Siux Electra Pro ST4 2025 Reviews

Five months in: amazing power yet very maneuverable in defence with a good sweet spot, and a dry touch with no trampoline effect.

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.

Preferred it to the AT10 12K 2025 in every area: lighter, bigger sweet spot, great volleys and overheads.

Used the ST4 until it cracked: versatile with a good mix of control and power and a decent sweet spot; the trampoline effect gives free power but takes a little from control.

Testing the Siux ST4 Pro against the Babolat Counter Viper 2025, they find the ST4 more helpful: plenty of power, an easier x3, a huge sweet spot, comfortable all match and better lobs.

A right-side player who gets most smashes back into their own court with it; loves it.

Calls the ST4 Pro their best racket ever: some trampoline effect but crazy power, light and easy to manoeuvre.

Bought the Diablo but swapped it for the Electra ST4 Pro; loves its control and power.

Tried it once and loved it as a well-rounded racket with good power.

Paint chips easily, but it's structurally solid; their smash improved with it compared with the Diablo 3.
