I've used various versions of shirt stays over the years (job requires a suit every day) and these Y-style shirt stays were by far the most disappointing. I've been using this Rotho product for less than two weeks and the fasteners have already broken off. Additionally, the fasteners detached from the shirt multiple times a day (far more times then other shirt stays I've used). Having to take the time to re-fasten the device is quite the chore during the middle of the day.I tried adjusting the tension on the shirt to see if the fasteners would grip the shirt more securely and stay fastened for longer periods of time: this adjustment proved unhelpful as I still experienced the same disappointing results.Seriously consider another brand/product.
