I previously sent a email with regards to flush cutters I purchase
at Harbor Freight for $2. They are not all made the same. I used
one pair for months and thought it was the greatest thing. Just
recently I put the pair I was using at a students desk and opened a
new one. It didn't cut the same as the first one.
You’ve just discovered the most consistent thing about Harbor
If you think you’ll need more than 1 of an item from HF, it’s best to
buy them all at the same time. That way if the quality meets your
requirements they’re all apt to be from the same batch & quality.
Even then, it pays to inspect each unit carefully.
