📦 truststeadfast.com — "Haven" 4-in-1 Detector
Ordered on February 19th after seeing a Facebook ad. The site looked professional and the "80,000 reviews" gave me confidence. It's now April 17th — two months later — and I have received nothing. My order tracking link goes to a dead page. Their support email (support@truststeadfast.com) has bounced every time I've sent it. I paid $79 by credit card and have contacted my payment provider to review my options. Very disappointing experience.

I actually did receive the device after about 5 weeks (expected 7–10 days per their site). The packaging was entirely in Chinese with a small English sticker applied on top. There is no UL or ETL certification mark anywhere on the unit or packaging. When I plugged it in, the display came on but simply shows "000" constantly — it does not appear to update. The product is clearly not what was advertised. When I requested a return, I was told to ship it to a Chinese address at my own cost. I refused. No refund issued.

I'm a retired firefighter and I should have known better. I saw the ad claiming real-time PPM display and thought it was a great gift for my daughter's new apartment. The "80,000+ 5-star reviews" made me trust it. I've now done my research — those reviews cannot be found on any traceable review platform. The website's trust score is 11 out of 100. The domain was only 33 days old when I first bought from it. I never received my order. I strongly recommend checking trust scores before purchasing any CO detector online.

Bought two units — one for my home and one for my elderly mother. Paid $158 total. After 6 weeks of silence and a tracking number that never updated beyond "label created," I reached out. Got one automated response pointing me to a FAQ page, then nothing. I raised a dispute through my payment provider and received a resolution after 30 days. I would strongly recommend verifying any seller's trust score and certification claims before purchasing a life-safety device online.

Received the product after 4 weeks (advertised as 7–10 days). The unit arrived in plain bubble wrap with no branded packaging. The device does turn on and shows a digital display but I have no way to verify whether the readings are accurate since there is no certification and no documentation. The manual is a single folded sheet in small print. The "4-in-1" claims CO, gas, smoke, and "VOC" detection — none of these are individually verifiable. I don't trust my family's safety to an uncertified device from a 33-day-old website. I've purchased a GuardAir Pro as a replacement.
📦 havensafetyco.com — "Haven Pro"
Different site but same product name — "Haven Pro." Ordered March 3rd. No delivery. No tracking update after "label created." Two emails sent, both unanswered. Chargeback filed with Visa. I can now see this site has similar trust score issues as truststeadfast.com. These appear to be the same operation running under multiple domains.
📦 GuardAir Pro — Official Site
Bought the GuardAir Pro after reading reviews here that warned me off truststeadfast.com. Arrived in 4 days, proper branded packaging with UL and ETL certification labels clearly visible on the box. The real-time PPM display works exactly as described — shows live readings from 0 PPM continuously, not just when alarming. Set it up in 10 minutes. Already detected a small gas build-up near my stove that I wouldn't have known about otherwise. Customer support answered my pre-purchase question within a few hours. Very pleased.
📦 Kidde KN-COEG-3 — Amazon
Good, reliable unit from an established brand. UL certified — verified this on the UL database. Does what it says. My only gripe is that the display only shows PPM during an alarm — the rest of the time the screen is blank, which makes you wonder if it's working. After researching I understand this is normal for most Kidde models. It alarmed correctly when I tested it with a CO test kit. Reliable, just not as advanced as the GuardAir Pro for continuous monitoring.
📦 GuardAir Pro — Official Site
I'm an HVAC technician and I know what to look for in a CO detector. The GuardAir Pro has both UL and ETL certification — I checked both databases before ordering. The real-time display is accurate; I cross-referenced it against a calibrated industrial meter I use professionally and the readings matched within acceptable tolerance. Build quality is solid, not cheap plastic. The sensor is a proper electrochemical cell type, not the cheaper semiconductor sensors used in many discount units. This is a legitimate product.
📦 First Alert CO615 — Home Depot
Bought from Home Depot after seeing the Haven ad and deciding to do research first. First Alert is a well-known brand and I was comfortable with the legitimacy. The display only comes on during an alarm though — something the packaging doesn't make super clear. Works fine as a basic alarm but if you want to passively monitor your home's CO levels you'll need a different unit. For basic protection it's a solid budget buy from a trusted retailer.

Ordered three units — one for each floor of my home. Paid over $200. Tracking never updated. After 5 weeks I found this site and realised what had happened. I contacted my payment provider regarding all three charges and am working through the resolution process. The most concerning part is that I genuinely believed my family was protected during those 5 weeks — which is why certification and verified reviews matter so much for life-safety devices.
📦 truststeadfast.com — "Haven" 4-in-1 Detector
Classic dropship scam. The website was built on Shopify, the product images are lifted from a Chinese manufacturer's AliExpress listing, and the "reviews" are fabricated. I work in e-commerce and recognised the patterns immediately after purchase — unfortunately too late. Domain registered about 5 weeks before I ordered. Their Shopify store ID is visible in the page source. Ordered March 1st, nothing arrived. I contacted my payment provider and the matter was resolved in my favour. I'd encourage anyone to check independent trust scores before purchasing from an unfamiliar site.
📦 safeairhome.net — "AirGuard Plus"
Received a device but the certification labels look printed rather than embossed. Packaging is generic. Reaching out to support to verify before I post a full review. Will update once I've tested it more thoroughly.
📦 truststeadfast.com — "Haven" 4-in-1 Detector
Received the product but experience was mixed — the device works as a basic alarm but the real-time display doesn't appear to update as frequently as described. Awaiting editorial review.
📦 GuardAir Pro — Official Site
After seeing the Haven ads everywhere, I did my research and landed here. Ordered GuardAir Pro instead. Excellent experience. Dispatched next day, arrived in 3 days, packaging is professional and the certification marks are genuine — I looked up both the UL and ETL numbers on their respective official databases. The device displays PPM readings continuously which is hugely reassuring. Had a small gas leak near my water heater two days after installing and the unit flagged it at 12 PPM — long before it would have triggered a standard 70 PPM alarm. Brilliant bit of kit.
