These are a value for the price. Driver's ed instructor was selling similar magnets, $10 EACH. These magnets work well and I can definitely tell that other driver's are leaving more space and showing more patience to my learning driver. I wish they came in packs of 4 so that I could use one on every side of the vehicle. One tip: the magnet is thin and will start curling up a bit - be sure to gently bend the magnets in the opposite direction of the curl before placing them on the vehicle. This greatly increases how well they stick on the vehicle. We lost one magnet early on because the magnet was partially curled away from the metal, allowing wind (from driving) to get behind it and pop it off. Have not lost any more since we started bending them a bit before each use and we've been at highway speeds.

They are exactly what they say. Stick well, very visible, reasonably durable.

Great product.

Excellent and helpful. They are as described. When they get warm--say if they're left inside a hot car--they do bend out of shape. But for the most part I got them to flatten again.

Love these! My teenage twins are driving !!!!! With prayer and these reflectors I feel safer. LBS

Very helpful to me since I was learning how to drive most importantly here in NYC

Sticks on the Prius C just fine, hasn't fallen off in rain and serious dust. Very large. Best deal for $.

Great idea, helps my daughter feel confident that others will understand her hesitant driving, and does reduce aggressive tailgaters. I really like the 3 pack as another review mentioned; put one on each door and the other on the back of the vehicle. The only reason I didn't give them 5 stars (4) was because they could be a bit larger. The dimensions are listed correctly but in my opinion they would be more effective if they were slightly larger. These are the size of a standard rectangular bumper sticker if not even smaller, so unless a car is right by you it is difficult to read. I do think these signs make some rude drivers pause when they see them as several people have asked if I am an official driver's ed instructor, and she is my paying student (she is my daughter, completing the mandatory parent supervised behind the wheel practices of 30 hours min.) One tip; be sure to lay them flat and stacked all together when storing in the car as they are rather thin plastic/magnetic material (think free advertising magnets for your fridge) and the corners will curl up and stay that way if crammed into the door pockets carelessly. Other than that, these have been well worth the price for a less stressful driving experience for both my daughter and me!

Good quality.

We love these magnets. They are easily seen, especially at night.
