This is my third order, hand these out to people who come for a ride on my boat. Everyone appreciates not losing their hat while underway! Works well, would recommend these for holding on to your hat!Really love these clips. Made out of a soft material and will not break like other hard plastic clips.Not very strong. Not worth itPurchased these. Then saw the chums version. Chums was far superior. The clips are plastic, and do not have very good grip strength. I feel if my heart tried to blow off on the boat these would come unclipped.Bought these to hold on hat while on motorcycle. Awkward length for its use, and would prefer if it was more elastic. It was cheap so I didn’t return, but won’t buy again.These are PERFECT for face covering masks. Connect the plastic clips to the ear loops on your mask and hang the strap behind your neck.. You can remove your mask but have it right under your chin so it is easy to put back on instantly. You don't have to handle the mask as much - there is no storing the mask in a pocket or purse. Absolutely great for multiple stops in the car. You always know exactly where the mask is, and you are far less likely to forget it.Invaluable out of doorsI purchased these to use while sailing to keep from losing my hat overboard (again). As you can imagine it can be very windy and having already lost many hats overboard when the wind blows them off my head I thought these would be a great way to avert more lost hats. I was hopeful these would solve my issue...I was wrong. Luckily, I tested these clips on land before using on the water. My test consisted of attaching the clip to my hat and shirt collar and then pushing my hat backwards off my head. Well, these clips failed to keep my hat from hitting the ground. The problem is that the actual spring loaded clip just doesn't have enough grip strength to hold onto the hat (just a regular baseball cap). It just slips out with just the force of gravity pulling it down. Basically, it worthless for what I need it for and I can't imagine it working for any application since it fails with minimal force applied. I will be returning these and looking at other options.
