I have three teenage daughters, which means I am outnumbered 4-to-1 in a house of five, and I have learned that nothing in my home is safe from being borrowed. Chargers, sunglasses, my good Stanley tape measure. All of it ends up in a backpack and then in the void. So when I bought a $7 pack of silicone hair-tie-style bag clips and a $4 hardware-store carabiner set, I figured theyā€™d be gone by week two.

Itā€™s now week 11. I have questions, and a spreadsheet.

The Gauntlet

I gave the test three stations:

  • Backpacks: Clips hold the water bottle pouch closed and the lunch bag onto the shoulder strap. The Route 3 commute to school is a weekly stress test for anything not tied down.
  • Gym bags: Clips cinch the drawstring and the carabiners hang shoes off the handle. Gym bags get dropped, kicked, and shoved under bleachers.
  • The pool bag: This one hangs on the fence post by my pool. It sees sun, chlorine splash, and my water chemistry. I keep the pool at 7.4 pH and 3 ppm free chlorine like a municipal plant, so the bag gets a steady mist of the good stuff.

The $7 pack has 12 silicone clips at about $0.58 each. The $4 carabiner set is 12 small aluminum ones from Home Depot at about $0.33 each. Thatā€™s 24 pieces for $11, or $0.46 a piece.

The designer version was $18 for a set of 8 that I bought as the control: $2.25 a piece. Thatā€™s almost five times the price per unit.

The Spreadsheet

Yes, I built it. Columns for date, location, item type, and status (in service, lost, borrowed, or broken). I logged every Sunday night on the garage workbench with a 34-degree lager from the garage fridge.

The results after 11 weeks:

  • Cheap combo: 24 pieces, 2 lost. Attrition rate of 8.3%.
  • Designer set: 8 pieces, 4 lost. Attrition rate of 50%.

Cost per surviving piece: about $0.50 for the cheap stuff and $4.50 for the designer clips. That is a 9x gap.

My theory is that the designer clips are ā€˜precious,ā€™ so the girls treat them like accessories, borrow them, and lose them in friendsā€™ cars. The cheap ones are boring, so nobody bothers. Boring survives. Itā€™s the same reason nobody has ever stolen my pool test kit.

I did tear one silicone clip apart on the workbench to check it out. Itā€™s solid silicone, about 3 mm thick, with no hollow core, and it came back to full shape after I stretched it to about three times its length. The carabiners are zinc-plated aluminum with a spring gate that still snaps shut cleanly after 11 weeks of pool mist. No corrosion yet.

One of the two lost carabiners is, Iā€™m pretty sure, hanging from Neighbor Gregā€™s cooler. He borrowed it for a fishing trip. He also still owes me a 12-pack from the last time he borrowed my cornhole boards, so Iā€™m not holding my breath on either one.

The Catch and the Verdict

The carabiners are not climbing gear. They say ā€˜utility use onlyā€™ right on the package, which means wet towels and shoes, not a kid. Also, the silicone clips stretch a little on thick backpack straps, so Iā€™d skip them on anything heavier than a lunch bag.

Still, for $11 total, this combo handled three daughters, one fence post, and 11 weeks of sun and chlorine, and it lost only two pieces. The $18 version lost half of its set and still looks nice in a drawer.

Five out of five. If I lose a $0.46 clip, I shrug. If I lose a $2.25 clip, I start a spreadsheet. Oh wait, I already did.
