Product clearly described - Order / Delivery excellent The alarm fitted in my flat needed replacement after at least twelve years of service. A brief online search brought me to Safelincs, where I was able to locate the replacement unit needed. My order was dealt with immediately and within three days the replacement part was fitted and working. I am not a very practicle individual, but at almost 79 years of age, I was able to fit the replacement unit without too much difficulty. Thank you for a top rate product and excellent service.

Had been searching shops for this product but could not find anywhere that sold just an easy replacement kit that I could fit at home onto the base that is secured to the ceiling. So easy to fit.

The smoke alarm replaced was 15 years old, as was new when the house was built. Was simple to swap over, and hopefully will last as long again. Very effective when kids are cooking burgers or bacon, they really give the game away!!

I bought the 'Easichange' replacement kits to replace my end of life EI151 and EI156 smoke alarms. Your web site promised they would be easy to fit...and that has turned out to be the case. I had no problem changing them (other than tamper catch a bit fiddly). Very satisfied.

I really did not want to purchase a whole new smoke alarm if it was possible to do a simple 'one out, one in'. Yours was the only website I found that offered this simple replacement kit (though I wasn't searching for hours) and it worked brilliantly - a two-minute job! Thanks, it could not have been better.
