Suction Cup Sign Holder for 8.5 x 11 Inch Campus Maps and Announcements in Schools Colleges and Universities Clear Acrylic Double Sided Window Mount Sign Frame by Marketing Holders

Received this several days ago for primary use inside my car for rideshare service (I don't like those removable stickers).So far so good. Attaching the suction cup to the plastic thingy can be a big pain in the behind but was able to attach those suction cups. One trick I found is to insert the suction cup and turn, while pushing, the suction cup clockwise.The plastic holder thingy seems to be sturdy.This is one of the less expensive signboard holder I have found on Amazon.

I purchased this for my home office door but the spacing in the suction cups happened to fall where my door crevice is located. It seems like a good quality product but i was unable to use it because of my door shape. When I tried to return it even though it was prime, I was informed that it would be at my own expense. So now I am stuck with it. It would cost me almost as much to return it because of the packaging.It seems like a good product but be aware that there are NO RETURNS.

There's nothing exceptional about this. But it works, and that's more than I can say for any other option currently being carried.After buying and using all 3 of the kinds of glass mounting 11x17 poster frames, this is the only one that will stay stuck to the window!! All the other options have consistently dropped / cracked / one suction comes loose. I've literally thrown out over a dozen of "Source One" branded options. And yes, I put them on properly. The competition is almost exclusively two suction cup design, and with the weight of the acrylic and the distance of the cups, it tends to sway back and forth- meaning it will not only fall off almost immediately when put on a door, but any window that isn't in a perfectly quiet, undisturbed space... even loud music will knock them down. But obviously, the reason you had bought this to begin with is to advertise something, most likely in a place where people will see it- meaning doors, front windows, and areas that have high traffic and might be susceptible to a minor bump here and there. So, if you buy any of the two suction cup designs here on amazon- you are asking for a headache. Moreover, the two cup designs are shipped really poorly- a couple inevitably don't even arrive in one piece from UPS. I've literally purchased every 11x17 window mounted sign option on amazon, and this is the only one I will ever buy again.I mounted on the most high traffic door to test its durability, and it's still up there 6 weeks later. That's a miracle, comparatively.It may be more shipping, it may not be perfect, but I am highly doubtful you are going to find a better option. So, if you are looking at this, buy this one first and spare yourself the fact finding process I had to go through.Tip for use with these: Use a small piece of scotch tape to keep the poster sleeve from rocking around, or any kind of a clip that will keep the two panels together. That's the only change I would personally make to the design if I could. Also, take the time to fully clean the surface before you stick the suctions, and make sure it's even and where you want it. If you don't do it right, you are asking for trouble as if these things fall on anything but a mattress they are goners. The acrylic is quite brittle.

By far the best option I have bought for this size and this type (suction cup vs. screw mounted). I had purchased two other types of this sign which disappointed both in the suction cups being made of cheap material that would not last and the plastic being thin and brittle. This signs has weight to it as its thickness seems to be better than others and the suction cups hold strongly.To be fair, I have only been using them a couple months, but they appear to be holding up nicely and I anticipate they will continue to last. Definitely worth the money (they are a little more expensive) as you get what you pay for.PROS:Strong suction cupsThick plastic built to lastCrystal clear plasticCONS:A little more expensive (worth it, but still a con)The finish on the plastic can cause a lot of light reflection dependent on your lighting situationOverall, an excellent product that I would recommend to anyone needing an 11x17 suction cup sign holder.

With Covid -19 I don't know what our office did without this! Our signs are changing all the time and we don't have to worry about any tape on our windows. We have two one on each door they make life a little easier.

We got this to hold our camping permit in the trailer window when at campgrounds. Genius! Just the right size and the suction is excellent.

Arrived as expected. Works well for what we need. Easy to assemble. Suction cups are durable and so far, no problems with the plexiglass holding up over constant interchanging of posters

Sturdy plastic. Perfect for offices, gyms, apartment complexes. Easy to clean and insert flyers.
