Oh God...
This forum was dominated by someone with a Konecto problem a while back and all sorts of opinions were thrown out on both sides.
Konecto is a decent floor.
But my favorite vinyl plank floor is Karndean. That stuff is awesome! As far a designability, it's unmatched... borders, liners, waterjet-cut patterns, feature strips, design strips... it's the bomb.
That and it's waterproof. Not warer resistant... waterproof. And the glue is also basically waterproof after a 48 hour cure time. Karndean's K91 adhesive is a "private label" of a well-respected adhesive also known as Taylor 2091.
And durable? I took a plank of the VG5 the other day and tossed it out in the warehouse, drove the forklift back and forth over it a few times and then whacked it with a sledgehammer as a demo for a customer. The sledgehammer left a slight indention. And that's got the midgrade 0.5 mm wear layer.
There's an even sturdier 0.7 mm line.
There aren't many floors where you can say, "See this little crescent indentation that you don't even notice unless you bend over and squint at it? That's where I whacked it with a sledgehammer."
The stuff is marine rated for use on cruise ship decks with direct exposure to salt water and is warranteed for general exterior use (though not warranteed against fading in direct sunlight) as long as you use epoxy to adhere it.
And that's my two cents.
