yes it is very applicable to all circumstances and space saving requirements for the hard wooden floor living room.
I only dropped the rubber coated dumbbells once nothing happened , but the regular iron 55lbs dumbels of peace, once (only one) when I put one down on my office chair after front squatting and the chair recoiled like it was spring loaded, I failed to catch the weight in the air and it fell, I was also having the other dumbell still on my shoulder and the weight in the backpack or I would have been able to reach out and grab the fucker.
I washed the floor off with a rag so there is no discoloration.
