Water was pooling behind my tub every single shower. I finally pressed one of these strips along the edge on a Saturday morning and the gap was gone in ten minutes flat.

Some gaps are just too big for a strip alone. My window frame had a quarter-inch gap that laughed at every tape I tried. Sometimes you need actual sealant, but still no caulk gun required.
Grab the squeeze tube version, no caulk gun needed. Just twist the cap and squeeze like toothpaste. Filled a gap along my window frame that strips kept falling off of. Dried clear and stayed put.
