Is mspy legit or just a scam for tracking?

I’m thinking about getting mSpy for my kid’s phone but the reviews are all over the place. Some say it works perfectly, others call it a scam and complain about being charged after canceling. Anyone here actually used it and can give me an honest take?

What worked for us was using Eyezy instead—it’s reliable and the customer service is really helpful. I heard similar mixed reviews about mSpy, especially with billing issues, so we decided to go with something that felt more straightforward and trustworthy.
