I just exchanged a defective mono Speedy 30 for the Bh. I love the Bh ,but when I put my stuff in it hurt my shoulder. I do have a previous injury, but my petit bucket doesn't seem to bother it. My husband and stepdad both said I should just keep the BH .I really love this bag but my shoulder has been hurting on and off for a year due to carrying an other brand very heavy bags. What should I do? Only one week left to exchange the unused Bh again. How embarrassing.
