What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
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. (1 sourced review, 1 lab-tested.)
Praised: Automatic Line IQ feeding eliminates stopping to bump-feed the head; PowerLoad self-winding makes line changes the easiest tested; Excellent cutting power with low vibration.
Flagged: Line can break off faster than the system re-feeds it around fences/hard obstacles; No way to manually extend the trimmer line.
