OMG I HATE my BB!! It was excruciating!! It had me in tears it was so painful on my upper back! Also I had trouble getting bub out of it.
I got a HAB about 2 weeks ago and I have had no trouble with it. Didn't take too long to work it out and it is so supportive of my back. I wear it so often
Also if I know I am going to use it when I go somewhere I put it on before I get into the car then I just have to put bub in when I get her out of the car.

Good luck
