I have both the Vinion and the Prunion, both in the 250 versions. Very good. The Prunion is a bit more tiring compared to the Vinion, but it is stronger and opens the blade more.

Fast, lightweight, and balanced. It cuts everything like they don't exist. I use it in the vineyard and in the olive grove. For me, at 47 years old, it feels like playing. I get a week's worth of work done in a day. My 80-year-old father also uses it comfortably. The support from the dealership is excellent. I highly recommend it and stay away from some Chinese ones that are not what you see and promise. I've been fooled.

Very fast and powerful, up to 4 inches of wood perfectly balanced center of gravity exactly in the middle of the scissors battery lasts 2 days the fastest blade change from small to large with a small finger movement through the photocell many screen settings very detailed cut due to the thin fixed blade very good blade quality that does not wear out always sharp very convenient case that you place above the knee and quickly take out something that helps when you are on a tree.

I have had it for a month now and it is the fastest scissors I have ever used! Very powerful, it cuts large sections and after 2 days of work, it still has 25% battery. I recommend it to everyone.
