I Love the look of the clock. I used to be a mechanic in the Navy, I own fast cars and street bikes, I moutain bike and have taken up cycling as another hobby so the gear design of this clock is perfect for my man cave. Not that most of you would care, but that is a big factor of my rating.
Functionality, it tells the time and it tells it quite clearly. Each hash mark is 15 minutes and those are the only ones that really count. I've had it up on my wall for two weeks now and the time is still accurate.
Why you might not like it:
It's loud. It's not a clicking clock, but you can hear the motor turning away. In a quiet room this might be troublesome, but it's in my man cave, I'm watching movies, playing games, and listening to music, so it doesn't bother me.
It's plastic. I wish it was some form of alloy, but it's not. This thing will break if handled too much. Put it on the wall and just forget about it.
You can clearly see the lines where the numbered gear is put together. Upon assembly you have to snap several pieces (4?) of the big gear with the numbers together. Where those pieces meet you can see the line it forms.
If not installed onto the wall completely flat against the wall the big gear will get stuck on one of the pieces behind it. This will burn out the motor if left in the stuck state. Luckily I was still admiring it when I noticed this issue. I reinstalled on my wall and monitored it closely over the next few hours. All good.
So many negatives, but I still love it. Like I said, put it on the wall and forget about it. Looks great in my man cave and it's perfect for my character.
