While this is definitely a fun gadget to play around with and records video reasonably well, I would not recommend it as a spy cam, there are simply too many lacking features to make it effective for that. However, it does make a pretty neat toy/gadget.

It's nice and lightweight and moves very easily. I found it very easy to connect to the app and set it up by following the instructions on the manual (make sure and press the big 'on/off' button on the app screen to activate the controls if the tank doesn't move at first. When I first connected it, it disconnected, but after a minute seemed to adjust itself and from that point forward I had no issues with connectivity.

The controls do take a little getting used to, but they move very smoothly and easily with a little practice. It can even go down small steps/bumps, but won't go back up over them. One of the reasons it's not very suitable as a spycam is that the movement is quite loud (think toy car noise), so it's not very stealthy. There's also no way to remove the video from the tank. While the pictures showed up on my phone, I couldn't get the video anywhere outside the app or transfer it from my phone (note: This could be due to the mjpeg format, perhaps my LG G3 could not read it without the app), which is a real shame as I got a pretty adorable video of my cats being surprised and curious about the tank.

I do like that the camera is able to be angled up and down, however the camera gets quite blurry when turning, so it really has to be static or moving forward or back to capture good video. It's also lacking sound, another shame, as parking it somewhere to record conversations is pretty much a must for a spy toy.

That being said, it was fun seeing things from my cat's point of view (although not fun seeing how dirty my house is!), but I'd say it's more of an interactive toy with a bonus video feature than a true spy toy.
