Independent reviews · Real home, real seasons, real miles

Reviews written after the novelty wears off.

Pool robots that ran every day for a full swim season. A watch worn for two years. Shoes with 200 miles on them. We live with gear long enough to learn what holds up, what gets annoying and what's worth your money.

Asphalt Driveway Sealing: Why We Waited a Year and What Our $2,000 Project Included

We sealed our 6,000-square-foot Texas driveway for $2,000 after waiting one year. Compare costs, one vs. two coats, drying times, and contractor questions.

Why Terra Hills

We keep using things after the review would normally end

We set products up on a Saturday, work them into the daily routine and keep them there. Some stay for a season. A few have been around for years.

About Evan and the process
  1. 01

    We use it at home

    The pool gets leaves, the kitchen makes dinner, the front door gets answered and the shoes go out on real runs.

  2. 02

    It stays in the routine

    Products live on the real schedule: the robot cleans when the pool needs it, the alarm arms every night, the espresso machine pulls the morning shot. Nothing is staged for a photo.

  3. 03

    We compare what else you could buy

    The score comes down to how well it works, how long it lasts, how annoying it is to use, what it costs and what else you could buy.

  4. 04

    We keep checking in

    If a part wears out, firmware changes or a new model arrives, we come back to the review. The date at the top tells you when.
