I recently bought one from here http://goo.gl/bDPUkY and I think I made the right choice. It has two motor and gearbox sets to have wheels running in different directions and great for hobbies or educational project.</p>

I recently purchased some 6 volt replacement motors from Pololu (http://www.pololu.com/product/1117) that fit perfectly into the gearbox and move well at both high and low pwm's.</p>

This sounds obvious, but I think some extra recommendation could be useful.</p><p>What is the recommended driver shield for an Arduino Uno given that the Ardumoto is out of stock and the SN754410 is only 1A? The 1A is not sufficient as the motors are spec for 2A on stall.</p><p>There is a Pololu Low Voltage Dual Serial Motor Driver, which is recommended with this gearbox however I am having difficulty locating an appropriate H-Bridge digital line driver.

However, you can run the outputs through a motor driver board, such as the Ardumoto (<a href="http://www.sparkfun.com/commerce/product_info.php?products_id=9213" rel="nofollow">http://www.sparkfun.com/commerce/product_info.php?products_id=9213</a>), which will supply the necessary current and give you other nice features such as forward/reverse, etc. Check out the Robotics / Drivers section of our website for more information.</p>

I was able to get it to turn fully assembled with a "AA" battery (1.5vDC). Not really enough lube for all of the bushings on it, as well as gearing.<br>
It did come with mounting spots, as well as with mounting hardware -- a nice feature. Overall, I give it a thumbs up.</p>

I used it on a Sumo Robot, which weight ~1kg. My requirement was to push other sumo robots out of the arena. Therefore I assembled it in the "HIGH TORQUE" mode. The instructions in the assembly process were very straight forward, and I believe anyone can do it. Took me about 30 mins. I used the SN754410 to control my sumo robot. I also used the "Tamiya racing wheels" (white ones). One of the most important things things when using this gear box is that, you need to build a cover for it. Otherwise, the gear box is very fast, that it can pick up unwanted stuff from the ground. A good example is hair. My sumo robot turned out to be a good success and i highly recommend this product for similar applications.</p>

The included motors draw 2.2A each when stalled and are only "supposed" to be operated from 1.5 to 3v. Driving them higher significantly reduces their life. Take a look at the FA-130RA datasheet from Mabuchi.<br>
Mabuchi does make motors that operate on higher voltages and have lower stall currents which can be substituted with the motors that come with this gearbox.</p>
