Here's mine. It works fine & was cheap but you get what you pay for. I still may get the Makita someday.
I got this long before the Makita LXT (18V) came out or was announced & there was only the XGT (40v Max). This is actually molded from the XGT model.
I still need to make me new labels for it. I'm calling mine the Milkita.
Just a word of caution with those battery adapters. For most, the low voltage cutoff is built in the tool and not the battery like Ryobi. So in my case using an M18 to Makita have to pay attention to battery level cause nothing will prevent the battery from draining too low.
In addition, the ones with a USB port. The USB circuit will cause parasitic drain on the battery so when not in use for long periods of time, remove the battery. Otherwise eventually it will over drain the battery also.
That bugged the hell out of me & the USB port is useless to me. I took care of that by disabling the USB circuit. No more parasitic drain. I put a cover on the USB port also
