I've used it for one night so far and so far it works good. But my main issue? There is zero directions on how this thing works. And I just can't recommend it on that alone. There's no printed directions. Just a QR code with very little information. I've been trying to find out how to charge this thing and I can't find anything about it. I don't see a charging port or literally ANY information on how to charge it.

First, what I received wasn't the same as what was shown in the instruction video, so some features I don't know what they are. Instructions themselves were very simple, too simple. Then there was no "gentle vibration to easily awaken your body and mind". The first two mornings it vibrated so hard it startled me awake. Now its just an annoyance I turn off in my sleep and doesn't do anything. I've taken it off when I didn't need alarms, left it on to stay on a schedule, no improvement in getting up. The way the band attaches is hard to do up and doesn't stay on. It uses two push tabs, which come undone easily when moving in my sleep or throughout the day.

I have never been so impressed by a product, only to have it stop working after just three weeks. When it worked, it was fantastic. As an alarm, it was flawless. It was also incredibly simple to use, which is refreshing in today’s world where so much technology is overly complicated. I was recommending this watch to my friends, family, and coworkers because I genuinely thought it was a great product. If it had continued working, this would have easily been a 5-star review. Unfortunately, reliability matters most. If a product only lasts three weeks, that’s a 1-star experience in my book.

It says the vibrations intensify but when the alarm goes off I only notice one vibration setting.

Was a heavy sleeper missing calls in the morning and decided to try this out. Day one I woke to all three alarms and gave me the reality check I needed. Works great 100% recommend

Is not as effective as advertised. The band is weird too. Doesn’t give a snug fit either. When I tried to upgrade, per their website’s instructions, they said they can’t do anything because it was bought on Amazon and not directly from histrips. Very disappointing

I’ve always hated getting woken up by my loud phone alarms, so finding this was a god sent. It’s easy to put on and sits very comfortably both throughout the day and when trying to sleep. From my experience so far, the battery life is way longer than they say and very fast and easy to charge. And the alarm itself is makes practically zero noise and works perfectly. I haven’t had to set a phone alarm since I got it, and I haven’t had to wake up with a heart attack from it either. If the first the first burst of vibrations doesn’t wake you up, I envy how deep you can sleep, if the second burst doesn’t, you might be dead. My only complaint is that the instructions could be a lot better. Having to scan a QR code instead of having paper instructions is kinda annoying, and the instructions themselves aren’t very good, you’d unfortunately probably be better off using google’s ai to tell you how to use it. However, it is simple enough to use that the bad instructions don’t bring it down too much.

The vibration is not strong enough to wake you up if you’re really tired and it’s difficult to put on. I bought two of these & my son felt the same way on both points.
