Good looking smoke alarm

Pros

inconpicuous. we have enough hardware on our ceiling as it is.
Don't have to remember to change batery at daylight saving time. Lasts longer. Ours were installed 2018. Now 2021

Cons

Dust or small insect can cause it to go off. Recommend vaccuming every 6 months.

Recommend it?

Maybe, it depends on what you're after.

no expiry date on unit

Pros

small and unobtrusive

Cons

Expiry date not embedded on fire alarm but printed on tag which is removed on install. Expiry dates of smoke alarms must be recorded on Tenancy Agreements. Furthermore these units are advertised as long lif but some have failed within 18 months will not be purchasing anymore of there over priced units when a more reliable unit can be purchased for half price.
Will not be purchasing any more and will advise all my contacts.

Recommend it?

No, this product has too many drawbacks.

Reliability of the batteries questionable

Pros

Small and inconspicuous and easy to install

Cons

I purchased 9 of these Cavius 10yr units and installed in rental properties and holiday home about 2 years ago. Three units have since failed. 1 gave occasional false alarms and was replaced same brand and fine after that. Two more recently have had battery failures and had to be replaced. Starting to loose confidence they will last the distance.

Recommend it?

No, this product has too many drawbacks.

Small, loud, but only somewhat reliable.

Pros

It's small size makes it inconspicuous. This can be good in rental properties where some tenants with a habit of burning toast take down alarms as a 'precaution' against false alarms - they don't know it is an alarm, so keep it on the ceiling. Their good looks make it great for high spec homes. Alarm is loud and piercing - great for waking you up, not so great for testing!

Cons

The unfamiliar size and shape can lead to some false accusations that the landlord hasn't provided alarms. The side test button is unexpected, so some tenants don't test these themselves (I recommend landlords check alarms every 6 months or less). If you don't have it properly clipped into the bracket the alarm won't work, so make sure you test it after installation. Cavius did a recall of some batches, if one fails check if it was from this run. They do fail before 10 years, I've had several in both my own home and rentals that haven't lasted more than 3 years before beeping 'flat'.

Recommend it?

Maybe, it depends on what you're after.

Small and great quality

Pros

- Small and aesthetically appealing
- battery lasts for 10 odd years
- doesn’t give false positives like many of the cheaper ones
- easy to install

Cons

- pricey, but I figured with cost of batteries over 10 years for a cheaper one it evens out

Recommend it?

Yes, I recommend this product.

Cons

Costs more but worth it.
