STKR Concepts 00-246 Adjustable Garage Parking Sensor Aid, Dark Gray

This sensor attaches it self to the garage door's rail with the provided mount. The mount does not require any tools as you just need to push it in place and the sensor stays in place. To remove, just use a flat screw driver to push up the tabs. The sensor is easy to remove from the mount for battery replacements. It uses 4 AA batteries and there is NO USB option for it. Setup is easy and I just parked my car closer than what I need, clicked the button once to set the distance, then park away. The response is not super fast or super slow, so it responds fast enough when parking a car at slow speed. So far, I have been able to park my car extremely close to items with no issues. It has green, yellow, flashing yellow and red alerts. The red alert emits a tone. I park my car on using the flashing yellow. How good is it? I purchased another one.

This is definitely a first-world problem, but parking the car in the garage varies dramatically between a bike rack and bikes fitted to the car vs. not. When the bikes are on the car's rear tow hitch, the car needs to be around 3 feet further forward in the garage to clear the door. A neighbor showed me this device and I immediately purchased one as they were on sale. It seems well-made and was very simple to install using the supplied Velcro for the main unit and the sensor below. There are two options for powering the unit, either 4 x AA batteries or via a USB cable. The unit is not supplied with a USB cable or power supply but most households now have a kitchen junk drawer that has plenty of these from other products. And if not they are readily available to buy at a low cost. I connect mine via the USB cable as there is an outlet close to where the unit was fitted. Setting up the parking distance is a simple case of pressing the red button on the front. I have it calibrated so I can easily judge the ideal parking distance for when the bikes are on the car, or not. Not sure how long the Velcro will stay stuck as the garage is hot during the summer but so far its staying put. Overall a great purchase.

Easy to set up, works well. Battery life is a joke. Requires usb power supply. Cycling on and off whenever ambient lighting changes drains Battery within a week

I ordered this due to it being exactly the sort of aid we need for our garage, and because the free-standing stop signs tend to lose durability after 1-2 years and bow over. This device does have a USB-C power input on the side, but I have now tried two different STKR units now, and the USB power feature is completely non-functional on both. The exact same USB power works fine on my phone and all other USB-C devices I tested the power with, so it is not an issue with my power supply. I have seen videos of units working on USB power, so I know it's possible, but when 2/2 units are defective for me, I'm not going to continue ordering this same product repeatedly until I get one that somehow works. As both units I received were defective, this product appears to have terrible quality control or build quality. I did not test my units with batteries, because battery life is reportedly terrible and I need something I can run on wall power. These do not reliably run on USB power based on my experience.

Good quality and easy to put up. The colors are bright and let you know when to stop. This is great.

This works great. This is my second one - the first one worked fine for several years but I accidently damaged it (treat the sensor part carefully.) Once you get used to having help getting the car in the right place it was hard to do without it. I think the new one has brighter lights than the first one. Just go slow, there's not a lot of distance between green, yellow and red.Don't plan on using it with battery power though, batteries only last a few days. I already had a battery eliminator so I'm using that instead of the available usb port. The old one didn't have the usb option, so I had to buy a battery eliminator kit so I just used that on the new one.

So far one star. The clips seemed far too small to fit on my garage door tracks. The company should specify the size of the track this product fits in the description instead of assuming all tracks are the same size. After contacting the company, I came to realize that the clips would fit if I pushed very hard. The description should include the dimensions of the track this product is designed to fit, and a diagram or drawing of how to install the clips.Once I installed the clips, I discovered another, fatal, problem. On my garage door the fitting that attaches to the wire from the counterbalance spring wraps around the track and hits the clip for the side sensor as the door comes down. This product will not work with my garage door unless I find a way to mount the sensor to the wall of the garage instead of to the track. It would have saved me a lot of time, and Amazon and STKR a lot of money, if I had been told about this incompatibility before I purchased the sensors. As it is, the two sensors I purchased will probably have to be returned.I'm raising my rating from one start to three, because the sensors do work. But three stars instead of five due to the problems with the track discussed above, plus two additional issues.I managed to mount the clip that holds the sensor on a wood block using two #6 screws, and then I mounted that wood block on a stud next to the garage door. I am not using the door tracks at all. So, now on to the issues.The USB power cord provided with the sensor is 1 FOOT LONG! That is a joke. Even people who may have power outlets in their garages would not likely have one within one foot of the sensor. Why supply a UBS power cord at all if it is going to be ONE FOOT long? I have an outlet near the sensor, but I needed a 6-foot USB cord to connect from the adapter in the outlet to the sensor.The second additional issue is that the USB C power jack on the sensor is at the bottom of the ultrasonic sensor itself, not on the body of the device. The sensor is attached to the body with a rather fragile plastic arm. If the power cord is somehow snagged or pulled that could cause the arm with the sensor to break off of the main body. I can't figure out why any engineer would put a power socket on fragile arm instead of on the far more robust body of a device.
