Ex Input:
I don't like this product at all.  Much tastier and cheaper to just use hot water and a packet of hot chocolate mix from Nestle or Swiss Miss.

Ex Output:

Ex Input:
I really like the frozen Corn Muffin Tops, but the mix resulted in a dryer product. I used the paper muffin liners and I think these might have added to the dryness.

Ex Input:
Perfect tool for any musicians trying to make recording much easier at an affordable price. Easy to open plastic case, medium sized, durable (People have said that the plastic body feels cheap and feels easy to break but it's not true. The Icicle's plastic body feels durable and won't break if you're not clumsy with it or break it on purpose). I only wished that the "Gain Control" had numbers or indications of levels so I can turn the knob to the correct position for recording and remember it instead of guessing all the time. Sound quality is FLAWLESS! No buzzing noises or anything picked up really...just nice crispy sound recorded through a good quality microphone is all I hear. I hear no difference in it with an Icicle or a Mixer
