I got this for my Dad in assisted living. It is easy to use, but a pain to program because you essentially need three hands, one for the phone, one to set the number, and one to flip over and press the programmed button (ok a little exaggerated). Since the dial tone at my Dad's facility would conk out fairly quickly this made it difficult. Plus, as noted, it does not remember numbers when unplugged. It works for him though.

The product works as expected. The buttons are big and it's relatively easy to use. What could make it bettter? Having a printable template that I could download from a website and put into MS Word or something like that. Also, if the device had battery backup that would be pretty nice too.
Overall, I like the size and function.

The instructions are a bit vague... at first I couldn't get my set numbers to save, but then I realized you have to hear the dialtone before you set the number. The instructions say "remove the receiver", but I was using a cordless phone, so it wasn't giving me a dialtone. Also, you have to remove the plastic pieces and "blank faces" that are already on the dialer before you put your own in the slot. Other than that, it functions perfectly.

This is a great concept, but did not work well at all for my grandpa with dementia. He could not grasp the order of how you have to dial with this thing. You have to pick up the receiver first and then wait for a dial tone and then push the button. It was too much for him. We put it away after only a week of him trying to use it.

Works GREAT for a person affected with poor eyesight, diminished memory or just people with "FAT FINGER" syndrome. Very easy to program and the programming buttons are covered with a slide door on the underside that can be temporarily locked with tape to keep unauthorized fingers from messing up the stored phone numbers. There are 12 memory buttons that can have a picture, hand written words, typed words or any other communication method to show who will be called at the touch of that button. Each button also comes with extra plastic covers that protect the communication method you elect to use to keep the picture or paper from getting damaged or stained. The picture shows three buttons for POLICE, FIRE or AMBULANCE but if you just want to program one button for "911" or a regular phone number such as some small towns still have for ALL emergency departments and have 11 other buttons for other things that also works great. My mother-in-law was constantly losing phone numbers or miss dialing the ones she could find but now calling the grand children and friends just got so much easier.
