EGO ST1623T Line IQ Review: The Easiest Trimmer for Homeowners

EGO ST1623T String Trimmer Review

When it comes to making lawn work painless, EGO leads the pack, and the ST1623T Line IQ is proof. It’s the most user-friendly string trimmer we’ve tested, packed with homeowner-focused features like a telescoping carbon fiber shaft, push-button line loading, and smart automatic line feeding.

This isn’t the most aggressive trimmer on the block — you won’t use it to clear a fencerow of waist-high weeds — but for regular yard maintenance, it’s about as convenient as a trimmer gets.

Power and Runtime

The ST1623T runs at two selectable speeds, topping out at just over 5400 RPM in testing. Cutting performance isn’t class-leading — it took 18.1 seconds to chew through our test swath (ranking near the bottom of the pack) — but EGO makes up for it with runtime.

With the included 4.0Ah battery, we clocked over 51 minutes of trigger time at high speed. That’s nearly double what many competitors manage, and if you swap to a 2.5Ah pack you can shave weight while still getting around half an hour of cutting time.

Ergonomics and Comfort

The trimmer weighs 12.7 lbs with the 4.0Ah battery, but the telescoping carbon fiber shaft helps distribute weight evenly and adjust to your height. It’s front-heavy compared to pro trimmers, but nothing unmanageable for residential use.

Vibration is impressively low, tied for second-best in our tests, which means you won’t get that hand-numbing buzz even after 40+ minutes of trimming.

Line IQ and PowerLoad

Here’s where EGO really flexes. The PowerLoad system means no more fussing with spools — just feed the line through, press the button, and it winds itself. On top of that, Line IQ automatically feeds line as you cut, so you’ll never bump the head again.

The only drawback? Not every aftermarket line brand loads and feeds smoothly. Stick to EGO’s own 0.095-in. line for the best results.

Price and Value

At $219 bare tool or $329 as a kit with 4.0Ah battery and charger, the ST1623T isn’t cheap — but for what you’re getting, it’s worth it. Between the premium shaft, automatic systems, and long runtime, it’s one of the best homeowner trimmers you can buy.

Bottom Line

The EGO ST1623T Line IQ is a homeowner’s dream: quiet, powerful enough for weekly trimming, and packed with convenience features that make it almost effortless to use. If your yard work is more about edging and grass trimming than fighting heavy brush, this trimmer is easily one of the top choices on the market today.
