If you are starting up, and are on the legacy from the dad and begin to collect some affordable second hand tools that are still in good condition, you'll always find makita and dewalt are most popular.

So in building up your rig, why not grab both, just grab what you came across and quickly build yourself up and start making good dollars by doing what you are good at.

This little adaptor allows you to use makita batteries on dewalt tools, plus, it got the fuel gauge indicator. So now you won't be annoyed when picking up an old makita battery that is without a inbuilt fuel gauge.

It's build to last, but still comes with one year worry free warranty.

Disclaimer: all adaptors can only be used between your tools and batteries, they are not designed to be used with the charger. And logically if you got the charger, you should get the adaptor the other way around right? :)
