MR CARTOOL Parking Aid System for Garage，Car Park Assist Sensor System / Smart Parking Aid Gadget Safe Light Parking System Assist Distance Stop Aid Guide Sensor for Home Garage

THE DISTANCE WAS TO SHORT FOR MY APPLICATION. YOU HAVE TO PARK WITHIN 2 FEET TO WORK.WE NEEDED 4 FEET STOPPING DISTANCE AND DEVICE IS NOT ADJUSTABLE.I RETURNED ITEM WITHOUT A PROBLEM AT AMAZON.

I hung in the back of the garage and it stays beeping when I open the garage door to come in.

I really like this and it works well. The only downside is the battery dies after 2 days! I haven’t been able to use it at all because I would be literally changing the batteries every other day!!! I do not recommend!!!!

I installed the unit as seen on a Utube video- I first used 9V DC adaptor and removed it and used a 9V battery- Could not get the yellow light to go off and when plugged in there was a continued audiosound or buzzing- I followed the installment instructions to the tee- I worked on this unit for over ahalf of hour and still it would not operate properly- As far as I am concerned, this unit is a piece ofjunk--You have to watch what you purchase online...--

Worthless! Poorly made with instructions written by someone who failed an ESL class.

So far it’s doing everything I hoped it would do.

Well, so much for that. This sensor goes through a fresh 9V battery every 2 days, and there's no cord with it to plug into a wall for power. Not only that, the light is finnicky and doesn't stay lit for long as you're pulling in. I'm just gonna stick with the good ol' tennis ball on a string method... Don't waste your money on this. I'd return mine except my roommate already tossed the packaging several weeks ago.

It work like they said it would do. Very good product.
