Swallow Static Window Clings Anti Collision Window Decals for Bird Strikes, Glass Alert Bird Deterrent, Stop Birds Flying into Windows, Set of 20

Very difficult to remove the backing. Gave up trying with tape & used a stick pin. So far we’ve had no birds hitting our windows so they’re working. Very beautiful and not too noticeable. Am curious how they will fair when windows get washed.

Love it,they look beautiful and serve the purpose

I followed the directions (unlike, from the sounds of it, the people who gave this item a 2 rating. One didn.t seem to put them on correctly and the other put them on the outside of the window instead of the inside- presumably since he said the birds pecked them off). Anyway, they stick fine and look nice but oh, were they a pain in the ass to get on the window. Why? In order to get them to stick on, you have to take the sheer backing off them (kind of like taking the backing off a bandaid). The problem is that there is no way to get the damn sheer peice off with any ease. There's no "tab" to start the separation process, and it feels impossible to get the two peices pulled apart. What should take 2 seconds ends up being an aggravated 5 minutes for EACH decal. The decals should come on one single sheet- like stamps do- as that would make it easier to pull them apart. Oh yes, and once you separate the two pieces, the sheep part gets all clingy and won't come off your fingers, making for more fun antics. I've just finally gotten them all up. Don't yet know if they are good bird deterrents or not. Here's hoping all my struggles were worth it. Would I buy these again? Only if I could not find something better.

We’ve had lots of birds flying into our windows, so I bought a medley of these sorts of clings from different companies. They all seem pretty similar and work well. I actually have a sheet of this sort of cling that I put up on our other windows for privacy, so I felt pretty equipped for the installation.With the sheet, the worst part is trying to get the cling separated from the backing. It’s on a level with the most stubborn of produce bags that just WILL NOT come apart when in the grocery store. So the reason I’m reviewing this one in particular mere minutes after finishing the installation process is because, unlike the other clings I purchased, this company includes all of the clings on a couple pages that make it SO easy to remove. I have a little collage going on my window so I spent a ton of time trying to remove and prep the various birds and circles I also purchased separately, and then when I got to these feathers it was a nice little sigh of relief and my nerves got a break.So I can’t yet speak to their effectiveness yet, but I feel pretty good about it. I’ll update if birds keep bashing themselves against my window despite the clings. This company also included pretty comprehensive but easy to understand instructions.

I used the three smallest decals on my window. While a little difficult to separate the clear backing from the decal, we followed the suggestion of using cellophane tape on both sides of the decal and gently pull apart the backing from the decal. It was then easy to mount them on the clean window. They look like subtle, sparkly, sweet outlines--non interference with the view. Now we'll see if they prevent the birds from knocking themselves out at my window.
