Well, the COCO Emergency Alert Smartwatch is advertised as the ideal choice for seniors who want peace of mind. Is it really? I've been wearing the BT2-X for about six weeks now, and I've also had the older BT1 model for over a year. Here's the truth: the calling feature is genuinely good, but the voice assistant is so quiet I can't hear it in my living room, let alone out in the garden center.
I'm Eli, by the way. I've logged over 8,000 miles running with various watches strapped to my wrist, and I've spent the last two years testing the ~$17 to ~$40 range to find out which ones don't lie to me. These senior-focused watches aren't for me, but they are for my mom, and I've been setting them up for her and her friends for a while now.

I don't do lab tests. I wear the watch while I'm watering plants at the garden center, I sleep with it on, and I try to pair it with my phone while my dog Murphy tries to sit on my arm. For these, I also did something specific: I handed them to my mom and watched her try to use them. That's the real test. If she can't answer a call or read the text, the watch fails.
I also ran my known 5-mile course with each of them on my other wrist to see if the step count and heart rate were even in the right universe. They're not running watches, so I'm not expecting Garmin-level GPS. I just want to know if the heart rate is within 10 beats of my chest strap.
The COCO BT2-X
The biggest problem with the BT2-X is the voice assistant. It's supposed to be a feature, but the speaker is so quiet I have to hold the watch an inch from my ear to hear it. My mom asked me what it said, and I told her I had no clue. That's a fail for a senior-focused device.
But for the price, the calling feature is the real reason to look at this one. My mom called me from it the other day and I had no idea she wasn't using her phone. She asked if I got a new phone. I told her it's the watch. She didn't believe me. The sound comes through clear on my end, and she says she can hear me fine. That's the whole ballgame for this category.
The text is big. I mean actually big, not "we made the font slightly larger" big. My mom can read the time without her reading glasses, and that's a win. The battery lasted a full day and night of wear and still showed 82% when I plugged it in the next morning. I charge it when I shower, 15 minutes tops, and it's never dropped below 70%.
Pairing it was the usual DaFit app nonsense. The QR code on the watch screen doesn't work. You have to dig through the manual, find the QR code in there, and scan that one. I've done this dance four times now, and it still takes me two tries. Once it's paired, it's fine, but getting there is a test of patience.
The date format shows dd/mm even though my phone is set to mm/dd/yyyy. I'm done caring about that, but it might drive you crazy.
The Audar E2
This one is heavier. I noticed it immediately. The case is bigger and the band is thicker, and after a full day at the garden center, my wrist was feeling it. The stock silicone band makes my wrist sweat something fierce, so I swapped it for one of my scrunchie bands from FTYQUEE and that helped. But you shouldn't have to fix the band on day one.
The fall detection and SOS features feel more intentional on this one. The BT2-X has them, but the Audar E2 has a dedicated SOS button that's easy to find by feel, which matters if someone actually falls and can't look at the screen. I tested the SOS by pressing it and it called my phone right away, no fumbling. That's the feature that justifies the higher price.
The screen is brighter, too. Outside in the sun, I could actually read it, which I did not expect from a watch in this range. WOW. The BT2-X screen washes out a bit when the sun hits it directly.
But here's the thing. The heart rate monitor on the Audar E2 was off by more than I'm comfortable with. On a test run, my chest strap said 158 average, and the watch said 172. That's a 14-beat error. For a senior-focused watch, that's a health data problem, not a small discrepancy.
If someone is using this to monitor their heart rate, that error could send them to the doctor over nothing or make them miss something real.
The app is the same DaFit situation, so the pairing struggle is identical. It took me two hours to get it connected because the app was still holding onto the old watch's Bluetooth connection. I almost threw it across the room.
The COCO BT1
This is the older, cheaper version, and honestly, for ~$25, WOW. It does the main thing: it makes and receives calls, and the text is readable. My mom used this one for a year before I got her the BT2-X, and she never complained about it once.
The problem is the step tracking. I've had this watch silently stop counting my steps after a few weeks. I work in a garden center, I'm walking constantly, and when the watch tells me I've taken 2,000 steps Ultimately, I know it's lying.
The fix is always the same, reset it, and it works for a while, then stops again. I'm done caring about that.
If I can't trust your step count, I can't trust anything you tell me.
The battery on this one degraded faster than the BT2-X. After about three months of daily charging, it started dying at random times. No trauma, no buildup on the contacts, just stopped holding a charge. I've seen this pattern across multiple cheap watches, so it's not unique to this model. It's the single most common complaint I keep seeing in buyer reports.
One buyer I remember, a woman from Florida, said her BT1 died completely after four months. She said she'd buy another one because it was cheap, and that's the mindset you need for these. It may not last a long time, but you get what you get for this price.
Which One Should You Buy?
Choose the COCO BT2-X if you want the best combination of price, calling quality, and battery life, and you're okay with fighting the app once to get it set up. The voice assistant being quiet is annoying, but it's not why you're buying this watch. You're buying it so your mom can call you without digging her phone out of her purse.
Choose the Audar E2 if fall detection and a dedicated SOS button are your top priorities. The heavier build and the heart rate error bother me, but the SOS feature is the most robust I've seen in this price range. If that's the feature that gives you peace of mind, the extra weight is a fair trade.
Skip the COCO BT1 unless you're on a very tight budget and you only care about the calling feature. The step tracking will stop working, and the battery will degrade. It's disposable, but it's ~$25 disposable.
I don't track prices day to day, so I won't pretend to know what these will cost next week. But I've seen the BT2-X dip below ~$30 during sales, and at that price, it's a steal.
My Honest Bottom Line
The COCO BT2-X is the one I'd buy for my mom, and I already did. The calling feature alone is worth the price, and the big text makes it usable for someone who doesn't want to fiddle with a phone. The voice assistant is a gimmick that doesn't work, and the app will test your patience, but the core function, being able to call and be called, works better than anything else at this price.
For ~$36, you get what you get, and what you get here is pretty good.
