At first glance the product looks very good and effective. In my case, the first defect is that in order to place the controllers on the charger must remove the protective sleeve, and strap on the controller as gene positioning it on the charging stand. It's already very annoying. 3 controllers, I had 1 original and 2 which were from China. They have become unusable (even with batteries) after 2 or 3 refills with Battery and Charging Stand. They work very well before using this product. I do not recommend this to people who do not have that original joysticks. In my case, I do not use anymore. Too many doubts about the product, and the knobs are too expensive to take such a risk.
