I bought it in October 2017, as small guitar interface for iPhone and notebook. I bought also the iRig HD-2.
Simple idea - to have good practicing sound, when on the go.
It did not work with iPhone. I could not stand the huge input compression. So, I checked it with iPad, MacBook Pro, iMac, PC.
The same story everywhere. There is no possibility to play dynamically. Even, if you barely touch the string, there is always huge compression attack (as my wife asked: "why it clicks so loud?").
I can imagine - it can be used, when you play punk, or when you play very overdriven/distorted guitar, with always full gain or guitar volume turned to 10. Exactly the same story was with iRig HD-2. Maybe they use the same cheap preamp for instrument in both devices.
So - to be clear - even, when you turn the GAIN pot to 1, you still have LOUD attack click. Then - if you turn it to 3-4 the signal is already overdriven (even with vintage single coils).
Because of curiosity I bough the "copied" devices from Be company. They sound the same way (I will say perfectly copied, but unfortunately not improved) ;-)
So, basically - I have stored in my drawer since 2017, and never really used.
Reassuming - if you need interface, that you want to use for guitar, and you need inexpensive one for on-the-go practicing - go Apogee, or buy any decent, real USB audio interface (Ident, Presonus, Focusrite offer very good quality instrument preamps with decent price).
(but - you may always say - I am deaf amateur and hear nothing - I will not discuss with that) :-)
