Are you looking for a spy camera that’s so small that you can hide it in your gym water bottle? Then you should definitely consider the Mia water bottle spy camera. It looks so small that it’s easy to dismiss as just a tiny black dot on your bottle top. However, it has the power to capture high-quality video and audio footage that’s good enough to stand in court. You can take it with you on the road while you’re running and capture the different routes you took so you can view them later on your smartphone.
