You can always buy cheap - but if you want something to work buy quality.Owned this for over a year and in that time it has worked reliably.Easy to fitEasy to setGreat visual deterrentLoud.Quality brand, from my experience I have to say buy with confidence.

Great bit of kit, the alarm has a good loud pitch , the various sensors are easy to install & it is a great price.

As there is no wiring involved, the installation is straightforward. Yale designed the alarm system with all the main electronics located in the external siren, rather than in an internal control box. This arrangement does have a disadvantage in that the siren needs to be accessed not only to change its batteries, but also if extra detectors are added post-installation, or if there's a malfunction of any sort. Another downside is that the siren beeps when it's armed or disarmed, telling potential intruders when the property is vulnerable.

Installed after an attempted burglary and looks a good quality system, took a while to get installation correct but it should give me the protection I need,

I've had mine 2 year now absolutely brilliant hasn't missed a beat no false alarms never had any problems with the kit at all. And the batteries are still going strong have not had to change them yet even in the FOB. I've left it a while before reviewing so I could give a 100% honest review I would highly recommend brilliant deterrent

Easy to set up

Great value, simple to install and works well, although previous one started false alarming after a few years (but for the price, not worth repairing). Current Amazon description on the new Yale system is misleading, as it claims 6 x AAA batteries are required (included), whereas the main unit runs off much larger 'D-type' (formerly U2) batteries (included). I nearly ordered incorrect AAA lithium cells to perform better in cold temperatures. Other accessories are run off button batteries (also included). BIG ISSUE is that Amazon offered the (compatible?) Key Fob at point of sale, which I selected as part of same order. After spending over an hour during installation and failing to configure the key fo, then on phone to Yale Tech Support, it seems AMAZON IS SHIPPING WRONG KEY FOBS. They look identical, but for this system, it requires HSA6060 (not EF or SR systems) Key Fob. The Yale Tech Support guy seamed fed up with all the calls received recently. Frustrating & waste of time for me too ! ... hence 3-star review.

Not the easiest to set up. You need to follow the instructions to the letter, without distraction. Siren is very loud and not great to hear when up a ladder.
