RockStar Concepts Door Stopper Rubber Stop Floor Wedge Holder Doorstop | Premium Quality Heavy Duty Non Slip All Surface Decorative Security Doorstopper | New Larger Taller Stops (3 Pack - Gray)

Good quality; these things should last. Fair price, and I love the little mounts they come with. The symmetric design works equally well if you flip it over (unlike traditional doorstops) so it's even easier to shove it in place with your foot.They are thinner than usual doorstops, and if your carpet is think and/or your door has a wide gap under it, someone with enough strength might be able to push a closed & stopped door open without as much effort. That honestly might be a plus (you aren't using the doorstop in place of a lock for security, are you?) but it's the closest thing to a "problem" with these.

I bought this to try under the door of my classroom and while it might hold the door in place from a gust of wind, thats about it. It slides right along the tile floor with the door. Not that I expected a full security measure, but I thought it might hold a little firmer and offer a little resistance. It is a well made product and I'm keeping to to hold my classroom door open when the windows are open.

My product arrived quickly and matched the description in every way. The door stop works on carpet and tile. I bought it to prevent a door from being opened as a security measure for a school. This is the best product I have tried for that effort. It does not completely hold the door shut (I don't believe any product can against great force) but does offer a tremendous amount of resistance so it acts as a deterrent. Would recommend.

I have hardwood & this product does not work on this type of flooring. I NEEDED door stoppers that will work specifically on hardwood. Not a bad product for carpets.

I love this door stopper! I was used to door stoppers being flimsy and cheap. This one is the opposite. The quality is very sturdy, capable of holding back heavy doors (example: my office). It also seems non slip as I've had that problem with previous door stoppers. Bottom line: this is a far superior product in terms of quality and durability. very happy with this purchase!

Not great...they’re too hard to be pliable at all, so they don’t stick to our wood floors (like the old-fashioned brown ones would). So for our situation, they might keep the door in place as long as there isn’t any force on the door at all, which defeats the purpose.

Works great on my front door which is about 2" above the floor surface. I put one on top of the other, easy to forget since there is no up or down side. The holder works great, put on the baseboard in the corner next to the door, and both stoppers fit nicely against the wall.

Very disappointed in performance. I tried using them on a waxed tile floor, they are marginally effective. On carpet they would be Great, not so much on a slippery floor.
