Eh. I still have my cheap plastic one I bought when I moved out of home.

But I also purchased a Mason Pearson. This was only because I want to extend my wash days, and for that boar bristles were recommended. The brush itself is just OK in my opinion, as the bristles don't go all the way through my hair, so it's difficult to use it to put my hair up for example. It also can't be used for any heat styling.

So, I have my old plastic one I use for heat styling and putting my hair up, but I use the Mason Pearson for brushing it at night to spread the oils.
