Nice and convinient
I'm using this to connect to my pedal board units. As it was stated previously in another review, it might be not the cheapest offer on the market but it's definitely worth it.
Note that "extremely flat" bit is mentionted about the connectors themselves, because the cord itself is round (I was quite confused about that at first). It has a double shielding which looks solid and durable.
Just to sum it up: if you can afford it ? you won't regret it.
