STKR Concepts00-246 Adjustable Garage Parking Sensor Aid, Dark Gray

7/2/2025-Received item, set-up and attachment to the wall 10 minutes max. I used a screw for the indicator lamp and the 3M Velcro for the sensor below. Takes USB-A or 4xAA batteries (I used batts). Does not come with the USB-A cable. Park your car where you want it and hit the red "set" button up front and your done. 6 inches to 6 feet is the range it works. (The white unit that they sell is less-my car was about 5 feet away). The unit turns red when you need to stop. Try pulling the vehicle in several times and it turns from green to yellow to red (means stop). So far so good, I really like the unit. Next test is the longevity of the batteries and the unit and the consistency of the unit. More to come.

I decided on getting this type of parking aid as I didn't like the ones mounted on the garage floor. I do a lot of work in my garage and those would end up being a trip hazard. I used others where you point a laser to a spot on your dashboard but after awhile, the laser gets dim or sometimes it gets knocked out of alignment. Not a problem anymore. I've had this for 3 months and it has always been accurate.

I used the original version purchased back in 2012. Only in the past 6 months or so it began to act up. Just purchased the newer "2020" version, along with a separate USB power pack. Please note the following:- The PDF instructions linked on the amazon page are for the original unit (battery operated only) not the "2020" version.- The Amazon page details state repeatedly the external power source uses a "standard USB" connector. There are 3 standard USB types used today. Mini USB, Micro USB and USB-C. USB-C is the most current. This unit that I received uses the most current USB-C. Which it actually states that in the instructions provided with the unit. Would be nice if it was stated more clearly in the page details or the linked PDF to avoid buying the wrong one.- I was reading one of the other reviews asking about the "charging" port on the unit. The port is NOT a charging port and will NOT charge any rechargeable batteries you may put in it. It is an optional power port only, so you can run on line power or batteries (or both with battery as backup in case of power outage).

Review:This review is not about the product itself. I’ve been using the same device for over a year and it performs exactly as advertised. I use rechargeable batteries and replace them weekly with no issues. The product is reliable and does the job well.However, my complaint is with the seller. I received the package in a sealed envelope with a label indicating it was new and ready for sale. But upon opening it, I discovered that the manufacturer’s packaging had already been opened. The device showed visible signs of prior use, including scratches and remnants of adhesive tape on the back.I paid full price expecting a brand new item, not something that looked like it belonged in a recycling bin. The fact that it was resealed and shipped as new is a serious breach of trust. There was also a note on the store page saying “only one left,” which leads me to believe this very item—used and repackaged—was passed off as new.This kind of deceptive practice shows an alarming disregard for the customer. I strongly recommend avoiding this seller due to the lack of transparency and respect for buyers.

This lighted sensor works great. My new car only has about 6" clearance on either side of my older garage door. The first one worked so well I bought another. Now with 2 sensors blinking green, yellow, or red on both sides, it makes entry and exit so much easier. Into week three of daily use with no problems.

I’ve had one of these for about eight years and buying another. My garage gets pretty hot in the summer. These things are better than using tennis balls or other devices. This is a great product.

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.
