One suction cup for ErgoPlay Tappert or Troster supports
For complete cup replacement, Tappert Supports require three cups. Troster Supports require four cups.
NOTE before buying new cups: If your cups don't seem to be working like they used to be, try soaking them in very hot water for a minute or two. This may revive them.
Great replacement for my worn out accessory. And great company overall!
This is the best suction cup I tested for my guitar support. It's difficult to find but XGuitars has it. Thanks
