It's the Arkam Beard Straightener Brush. I love it to pieces so far. It takes a long while to cool down after use, which is annoying since I travel a lot and have to pack it away constantly, but other than that it's the bomb! Here's a link to it if you're interested:

I've used the Arkam Ionic Beard Straightener for a little over a year and it works well and is only $30. The only "issue" I have with it is when you first turn it on, the temperature gauge climbs quickly, but the brush isn't heating up as quickly as the temp gauge indicates. Just give it a couple minutes and it will get up to temp. Otherwise it works great.
Hey bro, I have a similar beard like yours including the weird wavy kink right under my chin. I fixed my beard mainly by just keeping it fairly neat and trimmed, especially on the neck, but, my brother I have a secret weapon: https://www.amazon.com/Beard-brush-straightener-men-straightening-comb/dp/B07Q5C9645
This thing goes to 450 degrees and straightens the fuck out of my curly ass beard hair. Some beard oil and 5 minutes of brushing and my beard is straight and neat. It honestly works wonders. I don't travel anywhere without it anymore. There are cheaper versions as well that I started with before upgrading which also worked well so don't feel like you gotta splurge on the higher end brushes.

I heat to 300 degrees and slowly brush out and the down until it is styled the way I like it.
I have the smaller version of this heated brush. Very happy with it. (Smaller size looks out of stock currently)
I use a beard straightener when I'm running late in the morning. It does a decent job taming the beard, and takes less than a minute.

Works great, ignore the tards that downvoted me they are just jealous my beard is huge.
