These are good, but hopefully somebody makes their millions figuring out a way to keep them from sliding down off the dogs foot.

My 13 year old son likes them. However, we have to adjust them every week because they tend to loosen up.

Beautiful set of bars, but irritating that they don't stay tightened down. Surely they should be able to fix that.

They did not work so well in tight spaces, to get these in place you have to stretch them to about 6"

really cool but don't stay stuck long, constantly having to push on them where they start to fall off.

These are awesome IF there is no tension put on them by having a gap between the bottom of your fence and the ground.  If there's in more than a half inch or so, though, you won't be able to secure them properly in the ground.

They're a but tough to get on, but that's good because you know they'll secure the weight.

They were a struggle getting on the first couple times, but are worth the effort.  also they stretch out a bit and get easier to wear.

Make sure you buy the correct size, mine are to large and they slip down. They work well for a bit until they fall. If you have the correct size I'm sure they would be amazing!

THESE DON'T COME DOWN QUIT AS LONG AS THEY SHOW IN THE PHOTOS. WITH THAT SAID, THEY ARE JUST O.K..

I bought a bag of these to secure a seat cover to a recliner.  They work as advertised.  However, the heads will quickly work loose if they are under tension/load.  The heads will pop off so you should plan on replacing these periodically.

I would definitely buy them again.  I just want to alert you to their limitations.  They are not perfect and won't last forever.

A great item but do not let it fall more than 4 feet  or bye bye .

They don't fit on the stakes tightly, so they keep falling off.

They were fine and dandy for all of 30 seconds , then they started slipping down and don't stay in place.  Would have been nice if they were adjustable!

They are really nice at first but if you put them in a large section, they will slide around after a while. I laid down some carpet stopper and it was fine
