Review on Wake Up With Ease: ANJANK Extra Loud Dual Alarm Clock With Bed Shaker And USB Charger Port For Heavy Sleepers And Hearing-Impaired by Jennifer Corbett

Really works well for hard of hearing; I always had difficulties with alarm clocks due to not hearing them most of the time. This one, between the volume of the alarm and the vibration, works really well. When alone, I can use the alarm and vibration; when not alone, the vibration alone works great. The only set back and reason I didn't give it 5 stars is the writing on the buttons. The clock is black and the writing is dark green, very hard to see/read. If you save the instructions, you'll be fine; but why they chose dark green for the writing on the buttons is beyond me.
