## What reviewers say

**EGO POWER+ ST1623T 16" LINE IQ with POWERLOAD** — Only one whitelisted tester, Pro Tool Reviews, published a hands-on review of this exact model (design notes list Model: EGO ST1623T kit / ST1620T bare tool). PTR rated it 9.7/10, praising the automatic Line IQ feed that eliminates bump-feeding, the easiest PowerLoad line loading, excellent cutting power with low vibration, and a measured 1hr 4min runtime on high with a 4.0Ah battery, while flagging that fast line breakage around hard obstacles like fences can outpace the auto-feed with no manual override.
