I bought this only for a clock, so I can’t comment on its other features. Great clock, solidly built! Easy to set. Numbers are big enough that I can see them from across the room without my glasses, but not so huge that it makes my apartment look like a bus terminal! At first, I was turned off by the idea of having no buttons on the clock and instead needing the included remote, but I my mind quickly changed. It is really nice sitting back in a chair and with the push of one button choosing a different color or adjusting the brightness. There really are enough colors to complement any decor. The orangy-gold is a nice home color. The brightness goes from off to dim to what I call “laser” bright that could probably still be seen in direct sunlight. I find the second-dimmest setting the best. Would be nice to have a backup battery to keep the time if power goes out, but it only takes seconds to reset the time.

There are so many different LED clocks that you can get lost comparing them all. After getting a couple that didn’t quite fit what I wanted, I landed on this one. I wanted - Time Sync (atomic clock was unreliable, NTP as well…I’ve used bluetooth time sync in the past, and it’s reliable and easy); Seconds; Timer; Counter/Stopwatch; Military Time….secondary desires were day, date, temperature. In the end, this one gave me the must haves. I found I just couldn’t get everything. *Set up is easy. *Remote -Very nice remote (not cheap at all) -Makes it easy to use (I didn’t download the app). I want to manually start a timer, stopwatch, counter (difference between stopwatch and counter is stopwatch has milliseconds and goes past 59min, 59sec). The remote lets me quickly start, stop or reset any of those. It does Tabata / EMOM which give intervals as well as customizing intervals. I’m not that structured with workouts, so start/stop manually works find for me. *Numbers are big, and brightness settings give a wide level of choices. It’s not in a room where it would be too bright for me so I leave it at the brightest setting. The 11 different colors also gives a lot of choice. I don’t need all of them, but appreciate the options. *Chime is a nice feature as it reminds me that I probably need a break. *Power Adapter is supplied. *Bluetooth Speaker: sweet to have this work as a speaker for my phone. But, the volume isn’t very high and the quality is poor. But unique feature. *Hanging Hardware: A little more elaborate than most with the metal L Brackets for the clock side. This is nice. All in all, this really works for me. Cons *Chime: configurable only through app? *Power cable is permanently attached to the clock. USB at both ends (or power plug and USB) would have been better. Given all the other quality design thoughts, I’m surprised about this decision. *Remote Batteries aren’t included. *No buttons on the clock itself to control it. *Timer setting needs to be set each time you use it. *No backup battery. *Hanging Hardware: The location on the sides is too low. I wanted to hang the clock from the middle, so I attached a wire to each side. Becauseof the low location, the clock leans forward. Double stick tape does fix this.

As a clocknit runs fast. The difference isn't much when using timer functions but ifnyoubkeeonas clock non wall primarily every month it ends up about 45 seconds ahead. This lead to having to adjust clock every few months. The multiple functions it has and the ability to change its colors is appreciated. But would time being the main function?I wish I would have chosen something else. It really drives me insane. When my clocks are not in sync.

Disconnects Bluetooth if your phone goes into sleep mode - if you go to adjust settings it resets the countdown / etc timers. When it disconnects it announces lose of Bluetooth - which is annoying. Looks great - but not usable !!!!!

I purchased this to use for a business event and it worked great as a countdown clock! The clock was easy to use and I especially loved the bluetooth accessibility to manage the clock from anywhere in the room. The display was easy to see. The appearance and size matched the description. I didn't need to worry about battery life as it was plugged in during use. I will be using again!

PROS: The clock is very accurate! I have been out of town for 8 days. When I left, the clock was 1/2 second ahead. Now, 8 days later, it's only ONE second ahead. That's not bad considering that the typical LCD watch goes off ±1/2 second per DAY. I use the Emerald Time App on my iPhone to determine clock accuracy, but there are other apps that will do the same thing. PROS: Multiple Colors to chose from including orange! CONS: The Countdown Timer, Countup Timer & Stopwatch are all limited to 59m 59s. I sometimes like to go beyond 1 hour :/ Would I recommend this? YES. A very accurate clock with a second display, as long as you can tolerate the limitations on the timers.

I really like how this clock can be controlled via both the app and the remote to adjust between a regular clock and a countdown clock. It serves a lot of purposes depending on the workout I’m having. The changing colors is a nice bonus and it really adds to my space with clear and precise time. It’s bright enough that I can easily see it from across the garage.
