Getting my first binder Monday, anything I should be wary of?

Ik the obvious don't wear it for too long or take breather breaks, but is there anything that's not talked abt as often? (I'm a small-chested guy, if that changes anything?) Such as how people don't talk abt a lot of side effects of T and stuff, I'm just hoping to be prepared and be able to take care of it and myself well enough to wear it lasts a good while The binder is from Underworks, which I heard is pretty good overall
