At the Venti is basically nothing wrong, he is very quiet (Really so quiet that you could easily sleep next to it) and makes for the price really NEN good job. However, I must say that I would have really liked a more detailed description. I was not sure how to grip handle for connecting and so I came out of a 1,5x3 tube cables. But there is only one 2-wire cable (So no protective conductor). Do not know if that's normal or not for Ventis, in any case one does not need the protective earth conductor. Otherwise, the child's play is to be connected. Easy Strip cable, wires pure, tighten and finish. Since I have however used a 1,5x3 cable, it was difficult to stow the cables so that everything fits in, went with a bit of tweaking as well.
