Sent to a relative out of state, this one wasn't as well received as the cardigan style (from the same company) I sent, but at least it fit properly and she did get to wear it a couple of times.  She reported that the light-up feature was hit/miss, she could never predict when it was going to start flashing and, of course, when she really wanted it to flash- it usually wouldn't.  Since she is elderly, it could possibly have been user error.
