Any experience with this bit?

I just bought a new bit for my gelding and I was wondering if you guys have any experience with it?
He's super broke and really good under saddle so he doesn't really need anything harsh so I thought this would be a good choice.

It's a Myler Dee Snaffle with Copper Inlay.
