WindowAlert Leaf Medley Anti-Collision Decal - UV-Reflective Window Decal to Protect Wild Birds from Glass Collisions - Made in the USA

Good: lovely design choices, really easy to use and effective, we've had no birds crash into our windows since these were up Bad: not much but if anything you have to get used to having something on your windows. They have a frosted transparent effect but you still see them. I did think they were a bit expensive as you don't get many stickers per pack but I've managed to use one pack on the middle pane of our window and it's worked really well Use: birds were crashing into my bedroom window more frequently so I found these and decided to try. They were instantly effective and I've bought another set for our kitchen window Buy again: Yes

Since fitting the decal to the conservatory doors, can say no birds have flown into them, result. Quick and simple to apply.

I've had so many birds, particularly larger birds, recently crashing into patio doors, these definitely helped. Certainly had no more crashes since. Easy to apply and stay put. Look quite attractive, certainly not distracting the view.

Was having a surge of bird collisions recently, with birds crashing into the windows on a daily basis (up to 7 in a single day!). Had taped some pieces of paper to the outside of the windows as a temporary mitigation, which worked but was pretty unsightly. Bought 6 packs of these about a month ago and replaced the paper on the windows with these, so far so good, no more bird collisions. Make sure you clean the window and stick these to the outside of the window to have it work best and last. Only down side is its a bit pricey - need at least 1 pack per window, so it can add up pretty quickly. But seems to be working so far, so considering it money well spent.

Absolute rubbish. I know baby starlings aren’t the brightest of the bunch but I had to remove these stickers as it was just non-stop birds banging into the window. Save your money and draw the curtains until they’ve worked out that it hurts to bang into the window!

Before we applied these we used to have birds crash into our bi-fold doors at least once a week, it was horrific! We’d come home and there would be a dead bird lying in front of the doors, or worse still we’d be sitting beside the door when the bird hit! These were really easy to apply and have been on the doors for a good few months now with no sign of peeling. We didn’t apply anywhere near as many as the instructions said were needed and they’ve still done the job. They look pretty natural, don’t obstruct your view and people have commented on how nice they look. A really good buy, don’t hesitate!

Look great and probably work well where you don't have a window cleaner using pole and brush. Ours came the day after i'd applied the stickers and they all came off, much to my disappointment. Found one sticker on the patio and washed it and stuck it to the patio door, but i know now that i need something else.

These window alerts are the best! Birds can't tell glass is there unless it has UV in it and it's so upsetting when they crash into our windows. We have been using these for years and if you position them correctly you get zero bird strikes. The leaf ones are very attractive. They are easy to apply to clean windows.

Easy to install, stick well. Don’t think you need that many for them to work, they are big enough. But they aren’t as “invisible” as I thought or hoped they be. But the designs are nice enough that it isn’t an eye sore. And the main thing…it seems to be working.

This literally saves birds lives. I just watched a bird change course because it saw one of the decals on my big window. It was headed straight for the window. Wow! Wow! Wow! Thank you for this great product!

I've used these decals for years. They are terrific. They have really helped keep birds from hitting our windows. They are easy to apply, they stand up to weather and they look good (not too obvious).
