LinCare provides me with my husbands oxygen equipment This past year they changed the tubing they purchase from Salterlabs. I have contacted Salterlabs and complained. This tubing can cost someone their life. I check it 5 and 6 times a day, get up in the middle of the night to check for kinks It is weak and cheap. Are they waiting for a death or law suite, I am sending the tubing to the product safty commission.
