DFM400 Reverse Parking Sensors Flush Mount OEM Style 4 Ultrasonic Radar Sensor Kit Audio Alert System - Iron Grey

Very good product. Easy to connect up the electrics. I took the bumper off to ensure perfect hole cuts (use masking tape and dril a pin hole -2mm drill- to start the process). Check back of the bumper to ensure required clearance (Audi TT had reccess in bumper backing where factory fitted units would be installed - very handy to confirm the chosen location!). Also used superglue to ensure that the 3M pads stuck & also used glue sealant on the inner side of the bumper to add strength and secure the flat plate (do not glue the sensor to ensure replacemnet for the future). Make sure you adjust for the depth before sticking it on and maintain up direction of the sensor.Unit worked with factory sensitivity settings & accurate distance gap for each sensor at solid beep. No issues to report and fitted 1 month ago. Do not rush the job, allowing whole day to get a perfect finish!.Good value for money (£50). Recommended

I was a bit dubious about the product at first, all the manufacturers make big promises, but these really are very good.My client wanted a factory fit look, so these were a no brainer really.I really like the punch supplied, far better than using a hole saw.The fact that the sensors are not hard wired all the way to the control box is a bit plus as well! If a sensor was to fail, you can just replace that sensor without having to pull all of the cabling back through the hole that should have been sealed!Overall 10/10Great product and will use the dolphin brand for future clients.

I bought these because I wanted flush-fit sensors, they were a good colour match and the hole punch sounded better than the hole saw provided by a similar kits. However I would not buy again ....Pros+ they work and are good value+ look much better than wart style sensors+ hole punch is cleaner than hole sawCons- THEY ARE NOT FLUSH - stupidly the rubber around the sensor is short by 2mm. So you have two mounting options - sensor flush with deep sunken ring for dirt etc to get in, or the rubber can be flush and the sensor pokes out slightly (see photos). I went with the latter, really annoying oversight and not the factory look expected.- Instructions pretty poor - barely any installation images and sensors lettered with no reason why- Hole punch did warp my plastic slightly around the hole. Hole fractionally too small, had to widen rear to squeeze rubber in. It's already blunting- One sensor fell off after ~100 metres. Bumper off again and duct tape to secure- Including some scotch locks and cable ties would have been nice

Perfect fit

Quite easy to fit, look great when sprayed to match the car, work well, hopefully this continues trouble free

It was easy to install, just need to follow the steps. Hole punch makes a lot better holes than a drill. Looks stunning and works great.

Contacted the company to help with installation on a 2015 Toyota rav4. Offered no help whatsoever and suggested I looked online, even though they claim to fit any car. Very unhelpful.

Fingers crossed, 2nd time lucky.My first kit had a faulty sensor and it took me ages to work out why the sensors weren't working.Purchased a 2nd kit and returned the 1st to AmazonMy bumper came off for a second time to fit replacement parts and now all 4 sensors are working.I do hope that I've not punched holes in my bumper for nothing.
