Expert analysis by Ezra Maddox
Ezra Maddox
Expert ReviewerContributing Editor
Ezra brings contractor‑grade pragmatism to Review Atlas, reviewing drills, drivers, and smart thermostats with equal skepticism. He checks torque claims, battery cycles, and installation clarity so weekend projects don’t turn into Sunday panic. His “good, better, best” picks reflect realistic budgets and skill levels, fitting the project—not the hype.
