Last year, my mom bought my son the VReader, but he was only three, and I thought the system was a bit advanced for him then. I just bought MobiGo for him on December 28, 2011. On the following morning, I noticed that the speakers blared, and it was difficult to understand what the characters said. About an hour later, the sound was completely gone. I'm a teacher, and I choose the educational toys for my son carefully. I have bought vtech toys in years past for my nephew, and I had no trouble out of the VReader. The one day this toy worked, I felt that this was the perfect gift for my 4-year-old who is beginning to read. He has asked for a popular game system, but I refuse to buy it. I did not want him to get hooked on video games that for the most part, have no educational merit. I felt MobiGo was a sound compromise. Had the sound not gone out on it, I would definitely recommend this toy to others. I do hope the issue gets resolved quickly. My son enjoyed it thoroughly while it worked.
