I've bought these several times from the same seller, in different sizes. Good quality metal and rubber. Not flimsy at all. Lived under SUVs and horse trailers for years in mud, water, ozone, desert air, etc. No damage to aluminum or rubber. The 3/4" size is perfect for the 1/2" plastic cut loom. The 1/2" size is ideal for a Bundles of two or three 16 gauge wires. I was particularly impressed by the mounting hole. It's big enough to fit under a 1/4 inch screw. And the tongue is long enough to accommodate the screw head and washer. Cheaper quality clips sometimes won't fit something larger than a #8 self-tapping screw, and even then the tab will be so short that the screw head won't fit. You don't have this problem.
