4 out of 5 eggs

Pros: Works as it is supposed to. All lights and functions work fine for me. Small form factor.

Cons: For my phone, (Atrix2) it only gives me one full charge. The phone is 3 years old and battery life isn't what it used to be. So in all fairness that may be a factor. Got it for a backup when kayaking, not sure it fills the bill

Other Thoughts: Definitely worth it if on sale, I got mine on shell shocker
