A little skeptical when ordering seen the price difference (especially with 2 batteries included), I expected a bit of plastoc I would use only traveling for greater autonomy. At the reception, I was pleasantly surprised and the grip will remain permanently on the device in the end.
The grip is easy to install, seeming material be of good quality and identical rubber coating to the NPC. The 2 batteries are recognized by the original charger and the AFN. They load properly without heating. The additional rack for batteries is provided but not yet tested. The remote control is offered very nice, basic, simple, functional.
After some tests, the handle is closed and the whole is firmly held in hand. Orders grip respond as well as those of the NPC, although we can see a light at the lower quality knobs and dials.
There is more to see and use the holding batteries, but even without that, I recommend this article.
Edit: after a month of use, I confirm the quality of the object and robustness. However, not surprisingly, the batteries are bad. They take the load, are reliable, but less efficient than the original battery.
