I just got off the phone with Kidde, because I have MANY to be replaced. All were on the recall list. She said the new units all come with FedEx return shipping tags. She said that I will need to call FedEx and have them arrange a pick-up, since you cannot drop them off at a FedEx drop off locacation "since they are FLAMMABLE"!!!! I told her that I had never heard if a flammable fire extinguisher, and did she possibly mean "pressurized"? After dead silence on the phone, she finally said "I guess". So, don't expect to play/train with your old extinguishers, and be careful with them, as they might be flammable, lol.
I find it hard to believe it will be $$ effective to repair them, but maybe they want them out of circulation to reduce their liability? I have a FEDEX guy in my office almost every day, so I guess this should be easy.
And...flammable. Now, a flammable fire extinguisher would be a really good reason to recall them.
