Butterfly Rozena Review: Tenergy Spring Sponge, Built for Control

By UltraSpin · 2026-06-06 · rubber

Released in 2017, the Butterfly Rozena quickly became one of the most popular rubbers in the game by answering a simple question: what if you took Butterfly’s Spring Sponge and made it more forgiving? It is pitched squarely at developing offensive players, and it leans into control rather than chasing the spin and speed crowns of the Tenergy line.

Performance

Control is the headline, and reviewers are blunt that it is the one area where the Rozena beats the Tenergy series, with higher fault tolerance in both attack and defense. It uses the same Spring Sponge but in a softer, more forgiving form, with hardness sitting between Tenergy 05 and 05 FX, so it keeps a dynamic tensor feel while being far easier to handle. It is also notably less spin-sensitive, so you can produce your own spin on serve return regardless of the incoming ball. As an all-rounder it shines: hits, serves, blocks, the short game, loops and chops all come with ease, and it is a particularly well-liked backhand rubber. The trade-off is ceiling, with spin below Tenergy 05 and 80, roughly Tenergy 64 level, and speed that is medium-fast rather than explosive. It is a do-it-all that masters nothing top-grade, and it costs less than Tenergy.

What Reviewers Agree (and Disagree) On

Reviewers agree on control, forgiveness, low spin-sensitivity and suitability for developing players. The disagreement is framing: many call it an excellent balanced rubber on its own merits, while critics dismiss it as Tenergy-lite, a jack of all trades, or even leftover Tenergy with less spin and speed.

Who Should Buy It

Buy it if you are a developing or intermediate offensive player, especially on the backhand, who wants Butterfly Spring Sponge feel with maximum control and forgiveness and an easy short game. It is not the rubber for an advanced looper chasing maximum spin and speed.

FAQ

Is the Rozena just a cheaper Tenergy?

It shares the Spring Sponge and a similar dynamic feel, but it is softer, more forgiving and more controllable, with less spin and speed than Tenergy 05 or 80 — and it costs less.

Is it good for beginners?

Yes — control and fault tolerance are its strengths, which is exactly why coaches recommend it to developing offensive players.

How does its spin compare to Tenergy 05?

Lower — roughly Tenergy 64 level. Its edge is control and consistency, not maximum spin.
