I brought these Buzzygos to go with some I already had. I realised that I needed some on the front windows because I had prevented most flies coming in from the open patio doors, but I realised I needed to protect the front. I find they work well, they certainly keep out most flies at our house, we that's what my wife says.

It's an amazing product

Not sure how it works but have definitely seen less flies in my kitchen

I got these to try out on my campervan. Usually, on summer camping trips, flies get in the van if the door is left open, which is needed in warm weather. We camped in the oak woods with horse flies and small blue bottle types that live in woods buzzing 'round our heads on walks, annoying us. Only one horse fly got in. I stuck them to the metal part of the doors to start with, but the suckers lost grip a few times. Once I damped the suckers and put them on the glass window either side of the side door, they stayed on.

Maybe if the MK2 BuzzyGo had different ways to attach – magnets as well as a hook option – it'd give more choice of surfaces?

Haven't tried them in my house yet.

Very impressed with a huge decrease in flies entering the house
