The review warned me that it was too small to easily hold the phone and it had problems charging through a case. Both issues are true...

Works VERY well on iPhones; not so well on Samsung phone or tablets

I bought a 2 pack, one stopped working after about a month. The cord just falls out. The other one is still working so far

I have two of these at home and they only work half he time even though I use the quick charge cable that came with the devices.

I bought a 2 pack, one works great, the other one seemed to keep shorting out, it would work sometimes but now the cord just falls out where you plug into the unit. I tried a different cord to see if it was the cord, but same thing happened. The plug in hole must be damaged. Very disappointed because I do like the one that works just hope it keeps working.
