I like your products alot, looks really interesting. BUT (and im not being in any way rude, may intention is only to crticise constructively) you should take the poplarity bar away until some of the items have a better rating...so keep it active but invisable to users until the ratings are higher. then suddenly pull it out of the bag when the items have ratings that are worth showing off....
otherwise, well it looks like all items are unpopular
goodluck!
