The stuff is great.
Here’s a yuuuge range of quality/price out there.
The ones I use have a complete backing on them, it goes directly over the subfloor (wood, concrete, whatever).
IMO the thicker the better. What I currently use is I think 8mm.
For your own house (as opposed to rental properties etc) I’d highly recommend you get planks that have a “wood grain” texture to them, AND, importantly, are beveled between the planks (“beveled edges”).
The texture and beveling go a long way towards a realistic look and feel. The light hits it differently, and it just looks and feels much better.
Also 8mm thickness at least.
There are also different scratch resistances, what I have is “titanium coated,” idk if that’s just a gimmick or not, but I can tell you that after many years now my home floor looks 100% perfect. Literally not a scratch.
Finally, the good stuff is 100% waterproof. Like, you could literally use it at the bottom of a pool.
These floors are NOTHING like the Pergos of 10 years ago.
