    Externally, the performance of the goods is qualitative. I did not try the case. Instruction in english.

  23. J***s


  24. V***V

    Great! Sensors work, checked on the exhaust auto-triggered immediately. What is interesting, it is necessary to check on the cold, then the catalyst warms up and does not catch. The signal, of course, is brutal-as it is written. As i understand, in standby mode only the green led winks rarely, the screen does not burn and does not show anything. But if co is detected, numbers appear. Rode 3 weeks to peter, delivery in the end iml.

  25. B***v

    Came quickly, checked, everything works

  26. V***k

    The order was delivered to kiev in 15 days. Remarkably fast (second time) due to the correctly selected postal service. The item is not damaged, packed in your own box. The description corresponds. Marginalizes the green light and yells when you press the alarm button. Two years ago here already bought one, which was installed in the cottage. Successfully guards. Excellent quality. Thank you very much.

  27. M***i

    Batteries run out of power quite fast imho

  28. P***p

    To the exhaust pipe brought, the signal is triggered, it works.

  29. M***o

    The goods came quickly. On carbon monoxide did not check. The sound on the device is loud, the red diode test lamp is bright. One does not suit, the scoreboard is poorly visible from different sides. The control green diode lamp blinks dim, in daylight almost not visible. Overall price-quality.

  30. E***o


  31. L***o

    Delivery fast. the sensor did not check how to check add feedback.

  32. V***a

    Came in the box. Inserted batteries. The sensor squealed and the scoreboard shows zeros. Clicking repeats the process. Check the mixture, sign off.

  33. A***k

    Fast shipping. The goods are well packed.

  34. K***k

    Performance did not check, externally corresponds to the description. Seller recommend.

  71. V***v

    All in full accordance with the product description, best recommendations!

  72. S***v

    The product works, only did not notice in the standby mode of marginalization with a green led. The probe just waits, do not display the numbers, do not flash the leds but at the same time, if bring to the exhaust pipe, pass the metering, the scoreboard shows gradually dropping concentration, up to 500 and the device starts to squeak very nasty. In general, everything works. Attach to the ceiling, not to the floor. This device is co2, not co (gas is heavier than air and accumulates from below). Otherwise, the whole, working.

  73. S***v

    Everything came to integrity and safety. Alarm worker.
