The design is great - the wiring is to a connector on the back, then the sealed unit just slides into place - makes wiring, fixing, testing and debugging so much easier. Being a sealed unit is good to keep out the dust and any bugs. The LED is blue, just bright enough not to be obtrusive at night. The case is slightly off-white, I would have preferred it whiter, but it is no bug deal. They seem quite sensitive, with ability to "look" down also, and so far have been very reliable.

I bought one to replace a magnetic contact in the garage. Liked the style and the blue light so I have changed my 3 old challenger red light pir s with these 3. I have no pets so the adjustment to activate the lower sensor is very simple. The installation is very simple too and it comes with 2 screws plugs and a small cable tie. I am very happy with them. Plus they are Bosch. It has a spirit level inside so easy to level.

Excellent pir, would highly recommend this product. Will easily cover 20m and very easy to fit, and if ever need to replace ( not likely ) the front comes apart from base and new pir front clicks back in to place without the need to rewire! The bottom sensor can be turned off for pets also. Only pir I would buy!
