Siux Electra Pro ST4 2025 Reviews

Unperforated center on the 15K carbon face gives the update a wider sweet spot and a crisp, dry feel on clean contact. At 361g with a 26.5cm balance, it's noticeably easier to defend with than the old ST3 and gives you more bounce on lobs and three-point smashes. The heavy sandy grit also bites great when you're slicing volleys at medium pace. That extra rebound comes with a catch, though, when the rally speeds up. If you don't get set early and pull the tip down on fast víboras or aggressive volleys, the ball can easily float into the back glass.

Got no center holes on the ST4 for a bigger, firmer sweet spot, and the smoother butt cap won't dig into your palm on low-grip blocks. It's a super complete all-rounder, though the core absorbs some pace on flat smashes.

Got a 26cm balance on a hybrid frame that handles great on reflex volleys and keeps your víboras skidding low and deep. It's surprisingly punchy when you commit to your swing, though you won't get free head-heavy kick on smashes. You'll want to rip off the weird, slippery factory grip right away, and the odd impact sound takes some getting used to.

That sandpaper-like grit on the 15K carbon face is wild, biting the ball hard on topspin smashes and whipped overheads. Its hardness sits right between the softer ST2 and the stiffer ST3, while the long handle gives you great leverage at the net. Still, it doesn't feel as dry as the ST3, and the sweet spot takes a few sessions to really feel.

A former tennis player recently switched to the Electra ST4 Pro and is very happy: big sweet spot, easy to handle, with a rough sandpaper-like surface.

Moved from a cheap AliExpress racket to the Electra ST4 and found it amazing: handles well at 355 g with overgrip and suits a spin-and-slice game.
