The delivery of the sample was timely so I'm not knocking the vendor, however the product did not seem rugged enough for my needs. The product I received is 5.25" high (north-south direction) x 6" gutter run length (same direction as bead of black caulk on side that faces gutter trough, east-west direction).
Don't waste your time and money with other gutter filters! This stainless steel micro-mesh screen does everything you are looking for. It keeps out everything, including small needles and even asphalt shingle grit.

The foam type (which I tried first, starts degrading and crumbling after about a year. Plus, squirrels pull it out looking for seeds and small nuts.
