Review: Good quality - I haven't use it as yet but it does come with baytery and screws. Nice and small, qualify product.
Review: Simple to install - I found instructions a bit complicated and I do not know how it actually works. It has a test button; but will not know how good it is until it actually goes off. Hopefully never in anger. THe one I had previously goes off through some cooking times, but this one never has. If it actually works as described, it will be marvellous. It does state that it will cut out "false Alarms".

## Questions & Answers

**Q: What are actual dimensions of alarm rather than packaging please**
A: 4cms deep and 9cms in diameter.

**Q: Could this alarm be fitted to the ceiling using an adhesive pad?**
A: I don’t see why not, using a good quality pad eg 3m. The fixing is a back plate so you should be able to replace the battery without disturbing the adhesive pad. Note other models are on the market which include adhesive pads

**Q: Is this good for using in cars ? as one of my family members keeps smoking in it and i want to use this**
A: Hello, thank you for your question. Domestic smoke alarms such as this one are not designed to detect cigarette smoke. To sound an alarm (and not give false alarms) they require a higher concentration of smoke than would come from a cigarette being smoked, but there may be other products on the market that are specifically designed for that purpose.

**Q: I’ve only had this alarm a few weeks but it keeps going off randomly. There is no smoke it’s nowhere near a kitchen any ideas?**
A: You may need to change the battery if it wasn’t new when you installed it. Otherwise try placing the detector elsewhere. If that doesn’t fix it send it back as faulty.

I found instructions a bit complicated and I do not know how it actually works. It has a test button; but will not know how good it is until it actually goes off. Hopefully never in anger.

### ⭐⭐⭐⭐ Effective BUT with reservation
*by G***T on 27 October 2023*

We bought this as the apartment we rented in Madrid didn’t supply. I cannot fault the size and ease of handling but similarly to other reviews the battery supplied lasted 10 minutes after installation. Thankfully I had brought a replacement with me. So either review the quality of battery supplied (it was still in its cellophane wrapping) or sell without one.
