Set of strings with three large are protected by a kind of plastic film 20 €. Not small!
Balance after a month or two I find myself with three strings rotten (ground if mi) and 3 as new, without a hint of oxidation. Result in a chord the sound is awful all the same. It was well worth the extra € 20 the game ..

A notice says that they are easily two years. Ropes protected I do not know, but the fine must not exaggerate in 1-2 months they are all black!

Against the ropes by the agreement are almost instantly and have a good sound right away, I was surprised.

I will not go down with this choice, the idea is good but way too expensive.
