STAY AWAY FROM BUDDY G anything!!! They sell defective products and then will not honor their warranty. I had the defective chip and the owner refused to reimburse me after I paid to have it sent back.
"We discovered the problem in early April and promptly replaced all products with good microcontroller with all our authorized dealers including Amazon. The defective chip had a marking of 1135A (batch number made in 35th week of 2011). This was the reason for bad rating on Amazon that customer is quoting.? -written by owner Parmod Gandhi Buddy Microphones Corp on 22 June 2013.

"I am afraid we can not respond quickly to your support needs. The reason is that we are self financed tiny company geared towards research on man-machine-interface. I am also adjunct system scientist at Carnegie Mellon University. This is an honorary position they gave me based on my research. We have zero marketing and zero sales staff. We spend 95% of our time working on improving speech recognition. I am telling you all this because you know before purchase what kind of support you can expect. I do not want to mislead you into thinking that we have large staff just for support. We do not."
