Review on Versatile NOAA Weather Radio: Portable AM FM Shortwave with LCD Screen, Auto-Scan, SOS Alarm, Sleep Timer & Headphone Jack - Ideal for Home and Emergency Situations (No Clock Function) by Harwinder Duong

I bought this for a sleep timer. Although the manual says it can be set to 15, 30, 45, 90 minutes, it only sets it to 90...which worked for me. The sound is normal, loud enough, picks up stations with no problems. It requires 3 AAA batteries, and as long as the battery gauge is fully charged, it will play normally, but once the gauge is reduced to 3/4, it will play about 10 minutes (or less). Works for me, not perfect but good enough.
