I've never used a battery grip before. So, other than the authentic Canon brand, can anyone recommend a less expensive brand for battery grips? I am looking to purchase one for my 6d and one for my 7dII and am on a tight budget. I almost snagged a brand new Canon one for the 7d II for $110 but snoozed for a minute and lost out.

Someone on Facebook recommended Neewer brand, saying it has worked out well for him. Are off-brands safe to use as long as you put real Canon batteries in them? I just fear that there is a chance of messing up my camera going off-brand. Would it be better to just save my pennies and buy Canon (new) or wait it out for another Canon one to show up on the used market.
