Appearance:
You can see the original very similar, the rubberized surfaces are considerably larger than the Sony counterpart.
The neck, which leads from the cap to the grip surface, thicker than the original, and, unfortunately, hollow on the inside.
In the original stick the neck is solid and resists thereby more pressure and rubbings. In this one, the end is already pre-programmed, because at a certain degree of wear of the head simply breaks off from the neck. Here could possibly be improved with filling material or plastic filler.
Fit:
The Sticks simply slide over the tail, but not seat properly, thus they can be in an assembled controller upwards. It's frustrating. Sticking? Is an alternative, but why can not the same as producing something that fits?
Grip:
Grip Technically they resemble the original much, I could not detect any perceptible difference. Have they not yet tested for a long time.
Price:
The price is ok, but some quality compromises have to be made. Anyone wanting to use these sticks as a true replacement, must rectify itself. If you can live with the smears and its controller will still elicit a few months more playing time, is well advised here.
