How good are these gear boxes?

Has anyone had experience with these gear boxes? If so, how good are they?

It uses the 540 motor which is cheaper, bigger and more widely available than the 380/390 high rpm series. The gearbox can use the same design. At $150, it is a poor money value. I paid half of that for the excellent Heng Xin gearbox with the red 390 motor.

The 540 is a more powerful motor. If the bigger 1/16 scale RC tank can accommodate it easily, it should be a no cost upgrade. The 540 is used a lot in auto industry. The larger production scale should make it much cheaper. I hope that a 540 gearbox will come down in price a lot shortly.
