SignMission Square Root Wall Clock Math Teacher Calculator New Gift

The only set back was my cat heard the second hand and kept attacking the clock because he thought there was something alive. We moved the clock so Shadow can not reach it unless he gets creative.

Extremely well packaged! Time is accurate. Feels sturdy and well constructed. Couldn’t be more pleased. Ordered a second as a gift

Mechanical Engineering absolutely loves it for his office.Keeps good time, clear face so you can read from a distance.A tad noisy if in a small spaceGreat gift for my nerdy husband he loves it.

I bought this in 2013. When I received it, all three hands were not fastened securely - just hanging loose. I took the cover off too fasten them on the spindle. Even though I got them on, it didn't work that well. The AA battery compartment is such a tight fit, that either between inserting the battery or removing it misplaced something internal to the mechanism. Flash-forward to 2020 with time to look at this closely. I have watched several videos on repairing clock mechanisms, so I have taken it apart to find the problem. I am finding that the gears do not fit that snug together - the magnet gear (which links with sec, min, & hour gears) does not even sit properly. I am still struggling to get the hands to stay on! Since I spent money on this, I am going to buy a better clock mechanism to replace the cheap one - though it would be easier to buy a clock at a dollar store, print and paste a face plate with the square roots to use at school.

A perfect gift for your friends who are math nerds.

I am a retired math teacher, so LOVE this clock! I am still educating!!

Perfect birthday present for my math geek autistic son.

I bought this for my classroom. I teach math. I thought it would be a fun thing to have on the wall. I posted a pic on Facebook and everyone is loving it. I got it two days ago, it's kind of small, not fancy, kind of cheap, but it looks cool, and should work just fine. But I'm glad I bought it for the price. For similar purposes, I would recommend it.
