Review: SpyX DIY Listener is a toy that teaches as well as entertains. - “Toys” have come a long way since I was knee-high to a grasshopper growing up on the family farms. Today, toys like this one, the SpyX DIY Listener, not only provide the young person with hours of fun, they teach the child some real-world skills. I received this “toy” for free to evaluate and review. STEM toys intrigue me, so I was the first one to play with this one. I spent a few hours assembling, disassembling, and reassembling this listening device. It worked flawlessly every time. It was time to give the secret agent man in my family, my eight-year-old great-grandson, a shot at it. What I like about these STEM toys, they are safe. These are real electronic circuits involved here, but the circuits operate off three AAA batteries. There’s no chance of getting an electrical shock. This “toy” can also promote father-son interaction or mother-son interaction.
Review: Frustrating for 9 year old grandson - This was a Christmas present for my 9 year old grandson. He was excited when he opened it. It was hard to put together (had my help 1st, then his father worked to put it together). My grandson got frustrated & put it aside. Almost a month later, he hasn't mentioned it, let alone played with it. Don't recommend it, waste of money.
