My speculation is on the future longevity of warranty not what happening now ...
I currently getting easy warranty and they checking purchase via account records and that seems the norm to what I seen heard and read ...
Pittsburgh line is dirt cheap procure and lot of markup and a less professional aimed marketing .
Tool sourcing and shipping costs isn't what HF calculated when started the ICON campaign thus room for markup becomes difficult without out pricing the brand to consumer base and it the markup that keeps easy warranty viable business.
Other issue is aiming to Pro users means warranty volume can become quite a burden (Myself and many pro tool users are cherry picking ICON for price to early warranty gain potential) .
I purchased Kabo and high-five ratcheting products as good usable tools and I know warranty useful on these tools when used daily, from experience I expected 5 to 7 years of easy warranty be enough get more than my moneys worth for daily pro use .
I be really surprised if they still doing easy warranty on ICON a decade down the road or that if are the replacement tool will be of quality/design match original purchased tool, hopefully they are

but I wouldn't be buying them if you not using them enough to get some warranty return in early years .
Only got look at apex, tektons predecessor, Napa and other stores brands to see what happened to the tool sourcing, lifetime warranty hassles and brand demise to get some idea of possible warranty outcome potential in the long haul ...
Hopefully HF does better with ICON but experience tells me to never assume easy lifetime warranty will last a lifetime lol ...
