I was lucky to get a coupon to buy this at a reduced price but to be honest I would pay full price!
It's a powerful beast and has already recharged my phone and my son's (he's on YouTube a lot!) it doesn't take long to charge and when it is fully charged it is ready to recharge your phones/tablets. It's one of the more powerful ones out there that you can buy.
I'm really impressed and I think it's an amazing piece of kit - I hope to get another just for me!
