Despite the modifications, the US Army still found the design underpowered after the tests concluded in 1923. It was also considered to have poor maneuverability and was found to be mechanically unreliable. Additionally, it was found to have too confined crew space and was made with bad workmanship. The design was totally rejected in 1924. The cost of the tank for the tests were $ 82,000, not counting the actual cost of the testing process.

The tank featured armor of up to 2 inches (51 mm) of steel. Its top speed was 30 kilometers per hour. The turret housed a main 57 mm gun, as well as two machine guns for secondary defense. It weighed 23 tons.
