Very good with long spikes! If you place them correctly, they do the job. I give 4 stars because they did not include double-sided adhesive tape as stated.

Discreet and quite effective bird repellents, but also relatively easy to install.

If the pigeons are determined, they don't help very much. Where I put them, they had already laid eggs, so it was impossible for them not to come back.

I bought the spikes for the garden because cats keep coming and fill the whole area with filth and it smells... together with gravel so they have weight. The cats haven't stepped there again.

Unfortunately, pigeons sit on top, It's not the fault of these particular spikes, another way to deal with them is needed

Very easy to install with double-sided tape, and effective. Since I put them up, I haven't seen pigeons or droppings on my balcony again.
Unfortunately, though, after a while, they learned to pass over them and stroll on my balcony.

I put these spikes on the outdoor unit of my air conditioner and on my balcony railings because pigeons used to sit on both the air conditioner and the railings from time to time. I think I have now gotten rid of the birds. Not a single pigeon has approached my balcony since I installed them yesterday

Tired of cleaning 'pigeon poo' off my air-con every other day. You can easily snap them to fit size / measurements..

Begone o' winged rat !

I was saved. It does the job, repels birds, and is not unsightly because it is transparent. I put it on top of the external unit of the Air Conditioner. I also attached it with double-sided tape, but it also has screw holes.

As soon as I put them on, the pigeons never landed again. They are also very convenient to put on and adjust as you like

Effective. The pigeons disappeared the first day I put them on, got annoyed, and never appeared again.

Very bad choice. Instead of repelling the birds, it helped them create a better nest. I threw them away and bought plastic netting and I relaxed.

They stuck with double-sided tape, they are transparent and have cutouts for proper application in case you need to cut them. I was very satisfied, from the first day we put them on, we were relieved from the pigeons!

They saved me!!!
Very good economical solution.
It can even be secured with simple adhesive tape.
We placed them above the external unit of the air conditioner and birds never approached again.

Hello! I chose this particular product because it appears to be transparent plastic in the photo, and I thought it would be discreet. However, I received white plastic ones that are more noticeable than the usual metallic ones. The order had already been delayed, and my balcony has turned into a mess, so I didn't have the energy for returns. Now, is it the fault of the store I chose? Maybe. I actually need more to cover the entire balcony, but I'm hesitant to reorder if I'll just receive whatever again. Just wanted to let you know if you were thinking the same way as me. If they do the job, I haven't had a chance to evaluate them yet.

It doesn't rust, you can cut it with your hand as much as you want, very effective, and more discreet for apartment buildings than the metallic ones.

It is flat on the bottom so you can also put double-sided tape, silicone, etc. depending on where it will be placed..., the plastic breaks easily by hand so you can cut the desired piece. It could also have holes on the bottom surface to make it easier to screw if needed. It was installed on an external a/c unit and the little birdie did not come! 4 stars only so that the price doesn't go up, otherwise it's perfect!

The only solution for pigeons after everything I have tried... and I have tried everything!!
In the past year, my house has become a pigeon house with the terracotta roof full of pigeon droppings that fall on the balconies, which constantly need cleaning.
Find a willing handyman to screw the plastic spikes onto a flexible aluminum rod and place it wherever you have a problem.

I placed it above the external a/c unit that had become a pigeon's nest and they disappeared.
Easy installation with double-sided tape.
I recommend it.

I have a problem with pigeons and other birds. This is the first time I am buying this product. I bought 10 and placed 4 in the air conditioner and the rest on the windows. I hope the problem will be greatly reduced.

The only pigeon repellent that delivers results! I ordered 10 pieces but my balcony is very large, encompassing the entire floor perimeter, so I might need to order another 10 or even 20 pieces for better results!

Really perfect product. As soon as I placed it, the pigeons stopped sitting. It's worth its money.
