Better and more affordable than Tenergy05. Extremely soft and spinny. It doesn't chip around the edges like Donic rubbers do.
The only negative I can think of is that it's quite heavy, very noticeable if you have a lightweight bat.
Rakza7 is even better than Yasaka's Pryde series, but I still use Pryde because Rakza is too hard to adjust to for me.
I recommend this to all the pros, anyone who uses Tenergy and feels like they could handle something even better!
