3 reviews for Helsinki Smoke and Fire Alarm | 1 Year Battery Operated, Thermally Enhanced Loud Optical Smoke Detector With LED Indicator

  1. Noreen O’Leary

    Arrived today very neat units. Purchased a set of 4. Alarm very loud. Delighted with product, perfect for my requirements.

  2. jjen

    Compact and ideal for my needs

    The Mydome smoke alarm is much smaller than the images lead you to believe, and it arrives in a neat white plastic box with transparent box that can be re-purposed.

    The reason I’m giving it 4 stars not 5 is the non-replaceable battery. While a quoted 10 yr life span is still very good there’s still e-waste to deal with in a decade. Can’t complain about that too much though as I did buy it!

    The alarm is being used to monitor my 3D printer, the supplied mounting plate allowing easy fitting and removal inside my printing enclosure. I would recommend this for anyone else with a similar requirement.

  3. Kindle customer

    Nice and small. OK thus far. Mounted in loft. No false alarms yet. Nice and compact. Shame there’s no off switch unless you keep the tiny removable magnet.
