My only fear would be the suction cups failing and the nest crashing to the ground. Are the suction cups really sturdy enough to stick?

I never got the nesting box up this year but everything else I had with suction cups stayed put so I don't think there would be a problem. Too much activity near the window this year. Will install next year.

This one does stick, however, the backing is not a one-way backing. So, the birds can see you all the time and after all this time of having it................no birds nest in it. Sad.......

It really depends what type of glass you are sticking it to. Some glazed glass, like the kind that is coated for sun issues or the double pained glass for insulation purposes, they really don't stick well to. Plain regular glass they work very well on and not heavy coated glazed glass they work on. You can always put a small loop hook on the top and a wire through it and hook it to the top of the window sill and then the suction cups just keep it stable.

The posts seem pretty sturdy. The only movement is the whole unit wobbles when my 18 Lb boy launches himself and it doesn't look like it is going to tip over. I got this one after checking out a mainecoon lovers website. It was recommended.

I would say that they are at least as stable in the holder as any other type, perhaps more so. I've used others before and you have to be careful will all of them. I think these are pretty stable but I found that you do have to be sure and push them down into the base firmly to be safe. Hope this helps.

I never expect suction cups to hold forever. Always check before putting full weight on it. This is much better than most. Slipped down one time in three months, but did not completely release. I just released and reattached. It is easy to do. I would recommend as long as buyer realizes that suction bars must be checked periodically.

They appear to be very stable and could handle stacking 2 on top of each other. I only have one, but would not hesitate in putting 2 on top of each other.

Sarah, they are very strong. Our turtle is 30 years old and probably weighs 5 pounds and it holds solid. We are cleaning his tank on the weekend so we will see how easy it is to remove them. In the past we always took the dock and the suction cups off each time we cleaned the tank. I think we will be able to remove the ramp and leave the suction cups in place. Our pet loves this ramp so much that we wouldn't do without it now.

The rubber cups? took the paint off of my ceiling. I have hardwood floor and the poles aren't as sturdy as I want them to be (still wiggles a bit when I shake it after assembly); sturdy enough but not completely stable, don't think it'll fall unless someone leans on it or kick it. I don't find much use for the curtains since it doesn't cover the middle section. Currently have these poles in an L shape to save some space. Overall I'm happy with my purchase!

No, they are fairly stable. I stack mine 4-high, and as long as the floor is flat, they are stable. It's a clever design - flip the handle to the back and they nest, flip it forward and it forms the base for the next one to stack on.

I've had mine up in the the tub for months now and they have never come down. As long as it is on a flat, not curved, surface you should be fine. Very strong suction

It is semi secured with four small suction cups. I think it's pretty stable.

No, don't seem sturdy enough. Would require good anchors top and bottom for sure.

Make sure window is clean for suction cups to stay put. Mine held on very well until a squirrell sat on and squeezed into it one too many times. It didn't break though. Just clean the surface before sticking it on.

I believe it is sturdy enough. Mine is against a wall, but have to pull it out to sweep under it and it's never tipped.

Yes. Simply moisten the suction cups and press firmly. It should stick for some time but may, as any suction cup mount will do, become loose when the moisture under the cups dries out.

I would say no, they are not tough, they tend to keep the shape of any heavy object that's placed on top. Plus they are very slippery once they get dust under them.

It does come w/suction cups, so if you could get them to stick very well you might not have that problem. I have mine on tile (uneven) and it moves every where.

I have found it very sturdy. I have two long seed feeders, a suet feeder and a water tray and have had no problems. Even in high winds while the feeders sway a great deal, the pole remans strong.
