+xYou will see the same traffic in SD (there are screenshots all over the internet how that looks) what you see in SK. What expectations exactly do you want to verify?
You wrote the point: 25 EUR for a year, just spend that few minutes of flying time equivalent and problem is solved...
This is all fine, just like the workarounds you're pointing at (screenshots to be checked on the internet). You may do as you wish, but I personally prefer to check the real thing by myself, like while flying modifying settings on my tablet and observing the result, without having to rely on promises ("you will see the same traffic ...").
Adam, you're missing the point about the price. Paying for a service or a product is fine as long as quality and cost are related, paying for a hope (i.e. a disappointing product) is not, no matter what the ratio is.
