I got the iRig2 from Bajaao at a good price. For casual and weekend musicians like me that want an efficient interface that doesn't take a hit on my pocket. I use it with GarageBand iOS and my work is sorted so easily.
The delivery was quick with proper secure packaging.
iRig 2 and GarageBand iOS work like a charm. I use it for recording YouTube bass covers of various songs. There is absolutely no latency. It's simple plug-and-play. Make sure to register your product immediately on the IK Multimedia website though their support is lame and bogus.
Keep in mind that if you are connecting the iRig 2 to your iPhone or iPad, use the official lightning to 3.5mm connector from Apple. It's a bit costly but without that nothing will work. if you are trying to use any cheap knockoffs of that official connector, then you won't be able to record the line input that is guitar or bass guitar.
Below is a link to the bass cover in which I used iRig2 to record bass with GarageBand. That should give you an idea of sound output. It is nothing high-fi but smooth enough and easy enough to get the job done.
