Dycem Floor Protection Black Hole

Probably the most interesting item in that price range. Good fabrication and good grip overall. It's small size makes it easy to store in the small pocket inside the cello case or in a bag.
Especially efficient on wooden floor, it however needs to be rinsed regularly (after a long rehearsal for example) to prevent dust to gather too much underneath, which can then make it less stable and more slippery (like any other floor protection of that sort).
Would definitely recommend it to any professional cellist looking for something easily transportable and usable everywhere.

Good quality, serves its purpose! Although, the item I received I may say as if it has been used there are some uneven and deep scratch in the front part as if it was poked. It doesn't slip when used in tile area!
