Bluetooth doesn't work. My car asks for me to enter a pin on the device but there is no way in the Fiio software to do that. So I'm probably going to have to wait for a firmware update. They shipped this product unfinished and it's annoying. The only reason I got this was for the Bluetooth, otherwise it's just a normal X1. Apparently there's some different internals, but you won't hear any difference. UI is exactly the same. The ONLY reason to get this instead of an original X1 is Bluetooth and that doesn't even work right. Frustrating.

This got me playing the guitar really quickly. I was surprised at how fast I got into the basics. It won't teach you sheet music, tabs or make you as good as a professional guitarist, but it is a very valuable supplement when starting out. Even if you're intermediate it will still help a lot on improving techniques such as hammer-ons, pull-offs, slides, bends, etc. It's very useful in learning songs too. It's much quicker and easier than looking at tabs.
