This rubber is great. It's very well allrounded.But it excels in the looping/blocking department. A great rubber for hard blades. I recommend it to beginners and loopers who like soft,spinny and fast rubbers.

This is another winner from Butterfly. It's defnitely a soft rubber that is exceptional for looping. However it may be too soft if paired with a soft blade. High degree of control, better mechanical spin than the regular Sriver and El. Recommend in 2.1 so that the hitting game does not suffer.

Baby brother of the Sriver family. Built for speed gluers, not a very good forehand rubber because of strength has been sacrificed for the soft sponge. Very different when glued. Very good control.

Good rubber for almost any style of allround to offensive play except for hard-hitting. I think this is a great option for controlled loopers, but at the same time this one may be a bit too soft for other very aggressive players. Sriver EL may be a better option for most people looking for a softer version of Sriver.

Then again, if you aren't a very hard hitter, this one might not be a bad choice either. This version of sriver might just be the best considerind defensive play along side offensive play. I think this one is the best as chopping and giving feedback.

Entry level rubber for beginners like me. Very durable, plays like 90% new after more than 2 months. It's a classic Euro/Jap rubber with no tack at all, so to get lots of spin the ball really has to sink into the sponge, which is very soft. So not much serve spin from it. I've found I'm much more suitable for cheaper Chinese rubbers.

Non-speed glued, this rubber lacks ALOT of speed and spin, would'nt reccomend for close to the table loopers like me...

When I moved away from Flextra, I started using Sriver FX on my FH. Oh boy. I used Sriver in my BH and I must say I loved the combination.

Even though some users say this is a better BH rubber, I always found the combination work for me. I looped well with the FX, it delivered the goods pretty much like Sriver but I felt it had more kick to it. Another favorite. It lasts a lifetime too.

I love playing with FX farther from the table and tomahawk serves with FX are just killer (not much difference from Tenergy 05 so you can be the judge).

I'd say this is a great rubber from beginners to advanced players. Another classic!

Good for beginners with a hard racket

A good rubber for offensive players,slightly tacky and a good racket for looping.

very good rubber fore bh.
i play with sriver fx on fh and bh 1.7 mm. its very spinny and the control is very high, but it is a little bit slow. good fore a allround player on bh.

pretty good backhand rubber. not nearly enough speed for forehand, but is overall a good-enough kind of product.

haven't tried it speed glued, but I suspect it'd be a candidate for forehand in that condition.

it's just the right speed/spin/control/softness for a proper beginner (i.e. child starting out with a coach.

I borrowed this rubber during a prctice match..... On a primorac carbon blade....First things first...

Speed: Not what I expected not that fast but good for a beginner(good enough for backhand)

Spin: Also good enough for a beginner....(Missing that extra spin on serves and brush loops)..

Control: Excellent... very comparable to a Mark V!... Might be good if fitted in a hard all wood blade...(primorac) original

Overall: Nice rubber for beginners but not good enough for pros or semi-pros at least....

Note: If you plan to buy this rubber you might as well buy the Mark V...(original) or the
Mark V XS

Hahaha. Just tried it speed glued and it was so cool. At first its a little bouncy but after that you start to feel the power and the high control which comes like from other dimension. Now I realise that this rubber is almost unusable unglued. For the first time glued it felt like i has about + 30% power and spin. after about 4-5 reglues i guess it will have no mercy.

1.9mm Sriver FX

Paired this with an OFF bat and currently uses this on my FH. This replaced my Yasaka Mark V MAX on FH and I'm very glad with my decision. I also love the softness of the sponge.

Control is very good. Loops and chops are consistent. On smashing dept, you should put a lot of power into it. Definitely a very good rubber.

Its one of the grestest rubbers on the butterfly history. Its great for the players that doesnt control the backhand (as me) U can loop chops easily and continue attacking with no problems

This rubber is only for those that lack confidence to put the ball away. A good player (i.e. good footwork and power) would smach the crap out of the ball if one looped with this. I would recommend a thinner sriver or sriver el for more control over this rubber.

this blade is quite good for those who just starts to play table tennis. it has balanced speed, spin, and control. but i can say that the spin and control is better than the speed. compared to the price, i really recommend this for beginner and experienced player

honestly this rubber is really slow. It has amazing control. you can do all strokes with it easily.
I use it as my backhand (sponge 2.1 mm)

This was a rubber made for speed glue, which of course is now banned. It's spin and speed is just ok; this rubber is now for control. It is average at best for spinny serves. It's great for a beginner looking to develop their shots; I am using it to work on my backhand, which is much weaker than my forehand. It allows you to develop the correct technique without worrying about missing. It is light and soft and completely non-tacky. It plays well close to the table, further back it requires some effort.

That being said, in max thickness it can produce some pretty fast backhand flicks. Not as fast my Vega Europe, but still enough to win the point. It feels a little dead sometimes, but it gets the job done. Soon I'll be able to 'graduate' from my sriver fx once my technique is sorted. :)

my very first jap rubber! 2.1, used in my FH on a vsg 1000 and 2000. anyway, it suited my slow spinny loop way back then, chops are high as sky, flicks are hard to do since its bouncy. speed is not the issue, you sacrifice it for spin.

For many years my backhand black 1.7 mm perfect for learning topspin technique.Not very fast,but control at the highest level
