Review on 🕰️ 4.2 Inch Alarm Clock Radio with Bluetooth Speaker, Dual Snooze Clock, USB Charging Port, AUX TF Card Play, Thermometer, Large Mirror LED Dimmable Display - Perfect for Bedroom, Kitchen, Hotel, Table, Desk by Wendell Mitchell

In addition to the normal alarm functions (alarm clock, snooze function), I had the following requirements: - alarm sound from SD card - ability to play music from SD card OR USB - storage - sleep function ( Play music, like rain for a certain time, eg 45 minutes) - Adjustable alarm volume - Slow increase in alarm volume So far all functions work (which hasn't happened with other alarm clocks I've tried). Alarm 1 is set as a regular alarm for the week and plays my own alarm music from the SD card. The alarm volume increases to the maximum volume that I can adjust to my liking. Alarm 2 can only be set temporarily. This means that it cannot be programmed to turn on regularly during the week. Each alarm must be intentionally set. Playing rain music from a USB stick as a sleep aid works flawlessly. The sleep function stops the rain music after an adjustable time (15, 30, 75 or 90 minutes). Bluetooth works. The radio works. The speakers are good for an alarm clock, but not for Bluetooth speakers. Bad sound quality, no bass. However, a good speaker was not my criterion. A backup battery helps maintain the alarm and time in the event of a power failure.
