Harry’s Bench.
Fresh off the bench: Aqara U400

Hi, I’m Harry. I review home tech and maker tools by living with them.

By day I program lighting for Broadway shows. At home I wire up my own apartment. So I check the things most reviews skip: does it stay connected, does it work when the internet drops, and is it nice to use on a regular Tuesday?

Aqara U400

I finally replaced my Yale. Here’s how the hands-free unlock holds up, and how it gets along with HomeKit and Home Assistant.

Would I buy it again?Yes. Hands-free unlock is life-changing. →

About me

I’m a lighting programmer. I’ve worked on 10+ Broadway shows, plus fashion week and TV. My job is making complicated gear behave the same way every night.

I started Harry’s Bench because friends kept asking me things like “which lock should I buy?” and “is that printer worth it?” These are the answers I give them, written down.

I buy most of what I review. When a company sends me something, I say so at the top. Some links earn me a small commission, and that never changes the verdict.
