Ideal Pet Products makes pet doors. I had one of their sliding glass door inserts years ago, and then used the cut-in doors at my last couple places, and Xta and I recently bought another door insert for the Sky Den. The cats promptly managed to break part of the door; I'm not sure if it was a manufacturing flaw in that particular unit, or if they were being particularly rambunctious, but they'd never managed to do that before. In any case, I was able to email Ideal, and they promptly offered to send a replacement part. Fixing it was as easy as undoing a few screws, putting in the new part, and screwing it back together.
Zyliss makes a variety of kitchen products, including rotary cheese graters. I bought this product because it has a wider barrel, which is good for coarsely grating medium-firm cheeses like cheddar and gruyere, which don't do so well in the narrow-barrel grater I use for hard cheeses. A couple days ago the handle on the coarse drum shattered. Although Amazon said their returns policy only covers things for 30 days, when I contacted Zyliss USA, they offered to send a replacement coarse drum, free of charge. So, yay.
I have to admit, I wouldn't actually buy this particular product again if I had it to do over; I like the larger drum, but the handle design is a little awkward, and you can tell it's a bit flimsy when you handle it. The problem is that it attaches at the rim, rather than having the drum closed on one side, or having struts across it, to allow the handle to attach at the center. Their smaller grater has the handle screw into a thread at the center, which works really well (and makes the disassembled pieces easier to clean). Still, given that I sank some money into it, I appreciate that Zyliss is willing to make some effort to maintain/service their product. If it breaks again, though, I'll probably just buy something else.
