Great find
Really solid set. The color-coding makes grabbing the right size fast, and the extra-long arms give you good reach when you need it. The ball-end feature is handy for working at angles, and the keys feel tough and durable. The compact caddy keeps everything organized.If you want a reliable hex key set thatâs easy to use and built to last, this oneâs a good pick.

High quality
I was sick of the small little unlabeled cheap Allen kits from big box stores so I splurged on these and havent regretted it for a second. These are SO much nicer, easier to identify the size, easier to use because of the length, super well made, and the storage solution of having them in the holder is amazing.

These things are bigger than I expected â¦in a good way
I know, Klein tools. I know theyâre always well-made, but these hex wrenches are actually longer than I expected. They are fantastic pleasantly surprised, and the color coding is really a great feature.

Impressive quality from klein.
A+ quality from klein on this one. These are definitely the nicest allens I’ve ever used. I was not expecting such quality, but they have very little flex, the case is nice, and the color coating makes things incredibly convenient when you fullly familiarize yourself with what is what. I would recommend this product to anybody if it’s within their budget. This isn’t your typical ‘klein tier’ tool. In the world of pliers, cutters, etc.. Klein is generally considered the acceptable tier option for pros. Whereas brands like Knipex, and even Icon from harbor freight outshine them as far as the upper end quality goes. Not these, these are very quality.

Well made Allen wrenches
Iâm a industrial maintenance technician and I go through a set of Allen wrenches about once a month they normally get rounded off or break I got these because I love and have had good luck with this brand of tools so far on week 2 they have no signs of wear the only dislike is the rubber cover on each Allen makes it hard to quickly pull each one out of the sheath but overall Iâm very happy with this product

Perfect for My Purposes
I recently got into 3D printing, and it turns out, I got a bit of a lemon of a machine. Because I have had to disassemble and reassemble the extruder quite a few times, itâs come to the point that the cheap Allen keys included with my printer are stripped and wonât work anymore.That was when I realized my husband had somehow never bought a sturdy set of Allen keys for our home toolset. I decided that even though I only needed a few smaller sizes, I wanted to get a decent sized, sturdyset for our toolbox, and when I saw the colors, I couldnât resist.Theyâre perfect, I love them so much. Theyâre much heavier duty than the tools I had been using, and definitely I feel like I got my moneyâs worth. My tasks (which came up again right away after the tools arrived!! Good timing) were much easier with these superior tools.The included holder is cool, but it is quite difficult to slide them in and out, so itâs not really useful for someone who is frequently pulling their tools in and out on the job. I just keep the two smallest sizes out with my 3D printing tools, and put the rest away in case a need ever arises in the future where we need a larger size.I have had some of the logo on the tools scrape off right away, but it was only the brand name, not the size, so it hasnât bothered me. Thankfully the color coding will keep them identifiable even if the lettering does all come off (I donât think it will, the brand logo seems slightly different).

Nice set, but flawed holder.
Nice looking set. I found that some of the keys are very hard to take out of their holder. I mean REALLY hard. I actually bent the 3mm key trying to take it out of the holder. The lettering that has the logo and size printed on the keys wears off quickly. I ended up 3d printing a new holder for the keys. I could have used a lesser set without the largest keys, I imagine this might have been cheaper and also much easier to store.

Herramienta para hacer reparaciones en el hogar. Son de muy buena calidad y muy duraderas. Hay otras marcas que se degradan al primer uso, estas ya pasaron la prueba. Tengo otras herramientas Klein y la calidad se nota en todas. Excelente marca.

Se ven y se sienten de calidad. Al menos el metal. El plástico se ve que se raya rápido. A pesar de que venÃan en su caja original me dio la impresión que se usaron al menos una vez. Ya que algunas vienen sucias
