Yep, once you start with a brand it's the battery costs that matter a lot.
It is amazing to me Dewalt, Makita, etc what they have done to expand. I see the stereos, coffee makers, I even saw dewalt put their name on drywall knifes.
BTW ............ if you listen to music on the job I have gone through quite a few bluetooth speakers trying to find the combo of loud and quality.
I don't want to admit how many. LOL!
Anyways I finally found one that just blows me away if any of you looking ............. Look up on Amazon for the W-King 60 Watt
