It’s hard to slide it under a shirt. There are too many hooks and rough spots that snag the fabric. It’s also hard to grip; the handle is thin and slippery so putting it where you want it, especially with arthritic fingers, is challenging. The dog tag jingles, which is not what you want to hear in the middle of the night, though it’s easy to remove. My husband likes it. It’s not my favorite. Sorry.
