The Black Hole is a solid rubber disk that is concave on the bottom, tacky to the touch when clean, and sticks to most but not all (clean) floor surfaces. The cup for the tip is 5/8″ in diameter and 3/8″ deep which only matters if you keep a rubber tip over your sharp endpin tip. There is a hard plastic liner to protect sharp tips (like New Harmony’s) from piercing the rockstop. Remember to renew the tacky surface by a warm water wash when dirt and particles stuck to it prevent it from slipping.
Artino’s SP4W rockstop has a 3.5″ diameter round wood resonating chamber, 7/8″ thick with non-skid backing. The web strap extends from 24-43 inches with a loop on the end, and is detachable so the Artino can be used with or without strap. The cup that holds the endpin is plastic lined to prevent sharp tips from penetrating. If you keep a rubber tip over your endpin, be aware the cup is just over 5/8″ in diameter and only 2mm (less than 1/16″) deep. The effectiveness of the resonating chamber will vary with a room’s features and acoustic properties. Weight 2.3 ounces.
A new grippy rockstop from Switzerland has a very thin profile. It weighs 1.4 oz and is 3.5″ in diameter. .A rigid holder fits inside a polymer-based jacket, and is supposed to hold on any surface, including ice. Being in South Carolina, I don’t expect to be able to challenge this. Stay tuned for comments, as this is a new item here.
Artino’s resonating chamber measures 6″ across the top, 7″ across the bottom, is 2.75″ wide, and 1.5″ thick. The webbed strap adjusts from 15-24″, connecting the box to the chair anchor. Effectiveness of the resonating chamber will vary with a room’s features and acoustic properties. Weight 9 oz
