Like I said about the icing....I am so happy to be able to buy this online. It is a family favorite, it also was shipped on time and arrived early. Definitely going to buy again.

Bought this because i didnt want to pay 100 plus for the alternative. Found it to be extremely reliable. Very crisp sound with little to no background noise. Before i bought it other reviews stated it seemed a bit cheap. I disagree, though i do find it to be a bit bulky for it's function. I did drop and break it once, but it  was completely my fault. After breaking it, i contacted customer service, and it was replaced very rapidly. The company's website was easy to navigate, and rather amusing.

I love this stuff.  It sweetens without affecting the blood glucose levels.  Now if I could only figure out how to make tequila I would be set.  Just kidding.
