DD chest clip broke on her Radian. So ofcourse we haven't been using it. I ordered another one from SKJP. I ordered it last week to ship UPS. Well I still haven't received it. So I called today. She says it shipped USPS on the 17th. Even though I chose UPS. She says that locktites can only be shipped one way and that is USPS. She said that they were working to fix the options on the website. Then she proceeds to tell me that DD can use the carseat without a chest clip that it has been test and is fine. Can it really be okay?? All I can think of is 1) it's not a 5pt harness then and 2) In the even of an accident she could come out of the seat. So is it okay to use it without the Chest clip? Has anyone else ever heard this before. I questioned her and she kept telling me it was fine. Right now we have just been lugging seats between the vehicles when we have too. It's her 2nd seat that's broke.
