CISBO SB397 Parking Reverse Sensors Audio Buzzer Alarm Canbus Kit, Silver, Set of 4

These Silver Cisbo sensors matched perfectly in colour to my 2012 Ford Focus in Moondust Silver - if that helps anyone else.They seem to work ok, although not on things that are very low. The solid beeping tone comes on with about a foot to spare, which is about right to access the boot. I find it very handy and am happy with my purchase - especially with the colour match which looks factory fitted.As a side note, on the underside of my bumper the positions for the sensors were already marked out as rounded corner squares (not the circle ones that are also there, confusingly - not sure what those were for, possibly the more advanced parking assist sensors) - i found pushing a sharp screw into the centre of the square from behind the bumper made a small mark show on the front that you can use as a guide to drill into, it's a lot quicker than measuring and marking up each sensor position.

After fitting CISBO branded some years ago to a 1999 Mercedes ML320, I took the plunge & had them fitted to my A4 B6 whilst it was in the bodyshop getting a nasty scrape repaired to the rear bumper. Usefully, Audi marked the bumper rear with the cut-out circles to aid fitting. The sensors work perfectly; as they did for the 4 years I owned the ML. The sensors have a square edge as opposed to the smooth tailing off edge shown in the images, but they still look good. Should I end up in the future with a car that needs sensors, I again would purchase CISBO over cheaper options. I looked at more expensive options for the Audi, but thought why? CISBO do a great job & have proved to be very reliable.

The sensors were very easy to install and set up, baring in mind that I looked at another car of same model to see what cables to tap into, however the sensitivity of them isn't great. It seems to start beeping only 800mm from the object, and isn't consistent each time you useIf you are slightly anal with the workings of this sort of thing, then go for something a bit higher in quality and value,The silver colour match is perfect for Astra 2008,The volume is the buzzer isn't the loudest so needs to be located somewhere bearing this in mind.The box does have a sensitivity adjuster but it doesn't seem to do much.Ps they now seem to be so untrustworthy that they are useless, truthfully and honestly, avoid this , they are really poor do not pick up things and beep randomly even after you've hit something.

The kit is barely acceptable for it's price, but sometimes is malfunctioning (The buzzer beeps continuously regardless the parking space available.

The sensors were just as described and the service was quick and efficient with a good colour matchMy local garage was impressed with the price I had paid and said that they were a doddle to fit.Although not advertised the box contained the correct sized hole cutter.Recommended!

Does what it should would recommend

not sensitive enough does not start beeping till about 70cmm turned it to full sensitivity makes no differance

Rubbish, and a waste of money as they lasted one month and packed up, no response from the seller!!! Buy a better make and spend a little more for quality.
