Installed within seconds and does exactly as advertised. Full-time 8 cylinder and increase of over 1mpg in my case, blue light not distracting at all. Onstar unable to provide on board diagnostics due to after-market device plugged into computer interface but I am not a big fan of Onstar any way, rather have the advantages that the Range provides. Very happy with this purchase and would do it again.
