You can only earn credit for one US review for the duration of the new 4th rendition of the program... but can make as many YouTube saber reviews as you desire. Make sure that for the one that you decide to submit for US approval... that it contains/falls within their guidelines. Have fun and strive for the extra credits by making an awesome video that US also decides to use to promote that specific saber.

If you don't meet their approval standards the first time you will do better with more confidence on your next ones.
