The Jall Wake-up Clock is wonderful! I bought it for myself, to help my body wake up more gradually, rather than be woken up suddenly. Starting my day with a jolt of adrenaline leaves me feeling wiped out for the rest of the day; and, let’s face it. The year 2020 has been a living nightmare. I couldn’t handle the insomnia and chronic fatigue any longer. We live near a police station, and this year there have been more nearby, nightly disturbances than in previous years. Therefore, more blaring sirens at night. It’s made it hard to fall asleep. Also, difficult to wake up, feeling refreshed. So, I bought this alarm clock, because of its sleep function and wake-up light. I desperately wanted to avoid paying for its much more expensive competitor, priced just over $100. This Jall Clock being less than half that cost, I had to give it a go.I must say, it truly works! The light, so long as it’s not set to one of the colored variants, has such an inviting tone. A yellowish hue that’s reminiscent to a sunrise, but perhaps closer to a flickering candle . . . but without the flickering part. My perception of the color’s tone might have to do with the fact that my bedroom walls are painted a rich, tan color; the light reflecting off that is very relaxing and warm—incredibly easy on the eyes. Which is key, for this sort of alarm clock. Anything too harsh could jar you awake. And the point is to allow your body to wake up gradually. It is fairly bright though, if turned up all the way to level 20. Level 15 is my preference. I set the alarm to begin the light function about 30 minutes before I want my alarm to go off. You can, however, set it anywhere from 10 to 60 minutes prior to when you want the alarm to chime. Often, I’m wide-awake before it ever makes a sound. I absolutely love the Wake-up light function! There are up to eight different alarm sounds to choose from: songbirds, ocean waves & seagulls, splashing creek, typical alarm beep, windchimes, piano & songbirds, slower piano, and FM radio. My two favorites are the songbirds and windchimes. All the recorded sounds are rather nice. They don’t have that cheap, appalling tone to them that some other Sound Machines do. Volume levels go from 1 to 16, with 16 being VERY loud. I set mine to 10, typically. Knowing there are six more clicks I could go up does give me more peace of mind. Say there’s an early appointment I can’t miss. Alarm beep at volume 16 will get me out of bed in a hurry. Most likely, the light function will have woken me up before then, and I’ll turn that sucker off, then leap out of bed, refreshed and ready for the day.This clock’s got a nice sleep function too. There are three sounds to choose from: pouring rain, crickets & campfire, and flowing river. You can set it to remain on for 10 to 120 minutes, with up to 20 brightness levels. I personally prefer level 10, for falling asleep. It gradually fades from whatever level you set it at, to 0 after the timer finishes. My husband loved this feature so much, he asked that I buy a second clock for him. And he’s not typically one to do that sort of thing. I can’t recall a time he’s ever said something to the effect of, “Hey, would you buy one of those for me too?” It’s just not like him. That’s how wonderful this clock is. The longer he’s had it, the less he keeps hitting the snooze button, before finally dragging himself out of bed. He has been falling asleep faster, and has gotten higher quality sleep. The same holds true for me.So far, this clock has been my best purchase of 2020. After several weeks of using it, my sleeplessness and chronic fatigue have diminished greatly. I am one happy customer. For the price, I highly doubt you’ll find a better Wake-up light clock than what Jall offers. That is why I give this clock a resounding Five Star rating.
