This item was used indoors only when my child was playing youth baseball, so it's relatively clean. There are some minor scratches and slight rust (?), due to aging, on the frame. After accidentally dropping it on the floor once, the arm seems to be slightly warped, and it requires a little force to insert it into the hole when adjusting the height. However, I didn't find it particularly bothersome, and I used it without any issues. My child also said that there were no problems with stability during use, such as wobbling.
