Customer Reviews

  • from Weybridge - Surrey Rating:5 stars

    Bought this to replace a temperamental smoke alarm which would go off without warning, despite it only being 5 years old. This detector is superior in many ways and was both easy to install and maintain. Highly recommend it as it offers fantastic performance and value for money.

  • from Bolton Rating:5 stars

    I bought these to replace my old units which were 10 years old. This is a great detector which doesnt give false alarms from cooking etc. This newer version includes a slim push fit base which is far better than the old type. Great price too from Safe Fire Direct.
