Review: EDIT - Sensors are faulty, did not last a year. - 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.
Review: Licence Plate Frame Parking Sensor - I love this new sensor to help alert drivers when they are too close to something. Works great for a back wall, pole, the back of the garage, a carport, etc. I have two teens, one that just started driving and one that will be soon. This is great to help them 'see' behind them just a little better. I put it at the back of the car, with a little help from my son to install it, but they can be put on the front of a car too. It is as easy to install as a regular license plate frame, but this one has special sensors on it. It connects with a smart phone, via bluetooth, to send out an alert if the car is too close to a wall. It detects up to 10 feet away so that is awesome for new drivers (also senior drivers or ones easily distracted). I love that the battery lasts five months before it needs to be replaced too. From the outside it look like a regular license plate frame. It is black and nondescript. But the sensors alert drivers that there is something nearby. This isn't to replace someone using their own vision and judgement driving and is only an additional aid. But I love the added aid in helping my kids learn to park in my garage without hitting the back wall.

## Questions & Answers

**Q: How is it at detecting objects at the bumper corners. I assume it works great directly behind license plate, but what about at my corners?**
A: I have this installed on my front plate I have a back up camera but no parking sensors. It seems to have a wide angle view as it were, also the sensors themselves are adjustable up and down not sure about side to side. I would say that the FenSens could indeed detect objects at the corner(s) of your car.

**Q: My 2006 honda crv has the license plate to the side ( not in the center of the back of the car)  will this still work as intended?**
A: Yes and no. It will work for you if you're using to detect a vehicle in front of your or a wall, but you will have a blind spot on the far side where the device is not placed, as such you could miss a pole or another object that's on that side of the vehicle. It depends on how you would like to use it, but it's definitely better when placed in the center.

**Q: I want this in my dumptrailer, the license plat is low on drivers side, will it work as good ?**
A: If your phone can pick up the sensor via Bluetooth, then it will work. If the sensor is mounted low and to the driver's side, know that you may not detect objects near the passenger side. Suggest you mount it centered.

**Q: Hi, how can i get this product in germany (eu plate version)?**
A: We have it available now on Amazon.de

### ⭐⭐⭐ It works but needs improvement
*by F***N on February 8, 2018*

Ok I will be fair and edit the very bad feedback I left for this product. After ordering for a third time, I finally got a working item. The reason why previous ones weren't working was not because they had software defect as I initially thought. It was because I was sent used items as new and they were already locked to someone else's phone. The third one I ordered, unlike the first two, came in sealed packaging and worked fine. The product still does not deserve a 5 stars because the tap button has very slow response on the iPhone app and sometimes doesn't work. My previous feedback: This is my first time writing a bad review after countless purchases on Amazon. When I saw the product description, I had really liked FenSens. 2 weeks ago, I ordered one. The product came as described. However when I tried to connect it to the app, I kept getting "This is a registered device." error. It was super weird to get this for a brand new device but I said 'can happen, no big deal.' I returned the item and ordered another one, when the second one arrived, it produced the same error as well. So, I couldn't even start using FenSens at all. They don't even have a customer service number that one can call on their website to ask about the issue.
