I bought 2 "Family Shield" (from Bunnings) alarms with the model number SD-588H-LL in 2015. The model was SD-588H-LL and the packaging referred to harco.co.nz. I realise this is a slightly different model, but the 588HLL identifier has to be a worry. Both started giving false alarms within a few months. Nothing wrong with the batteries. I took one alarm back and got it exchanged, but the new started giving false alarms a few months later. Gave up and binned them. Distributors & retailers shouldn't be allowed to sell substandard safety product.
No, this product has too many drawbacks.
