I'd just go with a known name brand. A little cost savings isn't worth it on safety equipment

(Searched x-sense ul listed smoke detector and the PDF above now comes on page two)
The Amazon listing pretty clearly documents the lack of UL marks on these devices.
Good luck!

Edit: After some more digging, I have found that these are, in fact, Intertek ETL listed to comply with the UL 217 standard. Intertek is an NRTL (Nationally Recognized Testing Laboratory).

Edit: As pointed out below by The_Love_Spud, the ETL listings are for a different model (SD07 not SC07). So, yeah, the models in this deal do not appear to be listed or certified by an NRTL. Stay away!
Kudos to X-Sense for the SEO required to bury results such as the following from the city of Marietta, Georgia's fire department:

According to the user manual on the X-Sense website, these conform to UL standards for both smoke (UL 217:2020 9th Edition) and CO (UL 2034:2017 4th Edition). However, it doesn't actually state that they are UL listed or certified.

They initially made their entry into the market with "smart" functionality as a market differentiator, which, initially, just meant that the individual smoke detectors could be synced together, so that they would all sound an alarm if any single detector went off, and later added room assignment for each detector (so that if smoke was detected in, say, the kitchen, they would all sound an alarm saying that smoke was detected in the kitchen, etc). Great functionality for larger homes, where you can't hear the alarm going off on one side of the house if you happen to be on the other.
I don't know precisely when they entered the market, but my dad had the ones with the room assignment function for some time, since their mid-sized (~5,000 sqft) single-story house had pretty well sound-insulated rooms, and those worked perfectly. He passed away in '23, and he had those for several years, so they've been around for a while, at least. I installed that same type in my mom's house last year, and there have been no issues thus far.
Just to note, neither of the ones I have had experience with were powered by a button cell, so I have no clue as to whether this specific model offers the same quality, but the company itself is definitely not a no-name brand.
