Product review (2 stars): Frustrating and absurd.
I hate when things are built to fail and it seems like this spray arm is one of those things. That in itself isn't worth a bad review, because if you read through the reviews obviously people are satisfied with this thing, but it IS frustrating to fit. Heaven forbid they build it right the first time, but instead when you buy this "equivalent" (better) replacement part it will hardly fit. I was just about to return it because I thought i bought the wrong one, having the exact same problem as others trying to screw it on. I started trying some of the methods (before i read the reviews) but gave up thinking I had bought the wrong one as I said. Now that i know it will go on I'll either have to hold the piece down with metal (I tried with plastic and it didn't have enough resistance) or I'll have to take out the washer and hold it down from on top. Either way, while everything will probably work (I haven't done it yet but imagine I'll get it tomorrow) I think it deserves a bad review for the aforementioned reasons; Also when I have a part that won't fit or something confusing about a product I look for bad reviews so someone can explain it. Hope that explains why I am giving it a bad review and I hope you found this useful. If you need it buy it. But always take note of the companies that build poor quality appliances.
