Our story
We use products at home before we recommend them.
Terra Hills is about the gear Evan uses around his house, yard and training. He sets it up himself, keeps it in the routine for months and writes once he knows what's good, what's annoying and what has held up.
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.
Who's behind it
Meet the tester

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.
- Ultramarathon & half Ironman finisher

How we test
What happens before a review goes live
The details change with the product, but the basic process doesn't.
-
01
Choose what to test
We look at the models people ask about, compare what's available and decide what to buy.
-
02
Live with it
Products go to work in a real home for weeks or whole seasons, setup headaches and all.
-
03
Compare it with the alternatives
We look at performance, durability, ease of use, price and what else you could buy instead.
-
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.
