  • 3-Segment LED Display

    posted by poteroa

    A very good product for voltage info of two or more batteries connected. Quite simple design, fits allmost anywhere.Welding and parts quite good, works straight from the package.
    Nice package
    Easy to use if you know how to google the pinout, cheap. The loss of the schematic and pinout guide is a big minus.
  • Good looking, and functional clock

    - Stylish design
    - Comes with AC adapter
    - Can also use backup batteries (not required)
    - Large, easy to read numbers
    - Can cycle time forward and backwards when adjusting alarm settings (handy for people that need to wake up at different times each day)
    - Loud alarm (near impossible to ignore!)
    - Temperature and date features
    - Clock can be turned off and on (using button on the back) without loss of time settings
    - Instructions provided in both Chinese and English
    A few tiny flaws, but otherwise a great product. Stylish, simple to use, and functional.
  • Great DC Voltmeter/Ammeter

    posted by icefire21

    - works right out of the box, no external shunt required;- two separate adjustment screws on the pcb. Voltmeter and Ammeter can be separately adjusted/calibrated if readings are inaccurate.- easy to hook up- relatively accurate (once adjusted, accuracy is ok..)
    Excellent price/benefit ratio. If you bought a volt-/ammeter and a separate external shunt it would normally cost about 50% more, so it's pretty much a good bargain. Perfect for home DIY projects (I used it for a DIY car battery charger)
    Excellent price/benefit ratio. Just great :)
  • Excellent buy

    Excellent watch, a lot of attention when it is triggered. Accurate marking the date and time, highly visual fashion. For the fans, combines with any outfit and any situation. It has an extremely comfortable rubber strap, and is very discreet when it no turn on the LEDs.
    It is not interesting for normal daily use, because the battery consumption is high, forcing replacements more constant than in other types of clock.
    It is beautiful, easy to use and comfortable. It is an excellent buy.
  • Great clock, short cord

    Easy to use, just plug it in.Instructions in English and fairly simple.Includes mounting tape.Nice clear display.Three brightness levels.Has battery installed for backup.
    This really surprised me, when I plugged it in, the time was correct. It is nice having a button just for brightness, that is all the button does. Too bad the label didn't say brightness instead of set2. Other than that, the voltage and temperature are on a rotating display with the time, unless you program them off. Even with the voltage turned off, you can still display it by pushing button set1. The clock also features a mirror mode where you can view it correctly in a reflection. Besides that it is 12 or 24 hour mode.
    This clock has a bright disply that stays on as long as it is connected to 12 ( actually 7 to 30 ) volts. It is easy to read and shows the inside temperature. Temperature probe is 6 centimeters long.
