Im writing this as an American living inside the United States, so this product may vary per person. This product shipped in perfect condition and was good for modifying and even works with an arduino. We used this for our bot using a custom radio and a 9V battery and it is very powerful. this is not a bot or fake I actually bought the thing

Easy to install. Definitely destroys test objects. The problem is that it makes the robot undriveable. Hopefully we can fix thos with some weight and balance adjustments but it seems to make the bot much too heavy in the front/light in the rear.

Used this with a 3s battery and the bloodsport bar. It does some serious damage and its pretty loud as well. putting it together is easy too.
