Review: Great Quality Multimeter for the Price - I’ve been using the Klein Tools MM325 Multimeter for a while now, and I’m really impressed with how well it performs for both DIY and professional use. The build quality is solid—typical of Klein Tools—and it feels durable enough to handle daily use in a toolbox or on a job site. The display is clear and easy to read, even in lower light. The auto-ranging feature works accurately and saves a lot of time when switching between different measurements. It handles voltage, continuity, and resistance testing reliably, and the leads are sturdy with good flexibility. One of my favorite features is the backlight and data hold function—it’s a small thing, but it makes a big difference when working in tight or dark spaces. The battery life has been great so far, and the protective rubber case gives it a rugged feel that inspires confidence. If you need a dependable, mid-range multimeter without spending a fortune, the MM325 is a fantastic choice. Klein’s attention to detail really shows here. Pros: Sturdy and well-built Accurate readings Clear backlit display Great value for the price Cons: Doesn’t measure milliamps or microamps (not a dealbreaker for most) Slightly bulky for small tool pouches Verdict: Highly recommended for electricians, HVAC techs, or DIYers who want reliability and ease of use without going for high-end professional meters.
