Review on Experience Technological Brilliance with Tunai Firefly 2018 (Gold) by John Surabhi

I used these in my 2008 BMW 135i, 2006 Toyota Prius, 2009 BMW 135i and my dad's 2016 BMW 228 and there are currently two of these things. This is a complete game changer and I cannot recommend it more highly. Excellent sound quality and no more fiddling with iPhone adapter cables. The only slightly annoying thing is that about 1-2 times out of 10 it doesn't connect automatically and you have to go into the phone's Bluetooth settings. However, it connects quickly when using fdo and I'm not sure if it's a phone issue or a Tunai issue. Overall I am very satisfied with this product. Also, I strongly recommend not using the newer version with built-in microphone for calls. I tried it and I really hated it. Terrible sound because the Aux and USB ports were on the center console. Stick with it and you won't be disappointed
