I bought this product with the expectation of it lasting a lifetime - or at least for a long-ish time.  Which, I guess, depending on your definition, it did.  I purchased mine about three years ago and was very happy with the product.  The weak link, however, is the connecting pin which is now bending out of place and loosening the clip's holding power.  When new, the clip would securely hold one bill or twenty (plus cards!)  Now, anything less than a short stack will slide out.  For someone that likes to change frequently, I'd give a strong recommendation for this product.  If, like me, you prefer to find something and stick with it for as long as possible...well, like I said, it's good for a few years.
