    Customer Reviews SummaryAI Summary
    Despite its low price in the 1000 yen range, this table tennis rubber is highly valued for its ability to confuse opponents by combining knuckle and spin variations. Evaluation varies significantly by user experience, with skilled users giving high ratings.
    ■ Frequently Mentioned Points
    • Produces knuckle balls easily that confuse opponents
    • Hard, low pimples allow mixing spin and knuckle shots
    • Excellent cost performance at a low price point
    • Suitable for learning cutting techniques
    • Requires time and practice to master
    ■ Representative Voices
    ▲ PositiveUnexpectedly high performance for a 1000 yen rubber. Light meet hits produce fast knuckle-like balls, making it effective both as an aggressive outer pimple rubber and for defensive play.
    ▽ CriticalNot suitable for serious club players pursuing competitive improvement. Better suited for casual play or learning cut techniques, so consider other options if serious improvement is your goal.

      I play an all-round/junk attacking style with OX rubber on the forehand and inverted rubber on the backhand.
      The big feature is that OX rubber is barely affected by incoming spin, so receiving is incomparably easier than with inverted rubber.
      Especially in doubles, if you really master it, your receives are almost unfair.

      If you're going to build a similar playing style to mine, I'd really recommend practicing your receive as much as possible.
      *Receive aces are pretty common too.

      However, since the ball doesn't grip the rubber, you need quite delicate ball touch.
      That just comes with practice though ^^;
      Also, some other sites say things like "since the ball doesn't grip it, you don't need to replace OX rubber very often," but I don't think that's true.
      That's because without a sponge, all the subtle feel for spin has to come from that single rubber layer alone.
      *Since there's no sponge to absorb the ball the normal way, the ball leaves the rubber even faster than with short pips.

      Once you start playing with it and get a feel for it, I think how you see table tennis changes quite a bit.
      If you're interested, please give it a try.

      gear refugee (Experience: 2〜3 years) A rubber like a musical instrument

      Reviews by user

      I'm playing a close-to-the-table blocker style with Spectrum S1 (thin) on my forehand and Cobalt α on my backhand, both mounted on a Gouriki blade.

      This rubber really makes you think of a musical instrument, like a trumpet. Just hitting it a little, it's not even easy to place the ball where you're aiming.

      But once you get a feel for the slipperiness and bounce and learn how to use it, it suddenly shows its real power.
      On top of dead-stop stops and knuckle blocks, once you can use a backhand meet-hit too, you get these terrifyingly fast-releasing knuckle balls that shoot in a straight line right into the opponent's court. Almost nobody can handle it the first time they see it.

      Flicks are easy to do, so it's easy to seize the initiative even off a receive, and against opponents who like to swing big inverted-rubber-on-both-sides tension shots from mid-distance while chanting "arc, arc," it won't let them play their own game.

      "Prioritize making it hard for your opponent to hit over making it easy for yourself."
      "Be prepared to stick with this rubber for at least a year."
      "Have a practice partner willing to put up with balls that are hard to hit."
      If that's the kind of person you are, it's definitely worth taking on the challenge.

      Ben table (Experience: 2〜3 years) This is insane lol

      Reviews by user

      It's meant as a defensive rubber, but it flies like crazy. Just a light meet hit and you get a fast, knuckle-ball type shot.
      The performance is good enough that it wouldn't be surprising if it sold for around 3000 yen...
      If you don't have much money but want to switch to short pips, definitely give this a try.

      Yuya (Experience: 2〜3 years) Cheap, yet… quality well beyond the price

      Reviews by user

      I'm a backhand-pips chopper and I have this on my backhand.

      It's only a rubber in the ¥1000 range, but this rubber is the best!
      The pips are low and hard, so at first glance it doesn't look like it would put much spin on the ball,
      but for pushes, blocks, and chops, you can easily mix in both heavy cut and knuckle balls.
      Start off receiving with knuckle balls, and once your opponent gets used to that, send a cut ball and you can score straight off the serve-receive.
      Also, the push produces a super knuckle ball that takes the opponent time to line up their racket for, so use it at key moments. You can score points with it even without aiming for a specific course!!

      Also, drives, smashes, and blocks are easy to vary in power and length, really showing off what it can do as a short pips rubber.
      Whether you hit it flat or brush it, you still get a decent amount of spin.
      I can't do the chiquita myself, so I'm not sure, but I bet this rubber can handle it.

      I'm an attacking player, but I found this cheap option for messing around with chopping in my spare practice time, so I bought it.
      I only chop for fun, but it goes in consistently.
      It doesn't put much spin on the ball.
      The pips are on the hard side, so I think you could get more spin if you have good swing speed.
      There's no sponge either, so it doesn't bounce much - I'd recommend it for beginner choppers.

      A piece of cut man back table (Experience: 2〜3 years) Lets you hit balls opponents can't return easily

      Reviews by user

      I'm a chopper, and I have it on my backhand.
      If I chop hard, I can put a good amount of spin on the ball and make the opponent think it's not spinning, drawing a net mistake, and if I return it without cutting, it comes back with almost no spin, which draws an overshoot mistake.
      I often hit balls that land short on my backhand side, and with a nice crisp feeling, I can easily place the ball to different courses.

      Reviews by user

      This is a funny rubber lol I bought it just for fun. It might be good for people who don't want to spend money on table tennis - purely in terms of value for money it's fine.
      But yeah, it's not suited for people who play seriously, like in a club team lol
      It's kind of a "sort of usable...?" type of rubber
      I can't really recommend it, but if you want to feel the history of table tennis or you're interested in old-school rubbers, it might be worth trying. I think it's decent enough for beginners getting into short pips chopping.
