I guess I just don't understand the features well enough to see why it would be a huge seller. I mean, I have a Honda, so the rigid LATCH means nothing to me -- Honda has a 40lb limit for LATCH and I can't use a booster legally until 40lbs, so remind me why I'm excited about rigid LATCH on a booster? I definitely would love it for a convertible, but for a booster that I can't use until the weight limit for LATCH is exceeded in my vehicle d/n really rock my world. Having a booster that LATCHes is a convenience feature -- so I don't have to remember to buckle it when not in use -- not a safety feature, so rigid vs flexible LATCH isn't a huge deal.
I don't have plan on having my kids ride in a dedicated booster when a recline is an issue, so the recline isn't a huge sell for me either.
For that price, it would be great if it had a harness and competed with the Frontier and the Nautilus. But, without a harness and convert to booster option, I'm not sure I see the appeal to the average buyer.
Well, other than the cute covers.... LOL.
I am curious, though.
