Two monts after buying this product, 3 out of the 4 batteries would only hold a charge for no longer than 5 minutes. I emailed the company and have not received any response. This item is still under warranty but you cannot use the warranty because the company does not respond. Do yourself a favor and buy a more quality product from a more reputable company.

These little battery back ups work so well. The charging dock means that they are good to go every time we leave the house.

Item arrived in great time and was as described. It came with a lot more cords than I was expecting, 2 Lightning and 3 Micro USB. I was slightly disappointed by learning the unit charges by Micro USB and the longest Micro USB cable they provided was really, really short. I was happy to find out that the batteries can be placed in the charger in either direction and still charge, so you can just drop them in without any thought and they will charge. The blue light coming from the batteries while charging is very bright, like nightlight bright, especially with all 4 charging. I wouldn't put them in a room you want dark. This can be a plus if you like nightlights though. I'll update this review once I can weigh in on their longevity, but at this point, I'm completely satisfied.

nice to have multiple charging units ready to go when we need it, only problem is sometimes there isn't enough juice to fully charge an iphone, even when the charge unit is fully charged itself
