BlackBerry Passport sales are doing much better than the initial criticisms about their unique design might have let on.

CEO of BlackBerry John Chen claimed that it took only ten hours to sell all the BlackBerry Passport units on BlackBerry's website as well as on Amazon when it first launched, according to International Business Times.

Preorders reached 200,000 for the next available round of units produced.

The Passport is BlackBerry's newest device after a two-year hiatus, and has a unique square shape to allow easier reading of documents for those in the business industry. In addition, BlackBerry has kept their traditional physical QWERTY keyboard instead of copying other new smartphones and offering only a touchpad keyboard. But the keyboard does operate with certain touch functions.

BlackBerry said that it has received 4.8 out of 5 stars on Amazon just six days after its first release.

The phone is on sale on the company's site for $599.

"The traditional consumers want apps on a cheap device. The perception was that BlackBerry does not offer the apps they want. We have fixed that by pre-burning the Amazon App Store in the new OS and giving them access to 2,00,000 top Android apps," Sunil Lalvani, Managing Director of BlackBerry India, told IndianExpress. "This is an interesting first step in our new roadmap for the future. This indicates that our device portfolio continues."

And sales for the Passport are strong for the Canadian company, but cannot be compared to iPhone or Galaxy, according to the Globe and Mail.

Jack Gold, of independent J. Gold Associates in Northborough, Massachusetts, said, "It's not a fair comparison, given [BlackBerry is] focused on enterprise users.

Gold said that the sales for BlackBerry are significant, though, and should increase when AT&T starts carrying the phone.
