I need more time to truly review this product.
That said, here is what I can say.  The mounting is easy, the brackets hold up to heavy winds. There is nothing resting on  them, so nothing to clean.  The number of stars is low do to me not being able to test it. So far the product is fine, nothing broken or missing.  I do not notice any water issues on the ground. but I want to see it in action before I update the stars.  I can say that I'm not unhappy with anything so far<br />JUN 14th Update:<br />Had a good down pour the other night.  I had put down about an inches of mulch a few days before. I saw no movement in the mulch or earth. So I'm uping the stars to 5 since since these gutterless gutters are still clear.  Though I did find one issue.  You can not lean a ladder on them.  There is an easy work around. put the ladder up to the underside of them, then simple remove them. Then raise the ladder to the fascia. The ladder will fit between the mounts, so you can leave them installed, when adding solar panels as I did. I hope this is helpful.
