STKR Concepts00-246 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.

Works great, easy to install, wish I had known about these sooner.

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.

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.

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.
