## Customer Reviews

### ⭐⭐⭐⭐⭐ Works just like original
*by R***B on March 18, 2019*

I tracked down this battery to have a spare for an "iBaseToy" H816H drone. This one fits , charges and performs just like the original. You can't ask for that. I think a lot of this stuff is made in China and distributed under multiple product names. So, there's a lot of potential to mix-and-match if you're persistent..

### ⭐⭐⭐ Spare batteries
*by T***D on January 7, 2020*

I bought this as a spare battery to my drone. It's great that it is portable and fast charging but it only has a short battery life.

### ⭐⭐⭐⭐⭐ Good deal!!!
*by M***R on March 6, 2019*

Great second battery!!!
