Let customers speak for us
from 2540 reviewsGreat bumper magnet! Not sure what to haul with this trailer anymore though…

The constant desire to order more of these is likely to ruin my credit. High quality, obviously insane and hilarious, and the best company for customer service. Buy all the stickers!!!

The quality of these bumper magnets is great, they stick nice and snugly to my car and don't budge. The print quality is great. Would buy more unhinged designs again!

This is an intimidating sticker to put on your car, hence why I opted for the magnet. Still, I was mulling over whether or not to put it on. My mom told me not to, thinking it would make me a prime target for road rage. My friends thought it was hilarious and encouraged me to do so. “Real.” They would say.
The answer to my ambivalence came when my sister called me crying. She had side swiped her precious car, Otis, on concrete beam when trying to exit a tight parking garage. She was embarrassed and upset. I tried to console her, but still she cried. And when I saw it in person, I understood why. The damage was egregious, probably requiring the whole door panel to be replaced. “People are gonna see my car and think I’m a bad driver!” She said, “They’ll know it’s a girl car and way women are bad drivers!”
Ah, the accursed stereotype threat. Will we ever be free?
But I had an idea. I grabbed this magnet and stuck it over the damage.
“MOVE I’M OVULATING.”
My sister cracked a smile and took a picture. “That actually does make it better.” She said with a hint of disbelief.
“It’s perfect.” I stated.
5/5 stars

The stickers are great. They are handling the PNW weather just fine. The really astounding thing, though, was the customer service.

Do I technically work for law enforcement? Yes. But in this household we only Back the Dew 🫡

Hilarious. I got 3 stickers and one magnet, and they all seem to be high quality. Can't wait to put them on my car!

I love it exactly what I wanted

So much better than anything I've found anywhere else, truly custom and looks great. Don't wait!

Now everyone can know that I do in fact have that dog in me. Package came quick and turned out great!! Comes with instructions on how to apply it and a cool promo code for another purchase. Super happy with it, will be purchasing more and again!

I spend a lot of time saving silly bumper stickers/magnets bc it's the main aspect of my personality bless youuuuu making this lol

Arrived super quickly! Exactly as described, high quality!

I needed this for my EV

So funny, I love it! Arrived fast! 🍅

The text is clear and it's a good size, definitely will be buying from them again 💜
