1/2 cordless impact opinions

I bought a Ryobi on a black friday sale, $99 1/2 impact, 4ah LI battery, charger, and carrying case. It works great, it is way stronger than my dewalt 18V 1/2 impact(older model).

I really like the Ryobi stuff but some of it is lack luster. The Sawzall and drills are pretty weak compared to dewalt. I wish I could get my 18V Ryobi batteries to work on my Dewalt Drill and Sawzall.
