Lightning Transactions is the solution to bitcoin's problem, high fees and transaction time - the reason why bitcoin isn't used everywere so far.
But not for long since LT is going live in a few months. Today, you can test it yourself and learn every little dirty detail about it.
This is going to skyrocket bitcoin to the moon.

First test payment was done only for the second try and since then I can't send any payment... OK I know that this is just a test environment. Anyway, the first payment was really fast and it was easy to pay thanks to the provided instructions. I hope that this will go live soon, bitcoin really needs something to speed up the small transactions. I know that LN is not decentralized, but I think most of the average people won't care about centralization or decentralization if it's only about small payments
