After being available exclusively to Amazon employees for the past year, the Amazon Go store is finally open to the public. The gimmicky cashier-less store boasts of allowing customers to shop without lines. But ironically, when it opened yesterday, the line to get in was wrapped around the block.

Located in Seattle, the store allows customers to check in using the Amazon Go app, monitoring each customer’s movements and selections using a system of surveillance cameras and weighted shelves. Once a customer is finished shopping, they are able to leave without checking out; the items are automatically charged to their Amazon account.

The store is 1,800 square feet, so it’s similar in size to most convenience stores. And although it may not have any cashiers, it still has in-store employees to stock shelves and provide assistance.

There may have been crowds around the store when it opened yesterday, but that doesn’t mean that it hasn’t drawn criticism. One customer said:

It’s a bit overkill, I think, to replace a checker or self-checkout stand with a hundred cameras that unblinkingly record every tiny movement. What’s to gain? 20 or 30 seconds of your time back? Lack of convenience has hardly been a complaint for this market — it’s right there in the name: “convenience store.”

What do you think? Once the novelty wears off, will the store continue to draw customers? Or will people miss the personal interaction of having an actual human being check them out?
