Review: Great value and super easy to fit! - These burglar alarm contacts have been excellent so far. They replaced my old sensors seamlessly, fitting perfectly into the existing wiring and mounting holes—no drilling or reconfiguring needed. One reviewer even mentioned they were “perfect fit for replacing an Aritech sensor” . Why it stands out: Excellent value — you get two detectors, so one for now and a spare; as noted by a customer: “for the money it’s great and saved a call‑out charge” . Quick and easy installation — the “very quick to install” process receives consistent praise . Reliable performance — firm magnetic switches and strong wiring quality keep everything functioning reliably . A couple of minor notes: It’s wired, so if your alarm system is wireless, you’ll need compatible setups. These are standard grade rather than premium commercial units—but for home use, they deliver excellent results. Overall: Fantastic product for anyone wanting a fast, affordable replacement for door or window alarm contacts. Great value, straightforward fitting, and solid performance. I’m very happy with the purchase and would definitely recommend it and buy again.

Quite cheap and did the job,bought to replace cracked one

### ⭐⭐⭐⭐ Really disappointed
*by J***E on 7 January 2026*

Fitted these to replace existing in tandem shop door chime detectors which kept “beeping” for no apparent reason. After fitting the new ones chimes did not work at all and investigation showed that one of the new detectors was permanently open circuit, if I had not been desperate I would have returned the new ones for a refund but as one of the old detectors was still working I opted to refit the old one together with the “good” new one Since contacting supplier they have resolved the issue hence revised rating from 3 to 4
