Great video! Exactly what I needed. The first one you showed was the one I need to attach a gutter directly to a cinder block wall without the gap a clip type would make. I think I'll install with Tapcons, and be prepared to replace with insert anchors if the Tapcons pull out.
Speed hangers also get in the way of leaf cover. And the upward angle of screw means is hard to get with drill when long shingle overhang is in the way.
doesn't using the clips over the back edge of the gutter move the gutter away from the fascia so water can get betwen the fascia and gutter? what do you use if you have a drip edge on the roof?
