Andro Rasanter R37 Review: Soft 37-Degree Spin and Control Rubber

By UltraSpin · 2026-07-13 · rubber

Released as part of Andro’s Rasanter R series alongside the R42, R45, R47, R48, R50 and R53, the Rasanter R37 sits at the soft end of the lineup with a 37 degree ESN sponge, the softest hardness rating in the whole family. Reviewers across Revspin, Megaspin, Reddit and TableTennisDaily treat it primarily as a control and spin rubber rather than a speed rubber.

Performance

On paper the R37 uses a 37 degree ESN sponge, which one Megaspin reviewer measured independently at 32 degrees on the Shore A scale, mounted under a thin, very grippy topsheet with short pips and a slight natural tack. Andro’s own marketing copy on Megaspin lists in-house indices of Speed 113, Spin 126 and Control 91, and notes the rubber is built for mid to advanced players who prefer ‘the soft 37 degree sponge for allowing precise active topspin play and control.’ Revspin’s community of 44 raters backs this up with an Overall score of 9.2 out of 10, driven by Control 9.4, Consistency 9.1 and Spin 9.1, against a comparatively modest Speed of 8.7. Where reviewers diverge is on raw pace. TableTennisDaily’s own rating puts Speed and Spin at only 6.5 out of 10 each, and its lone written review calls the R37 ‘the softest Rasanter among the 6 variants and also the slowest,’ adding it is ‘slower than the Rasant Beat and also has less spin’ even though the Rasant Beat was the softer of the two rubbers. On Reddit, players comparing hardness numbers note the R37’s 37 degree rating sits well below the Rasanter R42 and Xiom Vega Europe (42.5 degrees), which is why one coach quoted in a Reddit thread reportedly recommends ‘R37 BH and R42 FH for beginners.’ Multiple Megaspin reviewers describe the sponge as bottoming out under full-power hits away from the table, while staying composed at mid distance and mid power. The long dwell time is the throughline across every source: Revspin’s dbeff writes that ‘the spin is also good because of the dwell time due the soft sponge,’ Kaishi lists ‘dwell time’ as a top reason to run it on backhand, and a Megaspin buyer measured a mounted 2.3mm sheet at 44 grams on a 90-gram blade, confirming the rubber’s reputation as a light setup piece. That combination of soft sponge, long ball contact and grippy topsheet is what lets slower swings still produce heavy loop spin, which is also why almost every reviewer steers the R37 toward backhand or mid-distance forehand loop play rather than close-to-the-table power hitting.

What Reviewers Agree (and Disagree) On

All four sources agree the R37 is the softest and most control-oriented rubber in the Rasanter R line, with outstanding dwell time and spin at moderate swing speed. They disagree on how it stacks up against speed: Revspin’s community rates it a fast-feeling 8.7/10 for speed, while TableTennisDaily’s stats and several Megaspin reviewers describe it as clearly the slowest Rasanter, one that bottoms out on hard, full-power hits away from the table.

Who Should Buy It

Buy the R37 if you are a control or all-round player who relies on spin and touch rather than raw power, especially for backhand or mid-distance forehand loops, as recommended repeatedly across Revspin and Megaspin reviews. Skip it if you are a heavy forehand smasher or third-ball attacker looking for maximum speed, since one Megaspin reviewer notes it is ‘not an ideal rubber for a 3rd ball attack’ and TableTennisDaily rates its speed at just 6.5 out of 10.

FAQ

What sponge hardness does the Andro Rasanter R37 use?

The R37 uses a 37 degree ESN sponge, the softest in Andro’s Rasanter R lineup (R37, R42, R45, R47, R48, R50, R53); one Megaspin reviewer measured a sample at 32 degrees on the Shore A scale.

Is the Rasanter R37 better for forehand or backhand?

Most reviewers favor it on backhand, including Revspin’s Kaishi who calls it ‘the greatest backhand rubber right now,’ and the Megaspin review that recommends it ‘as a BH rubber to almost all control players,’ though some Reddit users also run it on forehand in beginner setups.

How does the R37 compare to the Rasanter R42?

The R42 uses a firmer sponge and plays faster with less dwell time. A Reddit thread notes a coach recommending R37 on backhand and R42 on forehand for beginners, pairing the softer R37 for control with the firmer R42 for extra pace.

Is the Rasanter R37 durable?

Revspin users rate its durability 7.8 out of 10, describing it as lasting longer than average for a soft ESN sponge, and TableTennisDaily lists a similar 8.1 out of 10 durability score.

Does the Rasanter R37 suit third-ball attacks or forehand smashing?

Not really. A Megaspin reviewer states it is ‘not an ideal rubber for a 3rd ball attack,’ and TableTennisDaily’s user stats rate its speed at only 6.5 out of 10, so heavy forehand hitters typically prefer a firmer Rasanter like the R47 or R50.
