I liked the first T5000L I bought, lasted 40000 shots until I took it out and broke a motor tab... Pinion gear is amazing and holds up to some abuse. Held on by a hex set screw so it won't fall off, but it is half shaft. Extremely magnetic! 22 balls per second on a m120 spring. But it can pull back an m140 on standard ratio gears. I tested this versus the Systema magnum motor, no difference, none at all, and at almost half the cost. Brushes were like new when I pulled it out; I even use an active-breaking mosfet switch that wears them down 2% faster.
VERY magnetic, VERY powerful
Half shaft pinion (stays on)
Strong motor brushes
Half shaft pinion (hard to find when stripped)
