Review: great alarm! - works well. easy to set up, it is indeed extra loud. different colors to use as a display and you can also change the brightness! has military and standard time
Review: Surprisingly Impressed - modern, bright, attractive, loud -- almost perfect - I bought this clock for my daughter (5) as a backup alarm. For the money, I didn't expect much. I am really pleased with this purchase. Pros: - Display is Aesthetically Pleasing The display is big and bright. I really like the clock font - it's very attractive and neat. - Display is Customizable The ability to change the color on the display really allows the clock to adapt to the room. This is something I didn't really expect to be as important as it feels now. - Nightlight on Snooze Button = Nice Touch Having the top snooze button act as a night light is a really nice touch. It's distracting to me and I turn it off, but for young children, this could be a plus. The night light is also customizable - it can be set as several different colors or turned off. - Alarm Volume is Adjustable For hard sleepers, the highest alarm wake setting is very loud. I don't imagine that anyone would sleep through this highest setting. There are four levels, so somewhere between the very light alarm noise to this one should provide an option for everyone. Cons: (There aren't many - I'm almost nitpicking) - Setting the Clock Is a Bit Unintuitive Overall, the buttons on the back and the top of the device to set the clock feel a SLIGHT bit unintuitive, but this isn't a criticism of this clock alone. I bought a similar clock from IKEA this week and it works the exact same way. I'm used to holding the 'Clock' or 'Alarm' button and then pressing the "+" and "-" button to set the clock. The new clocks have you hold down the alarm buttons for a few seconds. It's easy to pick up, but just might take some getting used to. - Alarm Can't Be Set for Certain Weekdays One great thing about a phone or a voice assistant is that you can set an alarm for Mon-Fri or whenever your work days are. This clock has two alarms, but you'll need to turn them on/off depending on the day. I'm not used to having to remember on Friday night to turn off my alarm to sleep in on Saturday. Summary: I really like this clock. It's visually appealing, has a loud alarm, is very customizable and a great option for the money. The nitpicks about not being able to set different alarms for days of the week or the interface being a bit unintuitive are small. Buying a clock *did* make me appreciate the features that my smartphone has -- things that you just don't get with a basic alarm clock. But for those who don't want their phone in the bedroom or if you don't want your child to have a smartphone in the room (or they're too young to have one), this really works as a nice alternative. I bought the clock for my daughter, but I'm strongly considering this for my home office as a persistent visual clock that restricts me from having to pick up my phone or check my wrist.

### ⭐⭐⭐⭐⭐ Makes waking up a little more fun.
*by A***W on May 14, 2026*

I love this clock. It is super simple to set up and use. The numbers are big and bright for those bleary mornings. The alarm is loud, I only have to set it on volume 2 so this thing will wake the neighbors up if you are a hard to rouse type. The best part are the many different colors you can set the numbers to be. There are even rainbow changing colors. I change the color everyday just because. Keep in mind it has a place for batteries so that it remembers it's place in case outage. I keep forgetting to put them in. Make waking up a little more fun. Great deal for the price.
