Is the rubber ball somewhat gel-like or too hard that it makes a thud sound or scratch hardwood floors when thrown across the room?

The rubber is soft & pliable. We have hardwood floors & they did not leave any marks.

It is a hollow rubber ball with little nubs on them. I throw them inside for my dog all the time and have never left a mark on anything. They don't make a loud thud when they bounce off of the wall or floor but they aren't completely silent. I suppose if I lived in an apartment with paper thin walls I would avoid bouning them off of common walls but I wouldn't worry about bouncing them off of anything else. They make less noise than a tennis ball.

These balls are a bit firm, not too soft. I wouldn't think they would scratch wood as they bounce off. We play with these outside at dusk anyways. Lots of fun.

They are hollow rubber/silicone... I have hard wood through the house and the only scratching comes from the dogs nails...

The silver "pad" around the trampoline, like you see in the picture, is what I think they are referring to. There is no floor pad/mat that came with mine. I also have it on carpet so I don't have a noise problem.

It's sort of in between. It's rubber but not super hard either. It's soft rubber.

The wheels are very smooth rubber and have ball bearings. I have not yet noticed any audible sound from them after several uses. However, I am usually shooting events, so any wheel noise would be inaudible anyway, but rolling it around I can't hear anything in a quiet room.

We have never noticed any squeaking after using it. That has been our experience, I would imagine it depends on the floor and the quality of the floor.

I bought this for my grand niece for Christmas so haven't used it yet. It appears to be a soft plastic bristle and I don't believe it would scratch the floor.

The base is metal with a hard plastic encircling the base and separating the metal from the floor. It's hard plastic, not rubber like, so it might scratch a hard wood floor.

Well the wheels are made of hard plastic, so it is going to make some noise. I have tile floors and it isn't loud in my house so you should be ok if you don't go to fast, the slower you go the quieter it will be.

The bottom is a rubbery (not slippery and not squishy) feeling plastic (if you knock on it with your fist it's a hard material). I use mine on carpet but my wife uses one on wood floors and it doesn't slide or leave scratches.

I used this treadmill on a carpet with a treadmill map beneath it. The noise I mentioned in my review was quite loud in the house if I did not shut the door. Once I shut the door, the noise was not that bad. I am not sure if the downstairs will hear the vibration if the floor is wooden floor.

Hmmm... probably, it's pretty sensitive. I haven't actually tried that but I do have hardwoods throughout and I can check.

The balls are made of regular material. Yes they could cause damage to floors and windows.

It is flexible like a tennis ball just a little firmer. It bounces nicely but is a little too heavy for my 7 lb. puppy. She loves chasing it down the dark hall though.

I purchased the mat to protect my hardwood floors. I haven't noticed any vibrations or noise as a result of my treadmill. That may be due to the fact that I have a brand new treadmill.

It is hard plastic ....I don't see any damages to my wooden hard floor . It's no scratch at all.

It's a hard plastic. It won't scratch a hardwood floor, but it may leave scuff marks. It doesn't really slide. But you could easily push it on a wood floor

It runs smooth on wooden floor. In fact our floor is wooden! No scratches so far. But it will be louder on wood than on carpet!
