Review on 🔧 Premium YOTOO Master Quick Disconnect Tool Kit - 22pcs for Fuel Line, Automotive A/C, and Transmission Oil Cooler Line by Jessie Ritchie

tools work. I've used them a few times but they don't look like aluminum. I think they're zinc - remember those cast cars from childhood? So far they've held up with little use I've given them. I wouldn't recommend them for a full time mechanic but if you need to disconnect some fuel lines a few times in your life I would recommend them for their reasonable price. Just don't expect them to last forever.
