Happy Puzzle Company The Amazing Clock Kit - Construct your own colorful real working clock. Educational toy that teaches how clocks work, and doubles as an actual wind-up clock.

There is a look-alike on the market which is a few dollars cheaper but instructions are terrible and pieces did not fit - never worked. For a few dollars more this one comes with detailed clear instructions and the all the pieces fit well. Spend the few dollars and get this model and you will be happier

Great toy that my great grandson loved at first sight. He sat right down and worked on putting it together. He just turned 4. Would recommend.

This is an excellent model for anyone, not just children, to enjoy putting together. Takes maybe 10 minutes to put together, and maybe another 5-10 minutes to get running true and accurate (bell hammer alignment). Will definitely purchase more in the future for gifts. It is a great STEM learning project for kids. Highly recommend buying it.

It was fun to build this with my son. Unfortunately, it doesn't work because the escapement has too much resistance and doesn't put enough energy into the pendulum. The fitment of the pendulum is so poor that I thought the stool was defective. It isn't, the pendulum is just that loose. The crank placement is very poor and interferes with the pendulum too easily. Very disappointing. Also covered in some kind of mineral oil. Gross.

The six year old I bought this for was obsessed with this clock. He took it to show and tell at school and they were all obsessed with it. It broke pretty quickly, mainly because he refused to be without it. It's not sturdy but its a plastic clock.

The clock is a great idea, but the first one I received did not work. I believed it was the spring, but after double checking the gears that came pre-installed straight from the box, I noticed one was placed upside down. I didn't originally touch the gears already on the pegs because I assumed they were placed correctly by the manufacturer. However, after putting the replacement clock together (mostly by memory [it's pretty easy]), I had to take it apart to flip the white gear. A few notes:Be sure to have a magnifying glass handy to view enlarged instructions.Double check even the gears that are placed prior to unpacking.Beware, the ticking is LOUD and fast. The length of the pendulum is adjustable, but it extends further than the base of the clock. I may need to put a small weight on the circle and shorten the length back to a more appropriate height to correct the timing.The green peg/cap on the front tends to fall out easily, but a little glue or tape might help there.The plastic cover also seems a bit fragile when pressure is applied, and I'm concerned it will break. However, with a bit of colored hot glue (maybe with glitter in it for fun) I believe it may actually be a great learning tool.My 4yo certainly enjoyed seeing it come together and work for the first time. I doubt she's ever seen the inner workings of spring-operated gears. With her aptitude for puzzles, and curiosity to take things apart, I am ultimately glad for the purchase... Though I will have to come up with a way to dial down the ticking!

The instructions were a bit muddy on how things went together, and the pictures could be larger to see how things go togetther, It took me a 3 tries to get the clock together. It's also very LOUD, puts my 140 year old mantle clock to shame at how loud the ticking is.It's also very fragile, a slight bump and it's flying apart. Keeps time ok though.

Thanks
