Firstly, the box makes the toy feel cheap, on unboxing my first thought was, why does this look like a dead mouse? Pushing that aside we continued to play but noted one of the interchangeable balls had come apart due to a failure in the glued joint. Using the other balls, we continued on, the range of the remote was around 4 meters with a clear path, this toy gave fantastic stimulation and was let down by the asthetics of the packaging and failure of the product. We have contacted bondara about this product and have no doubt they will reach out to resolve this issue.
