4x4 & 5x5 180° Turns Only! (Easiest Method)

Here is the easiest method to solving the 4x4 and the 5x5 using only 180° turns! The methods are pretty similar so I decided to put them in the same video. This was a fun challenge, and if you guys have any other challenges, please drop a comment.
Sorry for the long break, I have a lot of homework. But thanks to you guys for all the support, last month was the best on record!
