I used these for outdoor gazebo legs. They worked great and hold the legs down very tight.

Worked really well but a little hard to tighten straps.

Purchased two sets of these to tie down a couple of motorcycles in the back of a toy hauler.  I only needed short tie downs and most are long and you have lots of extra length.  These worked great.  Just push the button and the slack in the line retracts and then ratchet it down.  When not in use, just push the button to retract the whole line for neat and compact storage.  I love them.

Found these after a buzzfeed article which featured the product. I was skeptical, but they worked so well. They have a rubber lining on the top and bottom to stay in place against your skin. I would make sure that you accurately measure your legs to make sure you have the right size. I could see these not working if you do not find the proper fit. I will say that if you have a booty, they will sit a bit lower on the back of your leg, as they will roll if you pull them up too high. They feel strange, sometimes like they are even falling off. But I found they stayed in place all night and I didn't have to worry about them. Prevented my legs rubbing together perfectly. I was not super active in these, so I do not know how they would do with higher impact movements (like dancing). But walking around in them was perfect. I am so excited I found these!

Purchased these to hold down the large rug I put outside the door of my motorhome -- they worked great - the wind blew very hard on our last trip and the rug stayed put.

These worked much better than I had expected.  I use them under an ottoman that needs to be moved out of the way to create room for our XBox Kinect games.  We just leave them under the legs and move as needed.  The foam tops do a good job of keeping the legs in place under the disks. The smooth bottoms provide the perfect amount of resistance vs weight to easily move when you want it to move, yet it doesn't slide when you put your feet up and want it to stay in place.

Note:  The ottoman we use these for is a relatively light piece of furniture.  I'm not sure how these would perform on a larger/heavier piece because I haven't tried, but there's no reason to believe they wouldn't work just as good.

These worked very well.  Take your time to assemble them correctly or you will spend a lot more time fixing them.  I used the to store clothes on a closet shelf and they held up to the load I needed.

Solid and they work great. Have to re tighten the legs here and there. My Dancers like them. I also have the lighter bars from Vita Vibe and they also work great.

The way you had to wear it was NG. I pinned the legs to the shirt and that worked great.

They did a great job to secure some deer block netting.  I didn't pull them too tight and didn't have any break.  They are pretty tiny.

I used them to hold our scuba regulators for a trip to Roatan. They did a great job protecting them. Well constructed and appear to be sturdy.

First off, these are super cute and the color is really nice (I have them in dark green). They definitely do their job well. One problem I have with them is that the legs are very tight - I have slim-to-normal size calfs and they're still tight, to the point where they actually push up my pant legs when I'm putting them on. But that's not a big deal so otherwise they're pretty good!

Worked great - hammered in to legs of wooden table chairs.  Very secure and provide excellent floor protection.

These little guys work great and held our stockings well. I would highly recommend these for anyone with little ones as they don't have a heavy weight at the top if they get pulled down.

Once they are locked down they work great. Be careful when unhinging then from your work, if you aren't careful, they can tear out your wood in the pocket hole.

these worked great for me.  if you do not tighten them down the screws will start to vibrate and back out. i'd buy them again in a second.  easy to use, and re-use.

Work great for the boots I have, and hold a tie well.
