Amazon has reduced the price of its Ugreen Bluetooth Tracker 4-pack bundle by 40%, bringing it down to $30, making it an easy way to keep track of essential items on the go. The tiny trackers can be easily integrated into your purse, bag, or luggage, and even attach to your keys or water bottles. They play well with both iOS and Android devices, so users can check their items' whereabouts through their phone. The tracker ring can be made to locate items near or far away, or be directed to their location on a map. The battery lasts up to a year and can be charged via a universal USB-C port. However, the discount ends soon.
