So far it works great. Good value, and it arrived quickly.

Very happy with delivered product. Works as stated and seller company is very motivated to make sure as a customer you are satisfied!

Bought the batteries and after one usage first one malfunctioned and would not charge. Tested against a Milwaukee 18v battery of the same size and type. Both fully charged and after only 2 months use my 7 1/4 circular saw would not even make one cut without shutting down with the only working battery I had left. Don't make the mistake I made of thinking you can save a few dollars and also think that batteries made who knows where and with who knows what inside parts or where they came from represents quality of any kind. My Hundred dollar purchase is now in the trash and I would never buy anything but a Milwaukee battery ever again. In closing and in my honest opinion I suspect these blocks/type 18V batteries are being produced so they appear to be a block 18V battery but only have the power of the smaller pancake battery because this is exactly how these batteries performed from the start. Waste of money. Waste of time.

Batteries are a little loose while on tool but works fine so far.

I got this for my husband and he LOVES is .. it’s lightweight but powerful. Great for a quick patio clean off

Perfect replacement for OEM. Has the same layout and battery charge check. 3 months in no problems.

Even though they aftermarket they work just like the originals. Strong pounds of torque and battery life is good can’t complain

They fit good in the tools but only last a fraction of the time.
