STKR Concepts 00-382 Adjustable Garage Parking Sensor Aid, White

Light stays off unit when idle. When it senses the car approaching it turns green, then yellow, and finally red at the stopping distance that I set up. Very easy to install. Setting the desired stopping distance takes a simple push the button and that's it. I have it connected to usb c power and have had no issues; you'll need to supply your own usb cord and power adapter, but can also be powered with AA batteries if that's a preference.

Update: Updating to 5 stars. The second STKR Parking Aid has worked perfectly since received. Very accurate positioning of our car relative to garage wall. We've been using batteries since received and they are still going strong after being installed in March. Highly recommended !The first purchase was defective. After installing and positioning the car properly, the red light continued to flash on periodically, running the batteries down. I returned the item for an exact replacement. The replacement works fine without the problem. It does provide an accurate position relative to back of the garage wall. Easy to use once properly installed. Don't know how long the batteries will last, but will find out.

Revised rating. Upon installing the garage sensor it failed to detect our auto, so I gave a one star review. In the process of returning it to Amazon, I contacted STKR customer service. Turns out an adjacent metal cabinet was interfering with the beam. I relocated the sensor button and resolved the problem. Unit works as advertised. However, if you walk in front of the beam and your parked car, the unit lights up for short period, thus depleting the batteries faster, reason for four star rating. STKR Customer Service was very helpful and worth calling if you encounter problems.

***UPDATE***It failed a week after my initial review. First I noticed that the batteries were already dead not knowing that it was not really shutting off. One night I had to go into the garage and it was freaking out and the lights were flashing like a dance party - I think temperature changes and humidity are not great for the sensor and I checked the second set of batteries they were still good. It also would not work randomly so you never knew if it would work when you pulled into the garage. .....Back to the wood parking blocks until I find a better solution. as other have stated I would not recommend this product.---------------------------------------------------------------------------------------------------------Easy to set up (battery or USB) and it has worked well for the first few weeks. It is a perfect easy solution to parking in the garage without the need of parking blocks. Kids were always tripping on them and made it hard to clean the garage floor. I will update the review if it fails prematurely. fingers crossed!

I mounted this on my metal cabinet directly in front of my car. I tried settling the distance at 39 inches several times by pushing the distance set button for different lengths of time. This has not worked once. The green and yellow lights never come on and the red only comes on when about 6 inches from the sensor. In my opinion this is junk. I will be returning it.UPDATE: I found there was an object on the floor of my garage that was interfering with the IR beam that measures the vehicle distance. After relocating the object this sensor works flawlessly.

Seems to work okay. After adjusting the sensor numerous times, I realized that I needed to pull forward for the sensor to work accurately. (This is my opinion and has not been validated by manufacturer. ) once I figured this out l, the sensor (so far) works as advertised.For reference:I normally back into my garage. I measured the height of my bumper and aligned the sensor at the middle of the car. I tried several times backing into the garage and sensor would not activate.I also wish that the light would show some sort of acknowledgement after the prescribed parking distance is manually adjusted.Perhaps have the light show “red” after adjusting the prescribed parking distance, then “green”. At least this would indicate that the new distance had been adjusted.
