Great replacement for old smoke alarm Our existing 20 year old smoke alarms were continually being set off by the slightest whiff of smoke from cooking, and even steam from the shower. We thought that we'd have to phone an electrician to get new alarms fitted but were surprised to find the exact same model on Safelinks. Fitting was as simple as disconnecting the wires, sliding the old ones off and sliding new ones on. The little tool supplied for releasing the catches worked well - though it's basically just a small screwdriver. Very pleased.

Great products, great service, great website, why go anywhere else? As somebody who has a technical brain (I am a chartered engineer) but no knowledge of this product except that it is a necessary safety accessory for any home. I was presented with two alarms in our home that displayed warnings that the batteries were at the end of their useful life. The units in our home were 10 years old (we purchased the house 7 years ago), so imagine my surprise when a Google search found your site and sitting there were replacement units waiting to be purchased. Question %u2013 Would these replacements fit 10-year old housings and save me a new installation? The site content was brilliant I didn%u2019t need to speak to anybody, the descriptive text was crystal clear, I placed the order, they arrived exactly as forecast and they took just minutes to fit. Great products, great service and because of that I also purchased your CO2 alarm and that again took just minutes to fit

The safety catch is not as easy to release as it sounds! The connector plug is easy to remove but difficult to push in. In both cases it probably would be easy if one had the base and the alarm on a bench, but it is a different matter up on the ceiling. However the replacement was achieved successfully and the idea of being able to do this is brilliant.

We firstly made a call to make sure that our old ei150 could be replaced with a newer Easichange Replacement Smoke Alarm for Ei151, Ei151TL, Ei151TLH, which it could. We then placed the order online. The 2 alarms we bought we packaged well and arrived in a reasonable amount of time. To install them was a breeze, took about 30 seconds for each one, clip in the electrical connector and slide into our existing ei150 holders. Very happy indeed, thanks.

Excellent service! Person I spoke to (Zak) was very helpful and knowledgeable without being patronising to one who doesn't know the first thing about smoke alarms. A lot of other companies could learn from the efficient way you obviously run your own. What a change to say "well done". I'm sure the smoke alarm will give many years of useful (and necessary) service.
