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.

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.

The concept is really nice. But I have been having problems getting in touch with the company as the left sensor doesn’t work at all. It has worked only once or twice since I Have bought it. Great concept. Execution and customer support are really questionable. If I don’t get a response soon I’ll return the product. 2 stars for the concept.

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?

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.

Does not work correctly useless
