Yeah, they are a pain in the a** to review compared to some other things...hence "moth to a flame."
I tend to get them because people find some of my reviews of faucets helpful. Sometimes I get models that nobody really wants, though, so not many people look at the reviews. I don't take them apart to check out the internals. That would be potentially helpful to folks, but I honestly wouldn't know how to predict reliability or longevity based on what I'd find. Plastic sounds cheap, but sometimes it lasts longer than metal depending on the application.
I ended up with another faucet in part because Vine this past week was - brace yourself for a first-world problem
- an exercise in frustration because the website was locking up for a good 25 minutes. Keep in mind, good products tend to become unavailable in seconds, so it's not a particularly stress free activity. I'd pick a product, ask for it to be sent to me, then get the "we're experiencing problems" screen. Time and time and time again. Well, so was everyone else, so I can't say that I ended up any worse off than I would have been. Luckily there wasn't anything that I really wanted this time, so it wasn't too bad. I missed out on a memory card reader, which would have been nice because I've been wanting to get one. I snagged what I
thought was a radar gun and was super excited (because I've always wondered just how fast people are going on the street near me), but it turns out to be a radar scanner to find stuff in the wall (like studs, conduit, and wires). That would actually be very cool, too, but it has nine one-star reviews - out of nine total reviews. It's apparently an absolute piece of c**p. Oh, well. Gadgets are fun.
