Expert Reviews


What reviewers liked

When it comes down to simple preference, the MultiMaster is my favorite of all 25 models we tested and earns the starting role in my arsenal. It’s the overall design and ergonomics that I’m willing to trade-off some cutting speed to take advantage of. Unless you need the higher performance of the SuperCut, the MultiMaster get my highest recommendation.
Premium, high-quality construction. Weighing in at less than four pounds, the MultiMaster 350QSL can be used for long periods without putting any strain on the back or arms. This lightweight design, combined with an ergonomic handle and reduced vibration, makes for heightened control of the device.

What reviewers didn't like

The MultiMaster comes in under 100 decibels with a 98 dB(A) measurement. That’s quite a bit higher than the 92 dB(A) of Milwaukee’s cordless model
Very expensive.
