### ⭐⭐⭐⭐⭐ Sometimes you just need to be patient to get the results that last long!! Or.. read the manual :)
*by R***Y on July 29, 2021*

I'm amazed by this atomic clock, but.. it wasn't "love" at first sight :P Ok, I really liked the slick look and huge numbers right away, but... I couldn't make it work properly - waited like two days to match with the right time and was unable to connect with the outside sensor for few days until... I've read the manual (better later than never :D ) and some awesome advices from the reviews! Since then I have no issues with the the clock at all!!Pros:- big display with big digits showing the time on it- slick and modern look- can be hanged or placed on your desk (has a stand attached)- shows accurate time and temperature!! (compared with other sensors and there was maybe 1 degree difference few times)- other info like date or mentioned temperatures (I got it with inside and outside sensor) also very visible and easily readable- placed outside even in the sun, still works well and with no issues (kept it outside for few days in about 100-110 F heat)- no wires, need just 2 AA batteries for the clock + 2 AA batteries for the sensorCons:- had to wait a little bit until it matched with the right time (read the manual! there is a button to help you out with this :) )- was unable to establish the connection with the outdoor sensor for few days until I've read the manual and the response to one of the Q&As - read the Advices part below when I quoted it)- wish there would be a night light but it's not that big problem at all (it would be just nice addition)Advices:- read the manual and follow it!! :)- to get the outdoor temperature working "take the batteries out of both the clock and the sensor. Make sure you have fresh batteries. Leave off for at least 60 minutes [I left for about 30min or so]...(the manual says 5..bit I found 60 to be much more effective). Put the batteries in your remote then into your clock. Restart as normal and it should read everything." If this still doesn't work revert the procedure with batteries - putt the batteries first to your clock then in the remote!!- wanna hang it without making holes? use the velcro!! (not included of course, but the unit is so lightweight so you don't need too much of it - available anywhere in the stores)- lost the connection? read the manual! :D It says exactly which button is to trigger the connection without waiting until the night!- F switched to C by itself (it happened to me!) - read the manual, instructions which button should you use are right there!!Overall - excellent unit to use indoor and outdoor!! Read the manual and keep your batteries fresh and the clock will work just perfect!!

### ⭐⭐⭐⭐⭐ So far So Good
*by K***P on January 1, 2023*

I bought this UMEXUS Digital Wall clock to replace my La Crosse Technology WT-8002U Digital Wall Clock which conked out after 6 years.This UMEXUS Digital Wall clock met my requirements because it includes the date, day of the week, and temperature as well as the time. The Good-sized numbers are also easy to read., this digital wall clock has a nice colour.The design makes it easy to fit this wall clock into any type of decor, and at just over 9 inches, it’s a great size for any wall in the home.I chose this UMEXUS Digital Wall clock chiefly because I was looking for a non-atomic clock…… I am hoping that I made a good choice.I have had this clock for a short while now but to date, it has served me in good stead.However, time will tell about its durability.

### ⭐⭐⭐⭐ Good clock with some flaws.
*by H***. on October 21, 2020*

Numbers are large and thick, easily viewed from a distance. The month and date is reversed from the usual position, the date is placed before the month which can cause confusion until you get used to it. Biggest flaw is that it runs fast, about one minute per month. If accurate time is important to you, you must reset time every month.
