Defender Spikes, Outdoor Wall Cat Spikes Bird Spikes Pigeon Spikes for Fences and Roof, Stainless Steel Bird Spike Defender Spikes Devices Outdoor Wall Cat Spikes Pigeon Spikes 10 Pack, Brown

I recommend this product ... easy to use, install and it is effective. If in the future, I need more ... I mostcertainly would purchase this item.

I don't like to be misled! There are not enough spikes in the box for the complete assembly of how this company states you should put the contraption together! Basically you will have to go to every other slot in order to have a spike when theoretically each spot should have two spikes! I don't like this. You ask for a certain amount of money for an item, but you short change the product. How would you feel if we didn't pay the required amount of money you were expecting. Don't waste your time on these, buy another brand that doesn't cheat. I am not even sure if they deter or not because I don't like getting swindled!
