Out of 6 Orca alarms 4 have developed faults and cause false alarms within the first 2-3 years. We have been woken middle of night 3 times, and our neighbours have rung us while we were on holiday saying our smoke alarm has been going off all afternoon. Total waste of money - how we have to invest in replacements (will not be this brand) for them all as we don’t trust them.
No, this product has too many drawbacks.
