Anyone using bra for pumping?

Hi, I am about to go back to work and will start pumping much more (right now I mostly nurse). I will be able to pump in my own office, but I won't have more than 20-30 minutes each time, so it makes sense for me to pump both breasts at the same time. Which I really don't like doing right now because when I hold the pump up to both breasts I can't do anything on the side and it's so boring. So I am wondering if it would be worth getting one of those weird bras that hold the pump in place. Has anyone tried them? And do they actually work properly? Thanks!
