fantastic invention and tool. i have been lookign for a screwdriver with all of these features so i can eliminate 5 or 6 tools from my heavy bag. nothing worse than having to carry around a heavy tool bag all day. last but not least i still got my all in one screw driver though! last but not least the 3/8’s is also a big winner 🙂

If you do HVAC work this multi tool is great to have. Great for AHU, condenser, rooftop unit and furnace control panels that are secured with 1/4 or 5/16 bolts. I like the thermostat flathead screwdriver bit, not to mention the schrader core remover. Would definitely recommend!

Phillips & flathead bit comes out too easily. Flathead bit twisted within 1st day & is not very strong. Phillips bit could be fatter. The bits are just too soft. I went back to carrying two individual screwdriver that are stronger for tightening

I had a few problems the first time I used it.1st the slotted and Philip bit kept fallen off. 2nd the small 1/8” slotted snapped to easy. I have always been into Klein tools and was excited for a tool just for HVAC made by Klein.

Must have if you are an HVAC professional! Great tool for an apprentice to grab to do lots of different job tasks when starting out. My favorite part it the 5/16” and 1/4” but drivers that will save you in a pinch if your drill dies.
