I was sceptical about purchasing the flow mate, as I have literally tried everything else on the market, so I thought why not and purchased 2 of them.
This product is absolutely amazing; I can't believe it!!!
My neighbour's trees' constantly block up my gutters and I'm forever outside, in the rain unblocking them BUT not any more!!
I installed the flowmates, about 2 months ago and the water flows freely, even with debris in the gutter. I checked them last weekend, cleaned a small amount out, and put them back it-best thing I've ever bought!!
