I have been a Tenergy05 player for some years, however, I was always looking for a cheaper alternative. After testing quite a lot rubbers I finally found the Rhyzm 425 with similar characteristics as the Butterfly rubber.
With good control it is easy to do both slow and fast, well-placed blocks.
Topsins at the table are no problem, even against heavy underspin players. The only thing where I liked Tenergy05 better is at counterlooping a few steps behind the table. It is no problem with Rhyzm 425 neither but the ball's feeling is slightly worse.
As the rubber is rather spinny, you can generate a lot of spin varieties with your service.
On average I play six hours a week, after three months the rubbers' characteristics decline noticeable and I buy a new one.
I use this rubber both on my forehand and backhand with JOOLA TPE Nature blade.
In conclusion, I have been playing Rhyzm 425 for two years now and for me it is a good alternative to expensive Tenergy05.
