OWill 4 inches Twin Bell Loud Alarm Clock for Heavy Sleepers Battery Operated Retro Alarm Clocks Bedside with Light for Travel Bedrooms Desk（No Battery Included）

The clock arrived this morning, and although I knew it was 4" from base to bells, it seemed smaller than I expected. I should add that I was buying this clock to replace a larger, 6" tall version which we have had for many, many years.I inserted a battery and set the time and the alarm, frankly curious to know just how loud a smaller version of the clock would perform. When the alarm went off, it did so with tremendous gusto. There is no doubt in my mind that this little clock will easily wake the heaviest of sleepers.I was surprised at the amount of noise it made, considering it runs on just one 'AA' battery. (My older clock, which has become unreliable, required 1 type 'C' battery, and I cannot think of any other item I have which requires this type of battery).The controls are straightforward - one control for setting the time and another for setting the alarm. An 'on/off' to turn the alarm on or off, and a small button (also on the back) to illuminate the dial in the darkness of the night.For its size, this small clock makes a hell of a racket, and after all, that's what you want it to do.I'm totally satisfied with the clock, and for the price, you cannot really go wrong. I recommend it without reservation.

Am mostly pretty pleased with this, it's exactly what I wanted, a cheap, effective and nice-looking alarm clock. It is a bit smaller than I expected (but that was 100% my fault - the description did have the size, and it doesn't matter). It keeps good time and makes an awakening noise. My only real reservation is that the controls are a bit hard to see (black on black) and a tiny bit fiddly even once you've worked out which way to turn the alarm on!

I broke my phone and realised I couldn't wake up on time without an alarm so I was missing my lectures. I bought this alarm clock hoping it would help me wake up until my phone got it and it came within 3 days which was amazing. It is perfect for the job! It is about the size of one hand but make no mistake, it's size is no indication of it's sound. You use a dial to set the time for the alarm and when it reaches the set time, the sound is the shrillest I've ever heard and will most definitely wake even a bear in hibernation. It even comes with a little light inside the clock to check the time in the dark which is a cute addition. Hope that's helpful!

A great size which has been working fine in it's first week. Night light is always handy so very happy at the mo.

I like the clock but it isn't reliable, it only worked for a short time and even when I changed the battery it didn't work.

Very disappointing. This clock only works when it feels like it. Constantly stopping and restarting. Unreliable. I have tried new batteries and should not need to use a new battery every two to three days.

Oh I love this little clock, with the loud ringThis clock doesn't tick tock, nice and quiet when you are ready to sleep, when the alarm goes off it's loud, I love it, I need a loud alarmThank you, this clock is a little beautyMy grandchildren love it as the have never seen or heard a clock like this.

It's quite small, which is good because it fits easily on a bedside table. It is silent, apart from when the alarm rings. So altogether it is as described. I wish that the bell was slightly noisier, but then it would all need to be bigger, so I think this is a good compromise on size, convenience and effectiveness.
