No dislikes of this product. ### ⭐⭐⭐ Check return and waranty options. *by M***. on Reviewed in the United Kingdom on 7 February 2020* Battery should last 10 years. It did not. ### ⭐⭐⭐⭐ Secure - Mains Powered *by M***M on Reviewed in the United Kingdom on 19 September 2019* I think (off the top of my head) that every house needs a couple of fire heads fitted now and new houses mains powered ones. Regardless, having fire heads fitted is a 'Good thing.'So I had a couple in use but when a couple came up for review I figured more the merrier and thus I have this.Not pretty - which is similar to most fire detecting heads of course - but fortunately after a short period of time you simply don't see the pimple hanging from your ceiling. Humans ability to filter is quite remarkable.To fit of course you need a mains power cable which, after a complete house renovation I had already put into place in each room. I only had to locate it in my nice new plastered ceiling....It has a battery backup which, of course is needed in the event of loss of power which, of course might be the source of your fire.It is loud enough to wake up all but the deaf. If you sleep through this then there isn't any hope...Now, unlike the older 'smoke' detectors this isn't a radiation type. I do have a fair bit of knowledge of these things being a Chief Engineer (marine) and have dealt with thousands over the years involved in ships and this makes a difference. The radiation type (which has fallen out of favour) worked better. That's because it was more of a combustible gas detector and thus could alarm before smoke occurred. This optical type is based upon smoke stopping a light beam from being detected and thus isn't as quick to operate as the older type. It also means you have to make sure it's clean because a dirty sensor will act to obscure the light beam. So a bit of yearly maintenance needed and if you are a smoker then a lot more.Overall, it is a well made, life saving household essential. However, being mains powered you need to factor that potential increase in cost when fitting. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/81182315-brk-760mrl-thermally-enhanced-optical-smoke-alarm-mains-powered-rechargeable](https://www.desertcart.vn/products/81182315-brk-760mrl-thermally-enhanced-optical-smoke-alarm-mains-powered-rechargeable) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-26*
