Thought I'd stay out of this one, but with all the recriminations going back and forth, I thought I'd put my 2 cents in.
I've never dealt with Cell_man. He's not sold me a thing, helped me out or otherwise done anything to benefit me (aside from contribute his knowledge to the forum, obviously). In other words, I have absolutely no loyalty to him.
However, what this thread has shown me, is that Cell_man has gone above and beyond what is generally required of a internet seller, and I'm a pretty harsh rater on eBay.
In business, there's few things that have unconditional warranties. Even if you bought a brand new BMW, with a 5 year 'unlimited km' warranty, if your engine seizes, they will dump your logs, look for evidence of modifications and use any excuse to deny your claim. Often they will wait until consumer affairs to get involved. Likewise, most internet sellers do nothing about complaints until paypal gets involved, and the only successful claims I've heard of is where outright fraud is involved (item not sent, or item doa or certified imitation). The expectation these days is that ifthe user could have broken it, the user did break it and warranty doesn't apply.
It seems to me, that its not even clear that the plate was faulty. it could have been abused, used out of specification or anything. If it wasn't cracked on delivery, tough - more likely user error than defective item, and yet it seems like cell_man is going beyond obligation to fix it gratis.
If I were Cell_man, I wouldn't want this thread deleted. It might drive away 5% of customers, but attract 95% of customers, who have more realistic expectations. But here's the clincher - there are some customers who cost you more to service than you make from them. Those customers, you don't want anyway - and in my opinion, those are the ones that would avoid Cell_man now anyway.
