Excellent quality tool and extremely reliable. I have dropped mine time and time again and is still in mint condition. However, it is a pity that the frequency range, covered by this product stops at 18KHZ instead of 20KHZ. None the less it is a great tool for recording bass, guitar or keyboard. There are so many little tricks you can use this gadget for. For example in conjunction with a microphone, if you just want a dry signal, or if you only have the space for an amp in your list of plug in's. I think most studios would have radial di's in their catalogue of equipment and it really is my go to di.
