Really Good Idea - Needs Different material
These strap locks are so simple, a great idea - BUT one caveat, the material they are made of easily becomes brittle and cracks or splits. I have used about a dozen of them, and they have all split in about 1-2 years. A better solution, like these, is the old "Grolsch" beer bottle rubber ring. Or, just get some of those seals/rings in bulk = about $12 for 100. They're much more pliable, and last a Long time! I love Fender, love these locks - but can not highly recommend them because of their failure rate - purely because of cracking/splitting. A softer, more rubbery, material may be the answer.
ProsWork great - do the job well.
ConsWill only last 1-2 years tops - they then crack or split.
