They are of typical surface quality, which for me simply means average durability (some would argue that). The bases aren't that great and even though I was told they are sintered I'm pretty sure they are extruded, or of a really low density. A lot of people called them buttery but I find them to be mid-stiff, maybe a bit on the softer side but definitely not the softest ski out there. The tip profile is super low and it is fairly easy to catch a tip on taps or crazy presses.
With that said they have a shorter than average radius making them fun to carve and rip through trees. They are lighter than most skis, but not super lightweight and as long as you keep up on edge maintenance they shouldn't be a problem. For $140 (new?) I'd say go for it, you shouldn't regret it.
