  • Good interim mirrors, good quality

    posted bytulonCZ on 06/06/2018

    Bought this as a backup/interim mirror for my bike after the OEM mirror got broken after 10 years. The price is excellent, 2x-3x lower than standard type-specific replacement mirrors, and frankly, the only reason why to buy this. They work and do... Read more

  • Good build, reasonable resistance

    posted bytulonCZ on 06/06/2018

    Cables for lab stabilized power supplies with crocodile clips on the other end. Each pair of cables is connected except for the ends, which are separated. It's safe and easy to extend the separated length by pulling the cables apart. I've measured... Read more

  • Lower luminous flow, but power-saving and very little heating

    posted bytulonCZ on 07/06/2017

    In my impropru test rig, this LED bulb measured only 0,36VA (U=12V,I=0,03A) and peaked at just 51°C at the LED emmitors (and only 39,4°C at the base board). Measured relative luminous flux was 15% lower than with regular glass 5W5 bulb at the same... Read more

    Impression: Cheap,low power consumption,Excelent temperature management;

    posted bytulonCZ on 07/06/2017

    In my impropru test rig, this LED bulb measured 2,16VA (U=12V,I=0,18A) and peaked 117°C at the base board (but only 105°C at the LED emmitors themselves). Measured relative luminous flux was 145% higher than with regular glass 5W5 bulb at the same... Read more

  • Nice dual/hybrid time display watches, WR50m

    posted bytulonCZ on 11/23/2016

    Pros: - this is not a counterfeit product, but instead an original Chinese manufacturer building their brand; that always signifies higher quality because of responsibility - build quality is very nice, fully comparable to original Timex watches -... Read more

  • Seems to work

    posted bytulonCZ on 11/23/2016

    Pros: - could be operated without batteries, powered by USB cable - after it warms up, it does help against mosquito bites scratching - at least momentarily Cons: - none? Remarks: this device seems to work by warming up the chemicals injected by a... Read more

  • Nice constantly shining clock - if you provide external power supply

    posted bytulonCZ on 11/23/2016

    I needed a clock that constantly shines. This does - if you provide external +5V power supply. You need the "H"/3,5x1,35 power connector. Pros: - constant green backlight - if you make your own USB power cable - you could run it on 3xAAA batteries... Read more

  • I keep one at work

    posted bytulonCZ on 11/23/2016

    Pros: - voltmeter is your basic diagnostic tool, so I need one both at home and secondary at work. This one has a good price, so I keep it at work. - when turned off (on stand-by), it doesn't deplete battery even after months of inactivity - the -... Read more

  • Good survival item

    posted bytulonCZ on 11/23/2016

    Pros: - you cannot beat the price - it could start fires by concentrating direct sunlight! - despite being a fresnel lens, the grooves are not too noticeable and you could read small text with it (as much as the 3x magnification allows) Cons: - it... Read more
