If you omit the locking technology, there would be five star. In relation to capacity is the price-performance ratio in order. Somehow here but design to fight functionality. The shifting mechanism is kind of pointless, because he does not keep. The part slides back and forth and can not be locked properly. Just like in the picture it just looks when the stick is not moved, but he is already thought to take away. I have to keep him due to the low price, but I would think I would prefer a different model in the next purchase.
