  • Great gadget for geeks.

    posted by Brepta

    Simple, relatively small and primitive to use.Accuracy not tested, but looks usable.Clear plastic case looks great.
    Symbols: u means U, A is A.Waiting for your favorite number is ugly.Will be nice to select/switch display mode by button and use full 4 digits for V and A measurement.
    Microcontroller processor can't be identified, has no label on case.I will try to reprogram it.
  • Great product!

    It's a great clock, with a original wood design. Very tiny, excellent to have near bed. The light it's very powerful and can be seen for the very distance. It's has a dimmer for the like, so when the night comes it reduces its lighting power.The quality is also pretty good.You can use it with batteries or the USB cable.I'm very happy with it.
    none that i can think right now.
    It's a really good product, the price is not the best but it's not bad for its quality. I really recommend it if you want to renovate your old clock.

  • Cool electronic clock

    posted by madmax1981

    It is a cool electronic clock, it look's very nice on the desk. It came packed in bubble foil. It has temperature sensor and it can display the temperature wich is very usefull. It has 4 display modes: only clock, only date, only temperature and alternate. The temperature is not very accurate, but if you have a accurate termometer you can correct the error because the module has that function. Also has the correction function for the clock too.
    This is a cool clock with bright led's.
  • Nice cheap timer relay

    posted by mr22turbo

    Great price! Screwed one open and the electronics on the inside are well made.Its possible for the timer to count down or up to the set time. Timer can be set in seconds, minutes and hours.
    There are different types of timers, check the product number, this one needs AC220V as a power source. Timer has possiblity to hook up a reset and pause switch. The relay can be connected as normally opended as well as normally closed. English manuals can easly be found on the internet through the product number.
    Great product for a great price!
