I have received my shell integrated battery after 3 days very fast sending and own product and aesthetic level really disappointed not too big and perfectly marries the iphone so very happy in terms of the battery j liked them worries since 15 days to use when I have to charge ca nickel and solid running low at the moment. I recommend it to everyone else I have to order one for a friend very surprised that a shell can recharge a iphone and at the same time protects the while maintaining your aesthetic so voila.a blue Varte c is partiiiiiiiiiiiiiiiiiiiiiiiiii.momo
