Although the supplied tool does the job, but I would rather be proper tool to open the controller used.
Then started the first game - Super, the controller feels like new.
First impressions: Super.
Having the sticks for a good month in use, however, I noticed that the rubber has now worn very far - a lot more than it would have happened at an original stick at this time. The grip is still good, but the four surveys are almost gone. So I am afraid that these sticks will hold a maximum of six months to a year.
After all: The package contained two pairs, I can swap so again.
Conclusion So: the sticks are absolutely useful for the price, but they wear out pretty fast.
