Well I for one won't buy it but I have to say if I did it's because it seems like everyone else is. I don't want to sound rude but how many carseats is one supposed to have? I mean I'm sure there are some who are buying it cause either thier children have outgrown or about to out grow thier current seats, but it also seems like a lot are buying it cause it's the newest thing to have. I mean a new car seat for a cup holder? That makes no sense. There are parents who have trouble getting one car seat and a lot of you seem to have 2-3 per child. I don't know maybe it's just me but if I had the money for all those seats I'd just as soon as keep one and give the others to someone in the area who needs it. I know people who buy every new electronic device that comes out just because it's new and "better". Seems the same here
I admit to buying the seat for more than one reason; I purchased the Nautilus to replace our huge Regent , which was not a combo seat. And in our case, it's sometimes necessary to have more than one seat per child- if kiddo has to ride with daddy or grandma, I prefer not to uninstall and reinstall seats in several vehicles. Having a back up seat works for our family.
My DD and DS love the Nautilus cupholder! It's really an awesome design. And I probably would buy the seat just for the cupholder
And there's the "new seat" factor; I enjoy buying new seats. I don't get my hair done, I shop at thrift stores and discount stores (Marshalls, etc) for my own clothing, I only get a Starbucks once or twice per month, etc. Car seats are my hobby, if you want to describe it that way. And I often give my seats away when we're done with them- I recently gave away a Britax Marathon and a Britax Wizard.
Coming to a new community and criticizing the long-standing members for what they buy, saying that they should be donating seats to the needy instead of having mulitple seats per kid is probably not the best way to introduce yourself, btw.
