I put in 7 claims back in October, 2 weeks ago Fed Ex dropped off 2, they were both the same, so I boxed up 1 return. A few days later, 2 more show up, both the same, so I boxed up 1 return. The third delivery was the same. I called the Kidde hotline, told them I was going to have to return 3 and was told to go ahead and keep the 3 wrong ones. Okay, so that was a few weeks back, I've sent back the bad ones and now everything has stopped, WTF? I appreciate the freebies but really would like to replace the larger extinguishers too. Guess I'll wait and see what happens.
