It is totally up to you, But I didnt live with it, they tried the same thing to me, (sending the noise suppresor) I never had a good unit , but one or our members skidoonut, like after 10+ unit finally got a good one, whatever your choice is is cool, I just dont like them acting as we should put up with an ok , not perfect, so go away product!!!
Sorry to hear about the sag, now that sounds like a really big problem, make sure they dont give you some duct tape to cure it LOL, Good luck!!!
