighting the frame. Low balls dug out near the glass came back with more placement than we expected from a racket in this hardness category.

At the Net (Volleys and Smashes)

Block volleys against aggressive drives felt stable rather than jarring, the Soft EVA core dampening shock on contact so the ball dropped softly into the opponent's court instead of flying long. Punch volleys carried enough pace to be genuinely threatening without needing an oversized swing.

Smashes are where the 72/100 power rating becomes noticeable. Flat, put-away smashes from a standing position lacked the last bit of explosive pop we'd want from a true attacking racket, though angled smashes into open space still found their mark consistently.

Spin and Control (Viboras & Bandejas)

The Smooth surface bit into the ball nicely on bandeja setups, letting us impart enough slice to keep the ball low and skidding after the bounce. On vibora attempts, the combination of Soft core and Smooth finish made it easier to brush up the back of the ball for extra rotation without overcooking the shot long.

This is where the 90/100 control rating becomes tangible rather than theoretical. Cross-court bandejas consistently landed within a tight margin, and that precision carried through multiple sessions of testing.

Pros and Cons

Pros

• The teardrop shape combined with Mid balance strikes a workable middle ground, giving advanced players enough maneuverability for quick net exchanges without sacrificing the plate size needed for control.
• Soft Black EVA core dampens shock effectively on block volleys against hard-hit balls, reducing arm fatigue over long matches or multiple sessions per week.
• Smooth surface finish enhances spin application on bandejas and viboras, giving shot-makers more tools to construct points rather than just react.
• Strong sweet spot rating of 83/100 means off-center contact on defensive lobs and rushed volleys still produces usable, controlled returns.
• Genuinely high control rating of 90/100 translates into repeatable accuracy on cross-court shots, a real asset for players who win points through placement.

Cons

• Power rating of 72/100 means players relying on flat, first-strike smashes from the back of the court will feel underpowered compared to stiffer, harder-core alternatives.
• The Soft hardness profile, while comfortable, isn't ideal for players who prefer a crisp, high-rebound feel off the strings on quick counter-attacks.
• Players transitioning from a diamond-shaped power racket may need an adjustment period, since this frame rewards technique over aggressive swinging.
• Those with a fast, powerful swing style may find the Mid balance underwhelming when trying to generate additional pace on smashes.

Construction and Materials

The Black EVA core is the backbone of this racket's identity, and it's a genuinely well-chosen foam for the control-oriented mission Siux set out to build. It flexes just enough on contact to soften harsh vibrations from smashes and drives, which matters over a long, competitive session.

The Smooth surface finish complements the core nicely, offering a tacky-enough contact point for generating slice and topspin without feeling rough or overly abrasive against the ball. Build quality at this price point feels notably above its current €149.95 tag, especially considering the original €324.95 price it was released at.

We didn't notice any flex inconsistencies or dead spots across the face during testing, which speaks well to the frame's construction. For the price we paid during testing, this level of material quality is a legitimate value proposition.

Who Is This Racket For?

This racket suits players comfortable on either side of the court, though it leans slightly more useful for the left-side player who relies on bandejas and lobs to reset points rather than the right-side smasher looking for outright power.

Playing style matters more than court position here. This is an all-court or defensive-minded player's racket, someone who builds points patiently and finishes with precision rather than overwhelming force.

Physically, the Soft core and Mid balance make this comfortable for players managing mild elbow or wrist sensitivity, since the shock absorption is noticeably gentler than stiffer, power-oriented frames. It suits players training or competing three or more times a week who need a racket that won't punish the arm over repeated sessions.

Players who should look elsewhere: the aggressive right-side smasher who lives for finishing points with flat, explosive smashes will find the power ceiling limiting. Beginners will also be underserved here, as the Advanced game-level rating reflects a frame that demands existing technique to unlock its control potential.

How It Compares

Within Siux's own lineup, the Electra Stupa Pro ST4 sits firmly in the control category, distinct from their more power-driven diamond frames. Against the broader budget teardrop market, it holds its own particularly well given its discounted price point relative to its original release cost.

Compared to the Wilson Blade Ls V3 Padel 2, the Stupa Pro ST4 offers a noticeably softer, more forgiving feel on off-center hits thanks to its higher sweet spot rating, though the Wilson tends to edge it out slightly in raw rebound off the strings.

Against the Varlion Black Carbon Varlion Cañon Diffuser 2023, the Siux comes out ahead on pure control and touch during bandeja and vibora setups, while the Varlion carries a slight advantage in punch volley pop at the net.

Frequently Asked Questions

Q: Is the Siux Electra Stupa Pro ST4 good for advanced players?

Yes, the Advanced game-level rating and 90/100 control score make it a strong fit for technically sound players who prioritize shot placement. It rewards clean technique on bandejas, viboras, and precise volleys rather than raw power.

Q: Who is the Siux Electra Stupa Pro ST4 actually best suited for?

It's best suited for an all-court or defensively-minded player who plays three or more times a week and values consistency over explosive power. Players managing mild arm or wrist sensitivity will also appreciate the Soft core's shock absorption during long rallies.

Q: How does the Siux Electra Stupa Pro ST4 compare to Wilson Blade Ls V3 Padel 2?

The Stupa Pro ST4 offers a larger, more forgiving sweet spot and a softer feel on defensive shots, while the Wilson leans slightly more toward rebound and pace off the strings. Players prioritizing touch and accuracy will likely prefer the Siux.

Q: Is the Siux Electra Stupa Pro ST4 still a good buy in 2026 considering its price and performance?

At its current discounted price of €149.95 down from €324.95, it remains a strong value pick for a control-focused advanced padel racket. The construction quality and performance ratings hold up well against newer releases in the same price bracket.

Final Verdict

The Siux Electra Stupa Pro ST4 earns a clear recommendation for advanced, control-oriented players who build points methodically rather than relying on overwhelming power. Its standout control rating of 90/100 isn't just a number on paper, it shows up consistently in cross-court bandejas and precise defensive resets during real match play.

The trade-off is honest and predictable: players chasing maximum smash power will find the 72/100 power rating limiting during genuine put-away opportunities. If your game depends on ending points with raw force, look elsewhere.

Buy it if you're an advanced, technical player who wins points through placement, spin, and patient construction. Skip it if your identity on court is built around explosive, flat smashes and raw power above all else.
