Review: Great product - Excellent product got the job done
Review: Excellent! - I bought this set because I needed both tools to replace a water inlet valve inside my washing machine. I figured the parts and tools would be much cheaper than having a repairman come out to fix it for me. They worked perfectly and the magnetic feature was the best part! I was afraid of dropping things down into or under the washer and being unable to complete the repair on my own, but these tool were simply fantastic and held the tiny pieces securely until time to put them back after I replaced the valve. Now I have 2 excellent tools in my collection for my next home repair job! Couldn’t be happier!
