BRIC's B|Y Expandable Carry-On Luggage 21"

Im in the US and is this a good brand and most importantly, the size is slightly wider and fatter than the carry on sizes for frontier, spirit. Its marked as a 21" carry on. Will this be of a concern? I see other brands are also slightly bigger. amatuer traveler.

Im using my company points so price is no problem. I see its not made by ABS which is why I would like to spend a bit more. Love the mango color tho.
