I am a tennis instructor. The lines and corners stay where placed. They are unaffected by the wind or if stepped on.

I used these on a dusty gym floor they worked great but got dirty so I threw them in the washer with a towel and they are good to go again. Used them on the lawn also. They moved a little but still served their purpose. We aren't that technical....just out to have fun and get exercise.

These work well on smooth play surfaces such as indoor courts, tile floors We found that placing them upside down, with the smooth side down instead of the grippy, nubby side down worked well for very smooth and clean surfaces such as the tile floor. if the floor has any grit or dust, that will stick onto the pieces and will need to be cleaned periodically so the smooth side makes better contact with the floor and is less likely to be kicked out of position. It's a great timesaver in setting up court boundaries versus chalking or stringing where permanent lines cannot be painted.

Markers are easy to use and stick pretty well on the indoor court. We have not used them on an outside surface so I don't know how well they would work.

used for pickleball lines on tennis court....even with 2 sets still difficulty discerning lines....

To me, they are what I expected. Meaning, what you see is what you get. They look just like the photos. They do have some weight to them and that keeps them positioned nicely with absolutely NO concern about wind moving them. They are also durable and rubbery feeling so if you step on them you can feel confident you won’t damage them or slip. Nice.

awesome quality great for the clumsy kids!

In my community we need to use the tennis courts and the tennis players are not too happy about this. We used to tape the courts for Pickleball but when we started using the Gamma Court Markers we could set up and take down in no time. This made for happier tennis and pickleball players.

Easy to set-up.
