Planning to get myself a Ps vita Nyko Power Grip. Is it really useful and more comfortable for gaming? As i know, it charging ps vita while playing, i worry it affect ps vita battery life as well. I dont think it is good for console or device if charging while playing...I hope to get some comment about this product. Thanks!l

I'm using the non-battery one, which you need to take the vita out to charge, unlike nyko, you can charge vita while wearing it.

If your hands are big like mine, its a god send. Try them first before you buy.

i get myself non-battery ady. the model is like nyko, there a hole can be plug for charger wire. So im happy with it.

What brand and how much? Mine Pega but no whole T_T

I did have the 'always charging' phobia when I first use the Nyko Power Grip. But the comfort level itself is enough to outweigh the fear. But come to think of it, you can leave the Nyko's battery drained so it will not charge the Vita. I do find the Nyko's additional battery useful.
