It's been about ... 6 months that I used!

The good side of these strips:
If you are tired of breaking your chopsticks weekly or receive full sticks together, Carbosticks are for you! Were relatively resistant rods (carbon) and instead of wasting several tips they break directly! They are also very light, ideal for quick play, and the carbon rod draws perspiration of the hands!
The bad points:
Changing the sound of cymbals, especially on the ride. Carbon gives a cleaner sound, more acute. More important, it is hugely rods that damage the cymbals, which can easily break them! (After quality also plays the cymbal, I personally have never broken cymbals, and I play on Meinl Byzance)

Before buying, I was playing chopsticks on many others, and I have therefore purchased for all my rods broke after 2 weeks ...

The price is not exorbitant, it's about 15 or 20 euros, twice a wooden stick ...

With experience, I'll try to find a way especially for less damaging my chopsticks and I'm not sure to repeat this choice because it is better than breaking sticks and cymbals!

I put 7, for the problems of cymbals, which are still major problems ...
