It is portable and compact and easy to use.  With that said it does have some negatives.  I am a professional roofer, it comes in very handy in tight spaces like under soffits over hangs valleys and chimneys. It works great on firm solid surfaces such as one byes, two byes and half inch or thicker OSB.  It does not however work as well on half inch or thinner plywood.  It does seem a little weak at times and you really have to put a lot of pressure behind it.  I like the quick charge time and the batteries seem to have fairly good run time.</p>...
