Why we exist

Why we wait before writing

Product pages make everything look good. After a while the specs blur together, and it's hard to tell which problems will show up once the return window closes.

So we wait. We use things through real seasons, notice what wears out and write down the details we'd want to know before spending our own money.

Evan Mercer

Founder & Lead Reviewer

Evan builds software for a living and runs Terra Hills from home. Pool cleaners run laps in his backyard, security sensors line the doors and the kitchen counter sees more espresso machines than any one person should own. He's finished an ultramarathon, a half Ironman and dozens of triathlons and half marathons, so he pays close attention to heart-rate zones, recovery scores and whichever running shoe survives his weekly trail mileage. If he reviews something, he has probably lived with it longer than his family would prefer.

What you'll find here

What you can expect from a review

Used where it belongs

Pool gear goes in the pool, kitchen gear makes dinner and running shoes get real miles.

Enough time to find the flaws

We keep products for weeks, months and sometimes years. Durability can't be rushed.

We tell you how long we used something, what happened and why it got its score.

Your questions and projects help us choose what to test next.

How we test

What happens before a review goes live

The details change with the product, but the basic process doesn't.

  1. 01

    Choose what to test

    We look at the models people ask about, compare what's available and decide what to buy.

  2. 02

    Live with it

    Products go to work in a real home for weeks or whole seasons, setup headaches and all.

  3. 03

    Compare it with the alternatives

    We look at performance, durability, ease of use, price and what else you could buy instead.

  4. 04

    Write it, then come back later

    We publish the good and bad, then update the review if something breaks or a new model changes the recommendation.
