I got these two days after I ordered them and they work great made real well and durable. There small enough I can fit them in my pocket or my purse and very easy to carry anywhere. They also charge my earphones pretty fast there very handy to have when I'm having a real busy day and can't get to a charger right away it came with two so I also have a extra in case my husband is needing one for work plus my kids like them too. They also have a flashlight built in them so if its dark I still can hook my earphones up with no problem or if I'm just needing a flashlight to unlock my door at night there very handy to have and I'm very happy with them if your needing one this is the set to get I haven't had any problems out of mine.
