L3+ Antminer, too good to be true?

I know this is a little off-topic, but do any of you have any experiences with antminers? Im thinking of purchasing some of the new Antminer L3+ just for the sake of it.

According to various cryptocurrency profit calculators, this new Antminer L3+ is the way to go if you want to profitize on your minings.

Is it too good to be true?

How was your experience with the previous antminers? I know this new L3+ model is strictly scrypt based.
