These seats are gold! I have one for my 5y old and one for my 9mo old! Safe & minimal. Very ascetically pleasing as well

  • Size
Style: Radian 3RXT SafePlus Color: Black Jet
This product is perfect if you own a smaller car but not a smaller family. I am grandmother to three young girls who are all still in car seats or booster seats and I drop off and pick frequently at day care and kindergarten. I own a Mustang Mach e. I could not get three normal sized car seats in my car, but with this car seat I can get all three in my car. This car seat has the added advantage that I can use this seat from toddlerhood to booster seat with very little fuss and bother. This car seat is worth every penny. ... show more

  • Extremely heavy, overly complicated and straps won't tighten properly on smaller children.
Style: Radian 3RXT SafePlus Color: Gray Slate
Purchased this because of the narrow width to use as a travel car-seat on a commercial airline and with a rental car. I would strongly recommend against buying this if you intend to travel with it. It is extremely heavy and nearly impossible to maneuver on board an airplane. It is supposed to be good for children from birth to age 10, but because the straps have to be made to fit bigger kids, they won't tighten properly on a small toddler. I took the cover off to wash it prior to use, and needed the have the instructional video playing over and over to understand all the steps to disassemble and reassemble the seat. Replaced it with a much simpler and lighter carseat for travel. ... show more

  • It’s huge !
Style: Radian 3RXT SafePlus Color: Gray Slate
This car seat is huge but love this brand. It is pricey so recommend catching it on sale. This is for my one month old but my 2 year old also sits in the same seat. I have 2 car seats and a booster seat and they all fit next to each other in the back seat. We have a Chevy mailbu and a Traverse for reference. It’s so safe and easy to clean. It’s my favorite car seat and won’t turn back ! ... show more
