Cambio a este tras el fiasco con el wera y la nula respuesta por parte de ellos. Espero que la calidad de construcción interna esté a la altura de la marca. Por el momento buena pinta, un poco más gordete que el wera pero parece que internamente esté mejor construido que el alemán (era todo plástico y partió al año con uso profesional). Si hay novedades, actualizaré. Por el momento, buena pinta

I used to walk up to a rooftop unit looking like a pack mule, weighed down by a pouch full of nut drivers, six different screwdrivers, and a pocketful of loose bits that would inevitably fall into the condenser fan. I was a chaotic mess of steel and frustration. Then I bought the Klein Tools 32304 14-in-1 Adjustable Screwdriver. 1. The "Transformer" Technology: This isn't a screwdriver; it is a shapeshifting weapon of mass construction. The adjustable length blade doesn't just "slide"—it glides into position with the satisfying mechanical precision of a sniper rifle bolt. Need to reach a contactor buried deep in a cabinet? Click. Extended. Need to get into a tight control board space? Click. Retracted. It adapts to the job faster than I can complain about the heat. 2. The Impact-Rated Sorcery: This is the feature that made me weep openly on a job site. You can pull the blade out and stick it directly into your impact driver. Do you understand what this means? I am no longer switching tools. I am no longer walking back to the truck. I go from manual finesse to high-torque power in 0.5 seconds. It handles the torque like a champion. It doesn't strip; it dominates. 3. The HVAC "God Mode" Loadout: Klein didn't just throw random bits in here; they curated this for us. The Schrader valve bit? The Core Removal bit? The 1/4" and 5/16" flip socket that switches between shallow driving and deep bit-holding? It’s like the engineers read my mind and solved every annoyance I’ve had for the last 15 years. The rare-earth magnet is so strong I’m pretty sure it could pull a screw out of another dimension. 4. The Flip Socket: The flip mechanism on the nut driver is smoother than butter. Flipping from 1/4" to 5/16" used to require digging for a separate tool. Now? It’s a flick of the wrist. I feel like a gunslinger every time I switch sizes. Pros: Impact Ready: The ability to toss the shaft into my drill changes the game entirely. The "Core" Savior: Having a core removal tool built-in means I never have to hunt for that tiny tool I always lose. Magnetic Grip: Holds screws so tight you could practically hang off them. Bit Storage: The handle holds everything securely without rattling like a baby toy. Adjustable Reach: Deep cabinets are no longer my enemy. Cons: Theft Magnet: I have to watch my apprentices like a hawk. I saw a coworker eyeing this thing like it was a gold bar. I now have to sleep with it under my pillow. Too Efficient: I finished my service calls so fast that dispatch added two more stops to my route. Thanks a lot, Klein. Superiority Complex: It makes the rest of the tools in my bag look pathetic and inadequate. I can hear my old 11-in-1 crying in the corner. If you work in HVAC and you don't own this, you are working harder, not smarter. Buy this immediately.
