Quick build and extremely good documentation with two small exceptions. There are no clear instructions on how to set the clock and there was a problem with the device working after the build which was corrected by replacing the power supply (not provided in the kit). I worked with the seller to get this information. It would have been easier had this "warning" been in the documentation.
But, overall, it's an attractive looking device, fun to build, and fun to use.

It is most likely a USB power supply problem. I sent an email with helpful instructions. Guess you did not get it. I am still here to help. I've been doing this for over 10 years and sold over 1000 kits and going strong. You don't do that without good customer service.
It is just under 2" in diameter, so looking at the pictures you will realize the parts are very tiny. Fortunately the LED heat tolerance seems to be forgiving to not the steadiest of solderers. Would be nice if the LED part info was listed as I had lost some and need to source some replacements (not their fault, my clumsiness) If you are unsure of your soldering skills and want to make sure you get one completed, maybe buy two so you have spare LEDs at the ready..
The documentation is brief, beside the missing LED part number, the microcontroller does not have an apparent orientation notch, so to match with the board: if you rotate the pcb so the chip pad is to the right and the hole for the hook is to the left, the text on the microcontrollerchip would be right-side up.
For someone who wants to experience SMC soldering this is a excellent introduction with quick results and will make a fine semi-home-made gift for a friend or loved one. I'm sure as I get more accustomed to such a small scale I'll improve my skills.
To be honest, this is the second clock kit I purchased. I fried the first one with my ham-handed soldering skills. After reviewing a few how-to website instructions on soldering and purchasing some new solder and flux, my handiwork gained some compliments from some more tech-inclined friends. The clock functioned right away, as advertised. I'm now incorporating the finished kit into a somewhat ornate desk clock, and plan to share pictures online.
I'm planning to incorporate this clock into a steampunk idea I have. I've assembled it, and it took much less time than I'd expected. Unfortunately, only the seconds-counter seems to work. I strongly suspect it's my sloppy soldering that is the cause, and I'm preparing now to clean up my work. In any case, If I can't make this one work, I'll buy another because the seller was very accommodating and sent me the color LEDs I wanted. (Hence the high scores for shipping and communication.) Documentation is so-so: the tinyurl website was extremely helpful, but the printed address was a bit illegible because underlining it obscured the "q" and made it look like an "a".
Anyway once my little project is complete, I'll post photos somewhere and give kudos to Apple Mountain.
I have not build this unit yet din't have the time to.but i buy for to build.when i do it will be nice.i have other from onther type of kits that i did not built yet but will get to them since i moved over 1 year ago in the basement got clean it will take time to do these kits.since this is small i will do this soon.i tend to buy these and will build them.but when i have the chance.your kits.are very nice and i do like electronics.i will buy more but the money is short.so i will buy a little at a time.i do have power source for any kits.thanks albert.
