Hands free breast pump

Ma

Has anyone used any of these, I’d love to hear good or bad experiences? I’ll be working this breastfeeding journey and my boss suggested a hands free breast pump to me to help keep things running smooth at work (I work at a pet salon with only a total of 3 workers; 2 groomers and 1 bather (me)). I don’t want to jump the gun and buy one just yet
