After the massive Galaxy Note 7 global recall over exploding batteries, Samsung has now started sending out replacement units to customers in the United States.

The Samsung Galaxy Note 7 has been the talk of town recently, with numerous reports of exploding batteries piling up. Samsung has recalled the device worldwide, promising to fix the issue and send out replacement units as soon as possible.

In the meantime, the company even rolled out a special Galaxy Note 7 IMEI tool so that people can check if their device has a defective battery that might explode. Those who have yet to send in their Galaxy Note 7 to get a safe replacement are advised to do so asap.

We recently heard those replacement units would start shipping by Sept. 21, and it now seems that they're already on their way to U.S. customers.

Reports are starting to show up on Reddit, revealing that Best Buy already has a batch of Galaxy Note 7 replacement units. Customers have received emails that their replacements are now available, albeit this availability seems to be limited to Best Buy stores at this point.

Nevertheless, other retailers and carriers should get the safe Galaxy Note 7 units soon enough as well.

Galaxy Note 7 owners who purchased their device from Best Buy, meanwhile, might want to go pick up their replacement units sooner rather than later. Best Buy said it will offer the replacements on a first come first served basis, which means it will not be handing out the safe Galaxy Note 7 units by order of purchase or anything like that.

It's likely that not all Best Buy stores across the country will have replacement units at this point, so you might want to check with your local store to see if they have safe units in stock before heading over there.

Judging by user comments on the Reddit thread, some Best Buy stores have a few replacement units on hand, while others are still waiting for the shipments. One user notes that the Best Buy rep they talked to said they can pick any color for the replacement unit, as long as it's available.

Depending on available stock, those who preordered the new Galaxy Note 7 as part of the recall might ultimately end up with a different color device than they initially ordered, since the replacement units are going on a first come first serve basis.

We'll keep you up to date as soon as we hear more, so stay tuned. If you already got your safe Galaxy Note 7 replacement from Best Buy, drop by our comment section below and tell us about your experience.
