Check the kitchen forum for some comments. I checked the website and it seems like a good deal, but most things are only available in chrome or stainless, if that is a consideration for you.

I have the Kraus also (just a few months old), but had the same exact wiggle. The install instructions say nothing about tightening this set screw, but when I called Kraus, the very helpful guy there said they send them from the factory a little loose so as not to get damaged. We already had the faucet installed and had to loosen everything so we could pivot the faucet base around to find the set screw. My kit also had two Allen wrenches, but neither one fit the set screw. So we had to buy a 3 mm to tighten it up. It's quite a simple process, I just wish they told you to do that when you are assembling the faucet. No yellowing of the hose yet, but it's only been a few months and my window faces east without a lot of strong light.

We have the Kraus KPF-1602 faucet. It's really nice. It came beautifully packed, and feels very heavy. Solid brass construction. Great water pressure. The finish is triple-plated like the very best brands. We bought ours from expressdecor because they were offering free shipping, and 10% off at the time (I just looked, and now they are offering 5% off, but 5% is still better than nothing). We've had the faucet in place for about 8 months, and it has performed flawlessly. This particular faucet is very tall, and would not work for a sink that has cabinets above it, but I know there have been people on this forum who bought other Kraus faucets and liked them. We were inspired by Robinst's photos of the same faucet in her kitchen. I'll link a post below where she and a couple of others talk about the faucet. I know Kngwd and Funfarm also bought Kraus faucets, so perhaps they'll chime in. Or you can do a search for threads by them and see if there are any updates from them. Here is a link that might be useful: Thread about Kraus KPF-1602 Faucet

Mine's 2.5yrs old and no leaks. We did have a stuck ON nozzle when we use the sprayer and they sent us a replacement. definitely contact them.
