Smart Wireless Parking Sensor, Black, Medium, FS122

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.

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.

Returning it today. Great concept but does not work on my Toyota RAV4. FenSens license plate holder obstructs my back up camera. Tried re-mounting it in "truck" mode (upside down). It was a little better but still not satisfactory. Additionally, the FenSens app (installed on my iPhone can only be viewed in portrait view. the display does not rotate when I rotate my phone. Seems like the app was developed for Android and may not be fully functional on iOS. I emailed FenSens customer service a week ago about these two issues, hoping they could suggest some solutions. No response --- very disappointed with customer service. Do not recommend this product.

Did as advertised for a while. While encountering slush on the interstate, one of the sensors broke and the frame also broke. I would recommend it for anyone that doesn't encounter winter weather. The company responds in a prompt manner to e-mails.

The media could not be loaded. The FenSens is a smart wireless parking sensor that connect via Bluetooth using the FenSens app on IOS and Android devices.The FenSens can be used with the front or back of the car, which is a nice feature. Or you can connect two FenSens and have visibility for the front and back of the car.In the FenSens app, you have to create an account and go through the setup before you can start using the device. The app will ask if you have the FenSens positioned in the front or back of the car and the clearance, which is how far the FenSens is from the edge of your car (i.e. if you have the FenSens on the back of the car then the bumper may protrude from the FenSens you should measure from the edge of the FenSens to the edge of the car so the parking sensor can adjust accordingly.The FenSens comes with a quick toggle button that can be attached to the car steering wheel. Within the app, the quick toggle button switches between the parking screen and the home screen (see video and photos for more details).On your phone’s home screen (for IOS), the button will activate the FenSens but will not open the app so if you are a visual person then you want to navigate to the app to see the sensor in action. Activation on the home screen will allow the FenSens to help you park if you have the sound and/or the vibration on. It is important to ensure that you have the sound and/or the vibration on before you use the FenSens because on the home screen, the toggle button can activate the app but no indicators will alert you if the sound or vibration is not on. For my iPhone, I have to turn on the ringer (using the mute switch) to enable the sound to play.The quick toggle button is a great addition for the FenSens although there were a few times when the button did not register for me (see video for example). In the app, the sensor will constantly beep if you are in the parking screen. Beeping occurs every one second when the indicators are green in the app, and will elicit a long beep when indicators show red in the app meaning that you are too close to an object.With a left and right sensor, the app is able to display if you are too close on the left but clear on the right side of the car and vice versa. This is great for angled parking or parallel parking because one side of the car may be too close to an object while the other side is clear so you can adjust as necessary.The parking sensor is a good alternative for those in the market for backup cams or the like. While the sensor does not display live visuals of the outside of the car, the sensor indicators provide the same type of feedback that a backup cam would give you. This is a great option for those who have a hard time seeing the front of their car also. Also, when it is raining, the backup cam may be compromised while the sensors on the FenSens would still be able to work.The user’s guide states that the batteries should last about five months. The app displays the parking sensor battery life on the parking screen and the quick toggle button battery life in the settings menu under the manage devices screen. The guide also indicates that FenSens is not recommended for cars higher than four feet off the ground.From my experience, I found the FenSens to be a good supplement to my car’s existing backup cam. Having coverage for the front and back of the car allows for greater security when parking. It is hard to see the front of my car so the parking sensor is able to help me with parking behind another car when parallel parking.
