Car seat

Does anyone have an opinion on the Urbini car seats? 
After a ton of research I decided to buy a britax car seat. My mom, decided to "surprise me" less than four weeks before my due date. And get me a second hand Urbini travel system. It looks like it's in pretty good condition, only a few stains that look like they would probably come out once it's washed. I love the car seat I ordered and I'm not sure what to do with the other. I like the way the car seat fits to the stroller, but that's about it. I know most people would love that kind of surprise, but not after I just bought the one I actually wanted. I don't want to seem rude or ungrateful but I don't know what to do 😩
