FenSens Smart Wireless Parking Sensor - 100% Wireless, Easy-Install, Available for iOS and Android

Horrible product. Apps doesnt connect when needed. How long somebody can wait to make the apps connect with the device? Many vehicles positioned the rear licence plate in middle of the trunk lid. But incase of this, sensor only works if you install the plate in your bumper! Othereise for height, it doesnt work. How they expect to change the plate position of the vehicle?

I had written a glowing review on Fensens, and need to go from 5 stars to 1.I use it on the front my my Lexus, and the right sensor has stopped consistently working. You get zero from the left, while the right continues to work. Contacting Tech support, is brutal. I'm getting short replies, "pull the battery", which I did - with no success. WORSE - there is a thin rubber gasket that fits behind the batter door. It's 100% impossible to keep it in place putting the batter door back on. EVEN WORSE - the batteries pop out the multiple times before you can finally get them to stay in, "try" to use the gasket and get the door back on. The only way around the design flaws is to remove the Fensens completely. I asked Tech support if there was a trick to keeping the gasket in in, "wet it and it will stick". No it doesn't.With the left sensor working only 1 in 20 uses, terrible battery change issues, I feel like I got screwed right at 12 months. It's a shame. The concept is good, it fills a problem/need if you don't have front end sensors. Sadly, design flaws for the battery change, and failing sensors makes this useless.It gets WORSE - they updated their app to work for both a Camera and a Sensor. The app is confused when you start it up. Even when you select Sensor, it tries to start up a camera that doesn't exist on my car, creating an error message. What a mess. So 5 starts to 1 - Hope this gets the attention of the Entrepreneur. He has messed up a great idea.

Easy to Install. Only one major issue Blue Tooth constantly conflicts with my vehicles Uconnect system. Visual Display and Vibration work on phone, however beeping alerts cut out.

I have an older Fiat 500 Pop that lacks any kind of backup alert capability. I had looked at the Pearl backup camera but the price was just to high to for comfort. I was on Facebook one day recently and an ad for the FenSens Parking Sensor appeared. I read th description, I watched a couple of Youtube videos and I decided to go for it. Installed it two days ago and am still getting used to the slightly confusing interface but it does work as advertised.PROS:Easy to install and pair with my IPHONE SE.Seems robust enough and looks attractiveIt works as advertisedCONS:Slightly concerned about the water resistance capability of the battery compartment. Does not seem to have any sort of O-ring type seal.(but I did just take the car through a car wash and it worked fine after)Instructions are a little confusing.Sometimes I have to close the app and reopen for the sensors to start sensing. Wish you could just have it constantly available as long as the app is open.Bottom Line - The price is maybe a bit higher than I would like but it works and I am satisfied.UPDATE - So I have been using the FenSens for several months now and I finally had that moment when a fender bender was avoided at the mall parking lot. I have it installed on my Fiat 500, a very small car, and found myself parked between two large SUVs. As I backed out, unable to see anything for the longest time, my Sensor started beeping and I noticed a car fly by. If I had not hit my brake when the sensor started active pinging, I am sure I would have been missing a rear bumper. SO THANK YOU FenSens, you saved my Fiat's A$$.

Does not work correctly useless
