Hi All I recently bought a Prius 2015 (S model) which sadly does not come with a cruise control. But I noticed that you can buy Cruise control separately and install it. First of all, is it safe to do so? Second, I noticed that you can buy Toyota original cruise control unit or buy copied Chinese version. I wonder if anyone has used these copied version and had any problem with them or not, because they are much cheaper than the original one. I have bought this one from BINGWFPT (AliExpress item number 1005005220489106), and I wonder if any one has any experience using this one. Best Regards
