I originally bought the 2 tool combo earlier this year with the drill driver and small circular saw and then followed by the newer hammer drill 2-battery combo. The regular drill driver is average, the 5-1/2" circular is close to garbage, as the blade, housing, or shoe is deflecting during the cut--couldn't get it to cut straight or plumb and couldn't detect any play anywhere, it would just deflect somewhere along the cut. The hammer drill is a beast for $99 with 2 batteries. Drilled (36) 3/8" holes, 2-1/2" deep into an old concrete pad. Took 3 hours and the battery would be toast after 6 holes, but that drill was never meant for that kind of work. Highly recommend that tool. Would probably get their 1/2" impact as a backup if it's built off the same platform.
I actually have a collection of Ryobi *corded* power tools: circular saw, jigsaw, drill driver, heavy duty hammer drill, reciprocating saw, small angle grinder. All of them are the blue color and not the newer neon yellow/green. All of the corded tools, save for the jigsaw which was a pain to cut with a guide (yeah, I know they're not for straight cuts), have held up well through 2 bathroom renovations, a small studio build, various landscaping work, and now working on the garage build. After 6 years, the most used circular saw is just getting some play between the shoe and body, but accuracy for what it is used for remains unchanged.
