Nice Cleco kit
Looks like nice stuff, havent used them yet

It's nice
Great little starter kit for classes taken in the aerospace industry. I've since added a 50 pack of -4 clecos, which is more than enough for the excercises that were assigned so far. My only gripe is that the pivot seems a little close to the end, making it just a little too short in grip and align the clecos and clamps before adding pressure. It's nothing that stopped me from using them, but compared to a larger and more expensive set of cleco pliers, you can see the differences.

Bad job made easier
My first time using a clecko. This is a really nice beginners set. Has all that you need for normal beginners metal work. I was replacing floorboards on 72 El Camino. Bad job made easier by this kit.

Sheet Metal Work On Cars? Airplanes? Anything?
The price, delivery and quality met all of my expectations! Any time you're fabricating with sheet metal and you need to maintain position of parts while you mark, drill, rivet or screw together, Clecoes make life so much easier. This was a great starter set assortment. I would recommend them to anyone--and when I need more, this will be my go-to supplier.

Why did I wait so long?
I bought these to help me hold a replacement floor pan to the unibody braces while I plug welded it to the brace. I wish I'd bought a set 20 years ago! I've been using them for all sorts of sheet metal mark-up and fabrication, starting at the center where things can't be clamped. This is a great starter set!

Beginner should be rephrased to 'starter set'
These are the same clecos you can buy in bulk and in use all over the aviation industry. perfect kit for the tool box, to use with small jobs, or as a start to a big collection.

PRO's — CONTRA's — Mein FAZIT …!!!
PRO's — + | + | + | + | + | + | + | Sehr gute Qualität, einwandfreie Verarbeitung, alles zusammen gut verstaut in den beiliegenden Säckchen …! CONTRA's — - | - | - | - | - | - | - | - | Leider steht auf den verschiedenen 'Pin's' nicht die jeweilige Größe/Durchmesser drauf, eine Unterscheidung oder Zugehörigkeit ist nur durch die unterschiedlich Farbigen Oberflächen möglich, leider …! Der, aus meiner Sicht, größte ⛔️ Minuspunkt zum Schluss: Trotz dass das 'Set' einen anständigen und auch gut verarbeiteten Eindruck macht, finde ich den Preis dafür doch etwas happig, also deutlich überzogen …! Bei dem Preis wäre es sicherlich möglich gewesen, die Größe/Durchmesser der jeweils verschiedenen 'Pin's' auf jeden aufzubringen oder einzupressen im Zuge der Produktion, sodass eine Unterscheidung nicht nur durch die jeweilige Farbe der Oberfläche möglich ist …! Mein FAZIT — + | - | + | - | + | - | + | - | Alles in allem ein gutes und zweckmäßiges Set bis auf den Preis, den finde ich persönlich wirklich etwas sehr tief in die Tasche des Kunden gegriffen …!!!
