Works perfect with my small portable Ryobi drivers
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

Utterly dead. Tried charging, tried their suggested "discharge and recharge" - utterly dead.
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.

Excellent
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.

Replacement 4V Battery for RYOBI Tek4 AP4001, get more power and runtime w/2.5 Ah vs. Stock 1.3 Ah
Well, I needed a second battery and I found this 2.5 Ah and man does it out perform my stock RYOBI 1.3 Ah. Price is important to me and RYOBI has higher TEK4 Ah repacement batteries, but wow was the price high! Low Priced / Higher Ah, how can you loose?

works well and just like the originals
Battery arrived quick and after charging it worked fine. Seems to be as advertized as far as power. Would buy again if needed
