Grainger warranties my Proto stuff without a problem. Blackhawk too.
It went like this everytime,
Counterguy "How can I help you?"
Toolhorder "I'd like to get this tool replaced under warranty"
Counterguy "Uhhh, I don't think we can do that"
Toolhorder "Why? It's lifetime warranty"
Counterguy "Does it have a defect?"
Toolhorder "Yeah it's broken"
Counterguy "I'll have to get the manager"
Toolhorder "Umm, Okay"
Counterguy "Please wait to the side sir"
Toolhorder "ok"
Manager comes in 10 mins. later
Manager "Hi, how can I help you"
Toolhorder "This tool is broken, I'd like to get it replaced"
Manager "uhhh, (insert tool brand here) isn't warrantied for life"
Toolhorder "Says right in the text it is when I bought it"
Manager "Do you have an account with us?"
Toolhorder "Nope, this is where they told me to go to get a replacement when I called on the phone"
Manager "you have to have an account"
Toolhorder "I feel like you're giving me the run around guy"
Manager "Company policy"
Toolhorder " Come on man this is ridiculous"
Manager "......."
Toolhorder "Should I call (insert tool brand here) right here on my cell phone so you can hear them tell me to come here?"
Manager "Not even sure we carry that tool"
Toolhorder "check please"
Manager "We have one but I'll have to look in this catalog for specific warranty coverage"
Toolhorder "OKAY"
Manager "It looks like it's lifetime warranty but what code do I use....."
Manager "hmmm"
Manager "um, here just take it and I'll figure it out later"
Manager "NEXT person in line!"
