Perfect for my deaf wife

I originally had the nightstand wired version and lost the buzzer. Decided to try this portable version since I loved the old alarm clock and always wanted to have it on vacation and during trip, so this seemed like the perfect compromise.

Its vibration is just as strong as the wired version for me with one small caveat, it all depends on the batteries. After 3 weeks of usage with the original batteries, it wasn't waking me up and I feared another review's mention of it dying after a month was true. I switched the alarm batteries to some Duracells and instantly had a better alarm than even when I first tried it. Hoping these last longer than the originals.

The batteries completely make the difference and you might find yourself running through a couple if them if you use it like me.

Otherwise, the beep function is great and loud. The snooze button is convenient and easy to use as a light. The clock and alarm times are easy to set and check with the screen popped out. Only drawback to be honest is that it's a lot easier to turn off than the wired version when you really want to go back to sleep although I've had issues in that regard with the wired version anyways.

Also didn't think the clip would be so convenient but it strangely is. I just clip it to my shorts or pillow and it always keeps it on me. Nice since the wired buzzer used to fall off the bed a lot with satin sheets.

This is a very good phone and works well . The vibration in very strong and definite wakes me in the morning. It is easy to operate and I really like the battery check feature.

I am very familiar with and like Sonic Alert products so I chose their travel alarm clock when I needed one. It was a good choice although I wish a couple of things were different. This round alarm clock comes with a nice zip around carry bag. It has a tough ribbon with a clip on it to attach it to a pillow case or wherever you set it. That's a good idea so it doesn't get lost or drop out of bed when you're asleep.

This unit takes two AA batteries and one AAA one which are included. The smaller battery is for the light on the display and the others are for the alarm. Setting the time and alarm are very simple. No instructions needed. You can choose to wake up by a buzzing/alarm sound, a strong vibration, or both. I am hearing impaired and can't even hear the alarm but I sure can feel the vibration! It's very strong. I love that this clock allows me to infinitely hit the snooze button. I hate when an alarm gives me just one or two chances then stops alerting me to wake up. I usually just fall back to sleep. This one goes until you manually turn the clock off.

All that is great and it works wonderfully. It work me up several times with a vibration that I could not ignore. But there are a couple of things that I wish were different about this clock. For one, there is no indicator that the batteries are getting low. They just say that, when the alarm or vibration are weak, to change the batteries. That makes me nervous. If the batteries die, I won't wake up in time.

Also, the light that illuminates the time is just a little orange one that points toward the numbers. It is not back light. I don't really care much about that but it seems that the numbers should be lit up by default but, of course, that takes battery power.

Otherwise though. this keeps time well, shakes me awake with a very strong vibration, and is portable for travel or to use anywhere that an outlet isn't available. I used it when I slept on the vouch the other night. I put it next to my head clipped to the pillow and it did its thing. I was worried it wouldn't but it came through perfectly. I trust Sonic Alert and have two of their plug in clocks that are wonderful for someone who needs a shaker or a very loud alarm. I will just change the batteries when I sense the vibration is not as strong as usual. Maybe I will get some rechargeable ones and charge them each time I use the clock so I know they are fresh. Either way, this works for me and I am happy to have it. My Fitbit was my alarm but it only vibrates once then stops and I often fell back to sleep.

I lost most of my hearing after a bout of meningitis and can't hear regular alarms. I've been using Sonic Alert alarms ever since, but this is my first travel alarm. Like the bedside alarm clocks, it also has a wide alarm volume range as well as a vibrator. If the beeping proves too jarring for you, just set it to vibrate and put it under your pillow. Works beautifully and allows me to remain independent.
