## Customer Reviews

### ⭐⭐⭐⭐⭐ Works perfect with my small portable Ryobi drivers
*by J***R on March 29, 2021*

Works like a charm and costs less than the Ryobi brand. No issues at all with charging or operating in the tool. Solid construction and excellent overall quality

### ⭐⭐⭐⭐⭐ Excellent
*by K***. on August 21, 2023*

These are just as good as original Ryobi batteries except better, because they are higher amperage. They will spend the driver a little faster and have better torque.

### ⭐ Utterly dead. Tried charging, tried their suggested "discharge and recharge" - utterly dead.
*by K***A on December 12, 2020*

Set it to charge - the charger didn't even recognize it at first. Then it turned on briefly - but it didn't hold a charge. Dead, even after a full charging period. Even tried the "discharge and recharge three times" method listed in their instructions (in tiny print) --- nothing. Dead. So I contacted customer service, because the ratings were pretty good - I'm sure it's a minor thing. And Customer Service - Zero Help. First, they want you to take a video of charging, and attempting to use it. Then the video will get rejected multiple times, unless it's less than 6 megs. Then they'll tell you they won't be able to open it, so please send it to their hotmail account. They won't tell you what the hotmail account is --- but with a little searching, you can find their main website by googling Exmate, and their corporate email is a Hotmail account, so I sent it there. That was Tuesday morning. Come Saturday night, still nothing. Nada. But thankfully, Amazon Assistant at least understands (and it's a program) customer service - and refunded the dead battery. Go with OEM, the savings isn't worth the hassle.
