As I expected, in Chinese ..... but silkscreen with component values Assembled, it works. It only acts as a watch. I was interested in how to stopwatch, it can be done. Found the x system to make it a chronometer. Bought back a second kit

The printed board received is different from the one on offer. I hope it is a correct option and the delivered components correspond. It seems that some components are missing and others are extra.

It doesn't match the description. The printed circuit is not as described and does not have all the components to work as described, very disappointed with the product.

I didn't like it the reason is because I'm Spanish and the instructions only came in Chinese and I can't assemble it properly because I don't understand the instructions total my score 0
