Whenever I need my student's attention, I ring the bell once and by the time the tone is over, they know to be looking at me for whatever instruction I need to give to them. I have had this bell for several months and have had zero problems. I would definitely repurchase. I highly recommend."
Bought this when I first got my house and thought it would be a temporary thing, however, here we are about 3 years later and this is still going with the original battery. You can't beat the durability and ease that comes with using this product.
This has worked out great for our office. My receptionist can't always be at her desk and now they can hit the doorbell and she can feel it vibrate even when she is in the mail room. It works great and we have 22,592 sq feet of office space and it rings anywhere she is.
Ordered this for my mom to use and "buzz" for me when needed. She recently moved into my home under hospice care and needs assistance in the middle of the night with using bathroom. She keeps button next to her bed and I wear vibrating pager on my waistband at night. It has worked like a charm each time. "
