Cheap, poorly made charger. I wouldn't buy again.
The batteries seem to work and take a charge. But the charger is solid piece of junk. The 5 volt power port is poorly soldered onto the board and broke as soon as I tried to plug in a cord.

The charge biggest POS didn’t even get to use it
I’m giving it the benefit of the doubt with the Assumption that the batteries are good the charger broke as soon as I try to put the USB into it the correct way it just pushed and I’d rather spend five or $10 more knowing the Chargers not going to break before I even get to use it

Batteries work great
Batteries were cheap and work as well as the original that came with my drone.The charger died after the first use - wouldn't turn on again - so one star loss for that.

Wouldn't recommend it...
It took them more than a week to ship out and another week to arrive. I received packages from China that arrived faster. Right out of the box I could see that the charger was broken. The micro USB port on the charger isn't even attached to the unit. I haven't tried the batteries since I have no way to charge them but I'm not holding my breath. I would return it but that would likely take weeks/months. It's a cheaply made product so even if it works I wouldn't expect it to last long at all. I wouldn't recommend this product.

Batteries work good just dont let it hang from a plug or fall off a counter while batteries are attached.
The batteries work great. Not really any different than the original. My only issue is after a week the charging unit broke. The cord is short and while the batteries were on, it fell off the counter and the part that you plug into came out.

Charger is poorly made
Batteries looked good, tested first one. The charger broke upon first use, not worth the time without a proper charger.

I would not recommend this product
Just received this unit, plugged in the batteries, not all of the lights came on on the charger unit, I had to move the wires around to get the charging lights on. Any slight movement of the wires stops some of the batteries from charging.
