Andro GTT 40 – a versatile table tennis rubber designed for players seeking high control, spin, and comfort.
With a soft 40° TENSOR technology sponge, a modern grippy top sheet made of 100% natural rubber, and pips optimized for spin-focused strokes, GTT 40 provides an excellent balance of speed, spin, and control. Made in Germany and ITTF-approved, this rubber is ideal for beginners, young players learning technique, and experienced players looking for maximum comfort and reliability for all-round strokes close to the table or at mid-distance.

Andro GTT 40 stands out with a construction that emphasizes control, feel, and spin, adapted for modern table tennis with 40+ plastic balls:

• Soft sponge (40°): Soft (close to 37–40° on the ESN scale), made with 4th generation TENSOR technology, the sponge delivers a gentle "catapult" effect, excellent ball contact, and a high forgiveness margin. Small pores allow precise ball feel, compensate for slight stroke inaccuracies, and facilitate learning technique. Compared to Andro Hexer Powersponge (40°), GTT 40 has a slightly reduced catapult effect, focusing on control rather than speed.

• Grippy top sheet: Made from 100% natural rubber, the modern top sheet is highly grippy (not tacky), designed for a variety of spin strokes. It enables strong spin generation in topspin strokes, serves, and counterattacks, creating high and variable trajectories. Compared to Andro GOOD, the GTT 40 top sheet is more modern, offering better grip with plastic balls and higher spin potential.

• Pips: The rubber’s pips are medium-width, densely arranged, optimized for spin-oriented play. Their geometry ensures long ball contact, clear shot feedback, and stability that allows precise control of trajectory and spin. Compared to Andro Hexer Grip SFX, GTT 40’s pips are less aggressive, focusing on control and learning technique rather than maximum spin.

• Tuned TENSOR effect: Andro GTT 40 uses a precisely tuned TENSOR technology that provides a mild speed boost while maintaining high control. Unlike more aggressive TENSOR rubbers such as Andro Rasanter, GTT 40 emphasizes feel and stability, making it suitable for beginners and players who value comfort.

The rubber is available in sponge thicknesses of 1.6 mm, 1.8 mm, 2.0 mm, and Max (2.3 mm):
1.6 mm and 1.8 mm are suited for maximum control and technique training, 2.0 mm for all-round strokes, and Max for slightly more aggressive topspins. The rubber is lightweight (uncut ~60 g, cut ~40–42 g), comparable to Tibhar Aurus Soft or Donic Acuda S3. Colors – red and black – meet ITTF standards.

Andro GTT 40 features technical specifications tailored for beginners and control-focused players:

• Speed: 96/100. This is a slower rubber, suitable for topspin strokes, flat hits (drives), and short strokes (flick, push). Compared to Andro GOOD (speed 110/100), GTT 40 is slower, offering more control and feel, ideal for learning technique.

• Spin: 101/100. The rubber generates strong spin, especially in looping topspins, serves, and attacking against backspin. Compared to Andro Hexer Duro (spin 107/100), spin is slightly lower but compensated by higher control and easier handling.

• Control: 92/100. The control level is high, especially in blocking, short strokes, and slow topspins. Compared to Andro Hexer Powersponge (control 100/100), GTT 40’s control is slightly lower, but the modern TENSOR technology adds dynamism.

Trajectory: High, facilitating topspin strokes and attacks against backspin. The trajectory is similar to Tibhar Aurus Soft, but GTT 40 offers a softer feel and greater forgiveness. Users emphasize the rubber’s “comfort” and “stability,” especially when learning topspin technique.

Andro GTT 40 is a soft rubber, making it well-suited for various blades:

• Andro Novacell ALL: Balances speed and control, suitable for beginners and young players.

• Butterfly Primorac OFF-: Provides extra speed for topspin strokes while maintaining control.

• Yasaka Sweden Extra: Enhances spin, especially in looping play.

• DHS Hurricane 301: Adds stability, good for wood blade enthusiasts.

The rubber is also compatible with harder blades, such as Butterfly Korbel, as the soft sponge and tuned TENSOR effect compensate for the blade's stiffness. Users recommend using GTT 40 on both sides (forehand and backhand) with 1.6 mm or 1.8 mm sponge for beginners, or 2.0 mm for intermediate players seeking more versatility. The rubber is optimized for plastic balls, as the top sheet effectively generates spin and control.

Andro GTT 40 is designed for players who emphasize control, spin, and comfort:

• Beginners aiming to improve technique, as high control and forgiveness make learning strokes easier.

• Young players starting out in table tennis, thanks to easy handling and modern TENSOR technology.

• Intermediate players looking for a comfortable rubber for all-round strokes.

• Experienced players wanting a reliable rubber for the backhand side or for a controlled game.

• Play close to the table: Short strokes (flick, push), blocks, slow topspins.

• Mid-distance: Looping topspins and controlled counterattacks.

The rubber is effective in serves (8.5/10) due to strong spin, and in blocking (9.0/10) it offers stability and precision. Against backspin attacks (8.7/10), the rubber makes it easy to lift the ball with a high trajectory. Compared to Andro GOOD, GTT 40 is slower but more modern, with a TENSOR effect suitable for technique learning and variable play. Users praise the rubber’s “comfort” and “confidence-inspiring feel,” though note it may be too slow for aggressive shots from far away.

Andro GTT 40 stands out as a rubber focused on control and comfort:

• Slower speed (96/100), suitable for technique learning and controlled shots.

• Strong spin (101/100), effective in looping and serves.

• High control (92/100), ensuring stability and forgiveness.

• Soft TENSOR sponge: Provides a gentle “catapult” effect and feel.

• German quality: ITTF-approved, crafted with Andro's precise craftsmanship.

Compared to Tibhar Aurus Soft, GTT 40 is slower but more controlled, with a gentler TENSOR effect. Compared to Donic Acuda S3, it offers a similar feel but is easier to handle and more durable (3–5 months of intensive use). Users highlight the rubber’s “versatility” and “comfort,” especially for beginners.

Andro GTT 40 is ITTF-approved and suitable for competition at all levels, especially for beginners and young players. Its high control and spin allow effective rally management, especially in blocks, short strokes, and slow topspins. The natural rubber top sheet enhances serve quality, and the soft sponge ensures stability in reactive situations. The rubber is a popular choice among young players and technique-learning enthusiasts, proving itself as a trusted partner for developing table tennis fundamentals.
