I purchased this as a gift for my ourdoorsy 4-yr-old nephew.  I was uncertain he would be able to make a call but purchased it b/c it was called "easy."  While I don't know if a Mallard would actually respond to it (as he blew it indoors ALL DAY on Christmas), I can truly say it is an EASY call.

B: positive
C: neutral
D: negative
E: very negative
Answer: A: very positive
