Beware before using that air fryer.  There’s a chance some models sold at Best Buy could catch fire.  The retail giant is recalling three types of Insignia air fryers after nearly 70 complaints about items burning or melting.  That includes two injuries.  The models are either all plastic or contain some plastic and come in black or stainless-steel finish.  They were sold in store or online dating back to the end of 2018.  Owners can return the device for a refund or credit.
