Agreed yonny, the bad batch line isn't acceptable and wouldn't be acceptable in other retail areas!
Re kranks it is a shame as I've now lost confidence in a hook I really like. I don't get why any company would sell poor items and not have decent checks in place. Do they not value their reputation?
Two companies I now won't buy from are korda and tfgear. I'm sure a lot of their gear is good, but my disappointment with the kranks from korda and having got some bite alarms from Tf that were just toot, I will now not risk my money on any other products by those companies.
I'm reasonably confident Tf would have replaced the alarms, (they were ridiculously quiet and quickly died in the rain) but replacement is too late when I'm on the bank and stuff fails.
