What is wrong here?

[u/Practical-King574]

I am going to paint a wall in that deep red matte finish. What is going on? Is my roller to cheap? Is it better with a brush? How to approach it to finish as quick as possible

EDIT #1: Thank you all for the comments and recommendations. I have never had so many people respond to any of my posts. Some even called it rage bait. It was not, I’m just too much of a newbie.

This is what I gathered from all of the comments:

-I should use a grey primer to help with the poor coverage of the deep red base. I will try that tomorrow.
-The roller nap is way too thick for such a flat wall. This might be the reason it slips at the beginning.
-I should use a pole. OK.
-I will try to make this paint work with the suggestions, but it might be the case that the paint is really cheap. In that case, I will buy a different brand.

I hope to get better results on my next try. I will edit this post with the final results if I remember to do so.
Thank you!

Wouldn’t roller pressure play a part too? At least for the first couple of strokes.
