With spivo you can measure the speed of the upward movement of the racket, which is responsible for the topspin, as an acoustic sound. Both supplied spivo work well for me and there is a creation between topspin (observed bounce of the ball in the other half, I have tested without opponent once with some test shots) and intensity of sound. They are also very well suited for training with the ball wall, because you can’t determine the spin from the bounce of the ball, but you can hear the sound. Since Spivo is based on a simple physical principle, does not need electricity, is easy to install and use, a brilliant idea. It’s just a pity, but due to the underlying physics it is perhaps inevitable that there are two speed ranges for each Spivo to which they respond and a “measurement gap” in between.
If you play more topspin, the whistle gets louder and louder and everything fits. If you pull through only a little from bottom to top, it whistles even with very fast strokes. I do not understand why it whistles in this case. Therefore 3 stars.
The faster the swing, the louder and clearer the whistle has to be to play more topspin. It is important that the whistle is already audible before the hit. Otherwise the ball has nothing to benefit from it.
Why?
As you can see in our video (https://youtu.be/M4N_34f333E), spivo® starts to react at 300 rotations per minute (RPM). This is not much, but useful to teach children how to learn topspin and is determined by the physics of the whistle.
Therefore, it will whistle easily (‚breathy one’) even on fast strokes with more flat swings. Nevertheless, this is also correct. Because if you hit the ball very fast with a slight upward movement, you will also play topspin, but very little. That is why you have written correctly that it becomes louder and clearer with more topspin. That is how it should be.
So everybody can decide for himself at which speed he wants to play how much topspin. Hopefully that helped. Good luck!
Bought in August and tested until now. My opinion is in advance, very positive.
PRO’s:
+ solid
+ intuitive and simple to increase spin
+ playing fast and hearing how much spin was there at the same time
+ possibilities are huge. Even when serving, you can choose not to play any spin to “hear” the pronation. Very good.
+ weight is so low that it does not bother. Sure thing, for real experts it is noticeable.
+ the idea of direct feedback is great.
+ after using it, you can even continue to play very confidently and fluently. Awesome.
(Use it now always selectively when I need it).
Neutral:
o due to the plug connection, spivo® sometimes comes out of the racket when a direct hit is made. Which means the cap comes off. The rest remains stuck in the strings. But this is only the case with hard hits, so it is no problem, but you have to fetch the cap for a short time and pin it back. Therefore a “neutral” point.
Con’s:
– you should really watch the video about the difference between ONE & TWO. In the beginning there was no such thing and I didn’t really understand the difference.
You only noticed that the whistles sounded different. But with TWO I didn’t realize that it takes so much speed to hear a clear and clean whistle, but the first whistle is slower than the spivo ONE whistle.
A small contra, that’s why the full 5 stars are available. Because the video has improved a lot.
A clear recommendation. I hope my rating can contribute something to support this great idea and product. Good luck!
Respect! I am a trainer myself and was very interested, but really skeptical if the promises can be kept.
After 4 weeks of active use with my players, my conclusion is:
The result is great! 90% of all players have developed very positively.The other 10% did not want to try it. Everyone as he wants to.
Remains my favorite tool and recommend it diligently.
First time I heard about it on vacation in Florida. As soon as I was back in Germany I saw the advertisement on Youtube. (funny how that always works 😉 ) – bought it.
Now I always play with it and I am really happy. Thanks!
I am a coach myself and can easily motivate my players to play enough topspin with spivo. No matter if it is about high speed or beginners learning topspin, the players usually manage to make the right moves without any help. Great!
I ordered in the USA and at first I was really happy that it was here so quickly.
I have tested the product 2 times and so far I am satisfied.
I am looking forward to the next weeks. I am curious how the result will be in the long run.
I will report.
I have really improved in the last 3 weeks.
Feels very comfortable and I have much more control. When I accelerate there are much less balls flying out. Unless I hit it way too high. 😄
I really like it. It is now always used when needed.
Play collage tennis myself and I am really surprised.I play spivo TWO because I’m a classic high spin player and I really have to say that I was surprised about how much more there is to play. But when you have a lot of swing speed for yourself, you can really hear it clearly.I play spivo TWO because I’m a classic high spin player and I really have to say that I was surprised about how much more there is to play. But when you have a lot swing speed, you can really hear it clearly. Let’s see how it is now in the indoor session 😀
Hi Philipp,
that pleases us very much!
If you’re accelerating so much, why don’t you put the spivo® down in the racket for indoor play? Then you can accelerate even more, but the sound will simply be quieter. Even with so much speed, you should still be able to hear your stroke just for you. – 100% –
Just try out which spivo® fits for you at the bottom of the racket.
Have fun!
I am quite happy. It’s really a great tool. Especially the principle of direct auditory feedback is great. My kids are excited too. Only my wife says that with her own backhand it is not working 😉.
The feedback on the kick is also great – my whole family could benefit from it.
Whistles also with Slice. Therefore it is not true that it only whistles at topspin. Nothing whistles on straight, but whistling loud before hitting can also be a slice if you swing from top to bottom instead of bottom to top.
Hi, Noah,
That’s right. But is that a problem?
We think you have even more possibilities to train with spivo®.
What a pity if you see it differently. But that is up to you.
Hopefully you are still satisfied with your topspin result 🙂
I was so looking forward to playing for the first time and it was absolutely worth it. I play LK 18 and can play faster now and still feel safe. Road to Lk10 I am coming. 😀
I bought it 4 weeks ago and played with it regularly for the first 20 minutes. My feeling for the spin has become much better. You can really concentrate on the ball after a few times and just subconsciously listen to the sound. Because then you only notice it when the whistle was not so good.
In the beginning I had difficulties to find out the difference between 1 and 2. Then the video came up on YouTube and it was easier. Could have been done a lot earlier. Still great!
I’ve only played tennis once and I have to say that it works when I throw and drop the ball myself, but I can’t hit the ball when I have to play the ball back and try to play topspin.
Hello, Adam,
if you have only played tennis once, then topspin will generally overload you.
So let me help you a bit: Your most important issue will be to hit the ball clean and to be able to determine the direction where the ball is going. We have no complaints from you, so I hope you will want to use spivo® again later? My suggestion: First of all, try to play back and forth 10 times with a playing partner safely and without problems and to have your contact point far in front of your body. The best way to do this is to watch the videos on our Youtube channel. I hope that helps you. Good luck.
I was unfortunately injured. After a break, I decided to buy spivo® to get back in shape faster. I am really glad to have done that! I didn’t expect to be back in the game so soon.
Ordered. Been there within 2 days. Tried out directly. Works!
In the beginning I was hitting it with the ball from time to time. Then the cap flew off.
Plugged it back on as described and it could go on. Now I get a feedback how much topspin I play, but also how clean I hit the ball. 😀
Hi Carsten,
Thanks for your great feedback. For the kick serve, put spivo® at the bottom of the racket (damper position). Then you have to swing a bit faster but you can do it on serve. This is explained again here : https://spivotennis.com/knowledge
Have fun!
