Yi’s original action cam is a longtime reader-favorite, and one of my personal favorite gadgets to boot, and you can pick it up for $55 from Amazon with promo code VDF5CJDF.
Update: Scroll down to the special offers and find the one to get a free extra battery. Just hit the button to add both items to your cart.
This model doesn’t shoot in 4K, but it does feature 1080/60, and the footage and photos it takes look fantastic. You can even control it wirelessly with your phone, or transfer your captures over Wi-Fi for instant sharing. This was briefly available for $60 on Prime Day, so today’s $55 deal is the best we’ve ever seen.
