Looking at the JBJ warrenty one sees this text
...JBJ aquarium products are warranted to the original purchaser against defective material and workmanship...
I order a JBJ item from an APC Sponsor, upon reciept I open the well packed box and see the glass is cracked. My first instinct is to contact the seller, thats natural, how ever the seller informs me that JBJ requires I deal directly with JBJ. This is obviously defective material. Due to JBJ's policy that is my only recourse.
or..
At lfs I purchase a JBJ item. As is MY routine I open the box to be sure all parts are there and notice the cracked glass. At this point I'd pack the item back up, take another from the shelf, check it for defects, and inform the lfs staff of the broken item. Since I have yet to purchase the item the onus is now on the lfs for the defective part.
However I really do think it is a bit much to ask vendors to open and test if possible all boxes before shipping.
JBJ futher states on their site
Upon discovery of a defect, the merchandise should be sent prepaid to:...
They are not hiding the fact that they handle these issues in house.
It's not the way I like business to be handled, it offends my sensibilities as both a consumer and an ex-business owner. You paid your money to me, I'll make it right. I also notice none of the mega-vendors, Big Al's, PetSolutions, Dr Foster & Smith carry JBJ regulators. Wonder why.
