One of many concerns about neodymium magnets is when they lose strength as they age. Actually, only very little in their strength is lost after a while. NIB magnets stay in keeping with their trustworthiness of being the strongest and many permanent magnets available, so any strength lost caused by age is pretty negligible. If there are no factors which will obviously adversely affect their magnetism, for instance contact with high temperatures that has reached over 80 degrees Celsius or physical damage (e.g. as long as they were attempt to be soldered, welded, or machined), then only about 1% with their strength is lost on the ten year period. That is virtually unnoticeable unless an individual has a very sensitive tool in measuring the magnet's strength. Compared to other weaker magnets that lose a little their strength when they are stuck attracting or repelling positions along with other magnets on the number of years, NIB magnets don't.
