Hi,

So, I have the Canon 600D and always carry two batteries with me (one in the camera + a spare) when I go out.

I've been looking into Battery Grips and if they are worthwhile or not. I have read that it improves stability when using heavier lenses and as I have a rather heavy 70-200mm f2.8 lens, would having a battery grip really help me keep it stable?

If worthwhile, I've been looking at the Neewer BG-E8 for about $35 on eBay rather than the $200+ Canon.

Are Neewer generally a good knock-off or would you recommend something else?

Thanks
