Share 'Eco Star vs. Echo Star'

Is there a difference between the Eco Star Plastic by Innova and Echo Star? I recently purchased a Eco Star Groove and then more recently I bought an Echo Star Wraith. On the website I got the Groove from it listed it as Eco, but the Wraith had a sticker on it that said ECHO. Just wondering if it's two different types or just a misprint by the Groove.
