10 Pack Reflective Bird Repellent Windmill,Pinwheel Birds Deterrent Hanging Device Sparkly Silver Spinners to Keep Birds Away From Your House,Window,Garden,Farm

Very efficient. extremely difficult to assemble without any instructions but eventually found a customer's review, showing pics how to build. Once mastered then easy to build the remainder.

hopeless. no instructions, the video is no help and there seems to be missing bits in each pack. The videos show parts being used that I haven't received in any of my packs!Buyer beware - not worth it.

The media could not be loaded. Good quality but a bit fiddly to figure out from the poor instruction pic and video on the product description and doesn’t come with any instructions included. So I have included a slower video here which is hopefully more clearer for everyone. Once made they’re pretty sturdy and quite a bit bigger than I thought they would be.

Good quality and prompt delivery - no instructions at all at how to put together. Good job we knew what to do!!!!!

These bird scarers are really brilliant. We were terrorised by pidgins, their droppings all over my Hosta leaves and on the obelisks. However just 3 windmills have done the trick. They really are a very good pigeon deterrent.

We are struggling to put windmills together ??!! Didn’t realise they didn’t come assembled.

Works well seem robust as we’ve had some very strong winds and still completely fine

I bought ten of these, took an hour assembling them (they don't come fully assembled) and put them round my garden to deter pigeons, jackdaws and sparrows. The next day the birds were all back as usual.They should be marketed as a toy for kids, as they blow round in the wind and are bright and cheap.Otherwise they are garbage.
