Road Reflectors Pack of 10 | 4 by 4 inch Street Pavement & Asphalt Stud Markers | Great Reflecting for Speed Bumps, Sidewalks, Pedestrian Crossings, Freeways & Driveways | Industrial Grade (Red)

I live in a row home in Philadelphia PA. It's very tight in the ally behind my house and I used these to glue to the ground with water resistant outdoor glue. I've done this to help prevent a car side swiping my car while maneuvering through the ally. The photo was taken from inside my car in the ally. They're not cheap, yet you do get what you pay for. Very strong with some weight, very bright and reflective, underside is a sandy material giving the glue something to stick too. I've noticed cars instinctively avoiding them making my parking spot safer.

High grade, well built product that provides a nice edge marker for my narrow garage doors.

The reflectors seem really quality made but one of them broke after it was run over not sure what you can do about thatThe ones that the state uses don't seem to break and my thought is these look the same

Purchased for newly fabricated concrete curb in the hopes delivery trucks will discontinue running off driveway and breaking sprinkler heads.Product is heavy and well made. We erroneously omitted butyl pads and found glue would not stick to concrete. So, spend another $17 and butyl pads work great with this product. Very happy with purchase.

These reflect light, but only from a specific angle and with a strong light source. If you’re viewing them from the driver’s seat with your headlights hitting them, they reflect (see photo). But if you view them through the lower lens of a backup camera with the dimmer glow of tail lights, they’re barely visible at all (see other photo). It’s too bad, since I was mainly buying them to aid backing out of the driveway at night.

My box of then of these reflectors arrived very promptly. They are heavy enough and with a rough enough bottom that they can just sit in place on your driveway without your gluing them down. At night they reflect clearly once your back-up lights get close enough. They're big enough to be visible in daylight too. Overall I'm impressed. They've been a big help in backing our cars into the right spot.

The reflectors appear to be consistent in size and of good quality and weight. There are some “tricky” areas and curves in the road to our house and we wanted to make certain those areas are outlined with a bright color for our safety and the safety of our guests.

We glued these down on our driveway but they are not reflective at all. Support is terrible- you can’t even ask a question. They seemed very sturdy and heavy, but we should have checked reflectiveness at nighttime instead of gluing down during daylight.
