These are the technical specifications for the Chene products (I've picked one just to see what the product offers).

They are a California based flooring manufacturer which means they have some of the toughest manufacturing requirements in the USA (both CARB II and Lacey Act compliant). The company has been around since 2003 (opened it's doors in 2004). That's 14 years and counting. That means they SURVIVED the 2008 crash.

The Chene line is a wide planked product (7.5" wide) with a thin wear layer (2mm) and coated in UV acrylic polyurethane that has been infused with Aluminum Oxide. Needless to say these floors will NEVER be refinished because they do not have the wear layer nor the right finish to be refinished.

With a wide plank like this, I would expect you to require "glue assist" if you want nail/staple install. That will increase the cost of install.

I have to say that I'm impressed by the detail set out in the installation instructions. This is the first time I've seen installation instructions recommend NWFA CERTIFIED INSTALLERS. I LIKE that! And it covers Urban Floor's BUTT should anything go wrong. They simply point at the words "recommend NWFA Certified Installer" when a client comes back after a DIY job goes sour, or the "Chuck in a Truck" installer has disappeared.

Nicely written documents. I'm impressed. To ensure you maintain the warranty, I HIGHLY RECOMMEND that you do EVERYTHING they recommend. The word recommend, in the building trades actually means "require". It is a legal thing.

I'm seeing nothing that would raise any red flags. In fact I'm seeing a product that is made in the USA and has great warranties written to ensure a quality installation while supporting NWFA professionals.
