You see the reading, not just the panic.
A 2.8-inch rotatable color screen shows CO in PPM, gas, smoke, temperature and humidity in real time. Most alarms only speak once — when it's already bad.

safety.
Carbon monoxide has no smell. No color. No warning. It doesn't wake you up — it keeps you asleep. HomeShield Pro watches the air while you can't.

The problem
Your nose is not
a detector.
Carbon monoxide binds to your blood 200× faster than oxygen. Early symptoms — headache, fatigue, confusion — feel exactly like being tired. So people go to bed instead of going outside.
A detector is the only thing in your home that notices before you do. HomeShield Pro doesn't just beep — it shows a live PPM number, so you know whether it's a whisper or an emergency.

Why HomeShield Pro
Four things the
white plastic disc
can't do.
Outages are exactly when CO spikes.
Generators, space heaters, gas stoves for warmth. Power dies, risk climbs. The rechargeable cell keeps it awake for 8 hours after the lights go out — no AA scavenger hunt.
Zero tools. Zero drilling. Zero holes.
Snap it to the magnetic adapter, or plug it straight into the outlet. Renters, dorms, RVs, Airbnbs — installed in under a minute, gone without a trace.
Louder than the alarm that already wakes you.
85dB audible siren plus a red visual strobe. Sound alone fails deep sleepers and anyone hard of hearing. Two channels, one message: get out.

60 seconds.
No drill. No screws. No landlord conversation. Two ways to place it, both reversible.
01
Magnetic adapter
Adhesive puck goes on the wall or ceiling. The detector snaps on and pulls off clean for charging or travel.
02
Direct plug-in
Straight into any standard outlet. Continuous power, rotatable screen angled wherever you actually look.

Straight answers
Ask the hard
questions.
No — and that's why most detectors end up in a drawer. The photoelectric smoke sensor reacts to the dense, slow smoke of a real fire, not fine particles from searing or steam. Keep it 10+ feet from the stove and out of a bathroom's steam path and nuisance trips effectively disappear.
Bedrooms and hallways outside sleeping areas first — that's where CO exposure turns fatal, because you're unconscious for it. Then near fuel-burning appliances: furnace, water heater, gas range, attached garage. Mount at breathing height or above; CO mixes with air rather than sinking.
No. The cell is rechargeable and built in — no 3am low-battery chirp, no drawer of dead 9Vs. Plug-in or magnetic-adapter power keeps it topped up, and if mains power fails it runs roughly 8 hours on backup: the exact window when generators and space heaters push CO risk highest.
The frame is aluminum alloy over an ABS core, not the all-plastic shell this category defaults to. It survives being knocked off a shelf, tossed in a carry-on, or moved between apartments. The 2.8-inch screen rotates so the readout stays upright whichever way it's mounted.
Orders leave the warehouse within 24 hours on business days, with tracking emailed the moment the label prints. You get 30 days — plug it in, live with it, test it. If it isn't earning its outlet, send it back for a full refund. No interrogation.
Treat it as a layer, not a demolition. Hardwired interconnected alarms are required by code in many homes and should stay. HomeShield Pro adds what they don't give you: a live CO number, gas detection, temperature and humidity, a visual strobe, and coverage in the rooms your hardwired system skipped.

Jul 28Furnace was leaking and I had no idea
Bought it on a whim. Second week it started reading 40 PPM in the basement. HVAC guy found a cracked heat exchanger. I'd been sleeping directly above it for two winters.

Aug 2Finally one that doesn't look like a hospital
The metal edge is the giveaway — feels like a device, not a plastic disc. Guests think it's a smart home gadget. It sits on the hallway wall and I don't mind looking at it.
★★★★★Ted W.✓ Verified buyer
Jul 19Tested it. It is genuinely loud.
Ran the test button from two rooms away with the door shut. Heard it clearly. My old alarm you had to be standing under. The red flash is the part that would actually get me up.

Aug 6Renting, so the magnet was the whole point
Landlord won't let me drill anything. Adapter went up in a minute, detector snaps on and off. Takes it with me when the lease ends and leaves nothing behind.
★★★★★Greg M.✓ Verified buyer
Jul 11Bought three. One per floor.
Basement, hallway, guest room. Being able to glance at an actual PPM number instead of waiting for a beep changed how I think about the furnace entirely.

Aug 9Goes in the van every weekend
Camper van with a propane heater. This lives on the shelf above the bed now. Small enough that packing it isn't a decision I have to make.
★★★★★Denise R.✓ Verified buyer
Jul 30No 3am chirp. That alone.
Every detector I've owned decided to announce a low battery at 3:12am. This one charges itself. Zero night interruptions since it went up.

Aug 4Four stars, one gripe
Works exactly as advertised and the screen is sharp. I'd like a dimmer night mode for a bedroom — the display is bright in a pitch-dark room. Everything else is excellent.

Jul 22Sent one to my mother
She's 74 with a gas stove and a detector older than my car. Plugged it in herself, no instructions needed. Texted me a photo of the screen. That's the whole review.

Aug 11Cooking doesn't set it off
This was my worry. Wok, high heat, plenty of smoke. Nothing. Old alarm would have gone off twice. Kept it well clear of the range like the guide says and it's been silent.
★★★★★Rachel V.✓ Verified buyer
Jul 15Humidity reading was an unexpected win
Came for CO, stayed for the humidity number. Found out the spare room was sitting near 70%. Got a dehumidifier in there before it became a mold problem.
★★★★★Kenji T.✓ Verified buyer
Aug 13Power cut, it stayed on
Storm knocked out the block for six hours. Screen never went dark. Neighbors were running a generator in a closed garage and I was very glad to be watching a live number.

Last thing
You'll never
know the night
it worked.
That's the point. A detector that never goes off is a detector doing its job. HomeShield Pro just makes sure you can see it working — every hour of every day.

HomeShield Pro is a supplementary safety device. It is not a substitute for hardwired, interconnected alarms where required by local building code, nor for professional inspection of fuel-burning appliances. Test monthly. If an alarm sounds, leave the building and call emergency services from outside.
