Very good batteries
Quality of the batteries are VERY good. Keeps a decent charge. I've used for 2 years now.

They work great so far.
I bought the batteries to fit my Makita laser, for general layouts in construction. They seem so far to last as long as the OEM Batteries, and they work with my OEM charger and the laser flawlessly. The only quirk is the first time I'm put one of these batteries on charge, the charger blinked as if it was bad. i took it off, put it right back on and it worked fine after that, The plastic casing is not near as nice as Makita batteries, however you get two of these batteries for 3/4 the price of an Original, so I believe it's acceptable. Will update if they don't last. But for the price you pay they are a great value. They are tougher to get into your battery slot than OEM batteries, but my old one used to just fall off sometimes so I'm not complaining.

Good value
Good value I have a set of makita 12 volt drills very old and the batteries just gave out. To replace with original batteries would have been more than the set cost. These seem to work well and my charger works fine with the new batteries. They are lighter than the original ones. Not sure about longevity but seems to be worth it. My original batteries were the 1016

Good replacement
So far so good...got these to for my Makita 12v and they work great so far. They snap into the saw with no issues, just like the original. They do not snap into the charger, but they still go in properly to get a charge. great addition to your original as these little 12v die out quickly so you'll have 3 other charged batteries to keep cutting

Batteries won’t charge or work with tool
These batteries will not work with the Makita charger designed for BL1021b batteries. They are useless!

They work....sorta.
They are compatible with the Makita 12vdc impact and drill. They take a charge up to 75% on the indicator. They do not have the same power as the original. The Makita's are my throw around tools. These batteries will not power the tools to their full torque. Disappointing, but at least the work, sorta.
