Bulfyss USB Rechargeable Digital Alarm Clock, Date, Temperature, Backlight LCD Display Smart Clock with 3 Alarms Bedroom Table Desk (Black)

Great battery backup works more than expected 3 months. And great display as shown in the pictures.

Works perfectly.

It is a very good clock. It blinked red light of charging signal after Frist use of 70 days. Best clock for senior citizens as it glows in dark in night. Though it is 20 seconds fast after 75 days

Perfect bedside companion to keep track of time. About some of its pro are : * The battery after a month of use with Alarm calls everyday is so far fine. I trust it to run alright, looking at other qualities of this clock. * The timer has been quite accurate with the UTC clock. After a month of use, maybe it got displaced by 15 secs or so, which is good in my opinion. I have a Citizen Eco drive & even that looses a couple of seconds in this period. * The time display is big & clear. Bwst part is the feeble glow at night, which is not at all discomforting but sufficient enough to see time in dark & then again, if you need to see it clearly, just press the Snooze for the brighter glow. * The 3 modes of weekdays & if you want to skip Saturday & Sunday from Alarm run is good & well thought out. It does help at times when I wish to keep your regular alarm, but don't want it to run on Sundays or such. Else, you can make it run all 7 days too, based on the setting there. * The main reason, I wanted such a simple clock was for bedside/ tableside time access. A dedicated clock. Mobile is just so much of things & I wanted a simpler dedicated clock. Most importantly, the Alarm on the clock. I have had moments, when for a reason or two, the mobile alarm won't ring, maybe for some Software issue or whatever. That is no more the case here. I have been using this as an Alarm everyday for about a month now & its perfect for my needs. Alarm sounds loud. I get up every morning with this, with the sound. Happy with the purchase & use after a month.

Good features overall, but the alarm volume is extremely low. Not suitable for heavy sleepers. Disappointing and misleading as an alarm watch.

Has multiple alaram options

Accuracy is slow by some milliseconds. I tried to set the time at which exact with my mobile time. And I started to see the time change is slowly getting delayed in this device as days progresses. Which means like after 2 weeks I see this device is now 1 minute delay with my mobile time. The rest of the features are fine. Good visible backlit on dark room. Battery is performing good (hasn't recharged for two months till purchase. FYI, I have done full charge before start using this device). Alarm not bad if you keep device like 1 to 3 meters from you. Device is very light weight. Since due to accuracy issue, I am giving 4 of 5.

Overall satisfactory but not worth the price tag. Here are some of the design flaws. 1.To stop the alarm (one has to search for the alarm button on the back side ) - The button on the top is for snooze. 2.Snooze time is always 5 minutes. ( not configurable ) 3. The clock mode is always 0-11 not 24HR format. ( not changable ) 4.There is a weekday/weekend mode button which is pretty useless 5. the AM/PM toggle does not exist - so if you want to change from 2 AM to 2 PM , you have to press the setting button ( up/down) 12 times . 6. Date format is Month/Day - For the date format in India , it is confusing. ( eg: 1/8 is Jan 8th , not 1st of August ) 6. For the same design with just enough functionalities, you get other options for less than half the price Pros Battery looks like heavy capacity - 1200mAh ( should last for a white) Rest of the features are as advertised and works well.
