They do something outright fraudulent on their site.
On their site a product's description says it "features a 5 year warranty". But in the specifications it says the product has a "3-year limited" warranty.
Their site lets us post questions about products that everyone else can see (and answer), so I posted a question about the warranty. The question got posted on the site the same day I asked it, BUT RONA MANIPULATED IT TO SAY THAT THE QUESTION WAS 9 MONTHS OLD. The only explanation for that is them deliberately deceiving us by presenting false information.
Businesses that deliberately present false information to sell their products deserve to fail. I'm never considering them ever again.
