Every product is bought with our own money, tested 30 days in our Winnipeg lab. Only survivors go to our Amazon shops. No paid reviews. Ever. Top-tier brands do US+CA — we do too.

We buy every product retail. No freebies. No brand influence. Receipts posted. If we didn't pay, we don't review.
Winnipeg lab: thermal, endurance, material check. We log temps, times, failures. Only data, no opinions.
Top brands run US + CA. We do too. CA list 2D1ZONUD8DPIC and US list 3667V1X6CWDKY both with checkedlab-20 via OneLink. One site, two stores.
