The Genie Signature Series 4062-TKNMSO is the outlier here: a screw drive rather than a belt or a chain, using a rotating steel rod to move the door roughly twice as fast as the alternatives. The Spruce's tester ran one for six months and clocked the door opening in about ten seconds, and the 2 HPc motor is the strongest on this page. Genie backs both the motor and the screw with a limited lifetime warranty. Two honest caveats: only one accepted publication has tested this specific model, so its score rests on a single review, and a garage-door professional quoted in that very article is critical of screw drives generally, calling them loud by default and maintenance-hungry.
- — The Spruce's tester measured the door opening in about ten seconds — a screw drive moves faster than a belt or chain
- — 2 HPc motor, the most powerful in this lineup by a wide margin
- — Genie's limited lifetime warranty covers both the motor and the screw drive itself
- — Only one accepted publication has reviewed this exact model, so its rating rests on a single test
- — No smart connectivity at all — no Wi-Fi, no app, no voice control
- — The motion-activated light is dim, which The Spruce lists among its two objections
