Review: Muy bueno mi esposo tiene problemas de audición este si lo escucha
Review: Two alarms, very nice brightness adjustment for those of us who like our bedrooms dark and are irritated by the various lights that electronics provide. More important, the alarm can be set to a variety of volumes from quite soft to ear-piercingly loud. There are a variety of sounds, from the stock beeper to a bugle and others in between. Its an alarm clock and it does what it is supposed to do. The manufacturer thought it out though, and included the "nice to haves" that make it a really good buy. In my case, I even got a retroactive refund because an export fee was reduced after I paid for the thing. The refund was small and desertcart probably spent more processing it than I ever collected - so a nice aside there on a good business practice...

### ⭐⭐⭐⭐⭐ Review
*by M***T on 1 December 2025*

I was looking for a loud alarm clock, as I am a heavy sleeper. The alarm clock on my phone wasn't cutting it anymore. I looked at many different alarm clocks, and nothing quite stuck out like this one. I thought I would give it a try and for the price point figured it would be a decent product. Instructions were clear and easy to read and set up. The multiple alarms is nice for those days I don't want to wake up at the same time. The variety of alarm sounds are loud, my personal favorite is the rooster. It wakes me up and gets me out of bed. Thoroughly impressed with this alarm clock.
