STKR Garage Parking Sensor – Adjustable Ultrasonic Car Stop Assistant with Red/Yellow/Green LED Display – Set Stop Distance 6"–6 ft – Battery or USB Powered – Easy Wall-Mount Install – White

We bought this parking sensor aid for my 80 year old mother (who still is healthy and a good driver) to pull her car into the garage. The directions were clear to follow and we set it up in just one minute. The only problem you would have is if there isn't an outlet nearby to plug it in.It's not very big and doesn't take up much room but It lights up brightly and is very visible. The yellow light lets you know that you are near and when it turns red it is time to stop. We've had this item for a few months now and it works great. We were recommended this item from a family member who has had it for 2 years so it seems like it works for a long time and worth the money.

Finally! A basic, simple and accurate garage car stop! I recommend using the usb cord plug in, so you don't have to mess with batteries. This is a great gadget and will let you park your car in the same spot every time! You can push the button to "learn" a distance, or use the default setting. I stuck this on my new garage fridge so it won't get dinged up like the old one did.

Workswell but doesn't need to be this obnoxiously big with the manufacturer's name so prominently displayed.

This thing is about as helpful as a squirrel with a flashlight. You’d think an “adjustable car parking sensor” would, I don’t know… sense something? Instead, it just blinked at me like it was confused to be alive.Tried adjusting it. Re-angled it. Yelled at it. Nothing. Sometimes it went off when nothing was there. Other times it stayed silent like a teenager getting caught sneaking in at 2 a.m. Bottom line: if you’re counting on this to save your bumper, start budgeting for body work now.It’s basically a glorified light on a stick. I’ve had more accurate guidance from a Magic 8 Ball.

I was hesitant buying this after reading some reviews. But at the price, it was definitely worth the try. And, the price really is what makes this a good choice. I'm not sure how varied the products is going out, but my unit has worked great for going on 2 months now. I have been running on the supplied batteries the whole time. I'm going in and out at least twice a day. For the price, this beats almost all the options out there.PROS:What I like most about this over almost any other solution is that it doesn't rely on you hitting your parking spot at a consistent place -- like a laser on the dash, or some other spot. I can come in at almost any position and it's just going to register off the grill of my car. It doesn't require a tennis ball hanging from your garage ceiling, and doesn't leave parking blocks on the floor that get in the way.The position registration is consistent and repeatable. When I set it up, I wanted about 6 inches of gap between the bench at the back of my garage. I parked, pressed the button to set the distance, and it is spot on every time. It detects the vehicle about 4-5 ft away, and the goes to red almost exactly 6 inches away.I actually like that it's battery powered. I can undertsand if the battery was draining after a few weeks, or maybe a month. But for me, it's been going strong for almost two months now. If I have to change it every two months, that's not a problem. I'm also going to try with some rechargeables when it does finally go out. I would consider a plug in USB, but it's in a place I don't want wires coming in from. I'd also consider a USB bank, which I might also try.CONS:If you're working in the spot you park, it's going to go on and off. That might drain the battery, but I 3D printed a cover that goes over the sensor, and that stops it from happening. This is far better than having a tennis ball hitting your head, or floor stops you might trip over over and have to reposition.About the only other problem I've had is that the adhesive came off once, but that's because I have it on a narrow vertical rail on a shelf. But this is easily fixed with a screw plate, or zip ties.Overall, it's been about the best solution for me in my garage. Convenient. Easy Install.

Works well and nice to have the USBc power and/or battery power options. Easy to set the stop distance within the specified distance range (I didn't try it outside of that range because I needed about a 3 foot distance for my application). Would be nice if the little sensor had a way to be mounted by screw as an option (its mounted by double-sided tape) in order to make repositioning it easier (my first mounting location, centered side-to-side to the front bumper, was just a few inches to the side of a cabinet and this caused some interference with the range-finding - so I moved it a foot or so to the side and that location has worked out very reliably, I just needed to then supply a new piece of my own double-sided tape). Anyway, has been working great now for a week -- my wife no longer pulls in too far and making it hard to cross in front of the car and pulls in far enough that the garage door doesn't scrape up the back of the car (which is really what prompted me getting this device and some touch-up paint to fix the scratches the garage door did to the back of the car last week :-/ ).

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.

This is a cool gadget. It’s simple and it works. As I pull into the garage it’s green and as I get closer to the wall that I have occasionally run into it turns yellow and then stop. Red light.
