Review on ⏰ Sonic Alert SB200SS Alarm Clock: Wake Up Vibrantly with Battery Backup and Multicolored Display by Valerie Harper

Generally a good alarm clock. Other reviews mention that it's a bit finicky and I agree; Even with a 9 volt backup battery, I seemed to have to reset the time and alarm after every power outage. The mattress power shaker cords can also come loose, but duct tape can fix this. The clock itself is large, easy to read (even with short-sightedness), the light/dim switch switches from very bright to tolerably dark. The volume is LOUD and the pitch can be adjusted for frequencies where your hearing is more sensitive. The shaker is pretty strong; you wake up. I've been using it for 8 years until it stopped being alarming - both noise and shaking. I'm not sure why he died, but now it's just one o'clock. I came across this while looking for a replacement so thought I'd add my review.
