00:25Over 4,000 sold, clean 5-star rating. Costs $4.95. Top pick if project needs proven,
00:34bulletproof baseline drive motor. Second one, cheapest pure workhorse. $3.14.
00:43Delivers 7 to 600 RPM on 12 or 24 volts. Full metal gears, reversible, 4,000 sold,
00:50flawless 5 stars. Buy this if building budget combat bot or swarm drive where low cost beats
00:56everything. Third option, specialized build. Comes with built-in rotary encoder. Runs 6 or 12 volts,
01:05spans 6 to near 1600 RPM. Costs $5.87. Perfect for self-balancing robots or closed-loop PID
01:15control where will position feedback mandatory. Fourth unit, eccentric shaft variant. $3.90.
01:24Handles 6, 12, or 24 volts with speeds 7 to 960 RPM. Eccentric gearbox output shaft helps fit tight
