I used this coffee grinder just once for the sake of this review. I actually purchased it to be used exclusively for spices in the kitchen, mostly pepper, and It may replace my bowl and pestle for some other dry spices. I have become weary of using my hand-held grinder to grind one or more tablespoons of pepper when cooking. And I am supposing that I would not prefer to have pepper fragments in my coffee, nor coffee fragments in my pepper and other spices. And if the grind from this Secura happens to be inconsistent, it won't matter much for spices. So, I purchased this second grinder.The Secura is REALLY fast, albeit considerably noisier than my Capresso 560Infinity ($98.98). Is faster a good thing, or is it a problem? Some say faster affects coffee's taste negatively, but I ran each sample in the picture through my French Press, and I was really unable to detect ANY difference in flavor. But I readily admit, that's the opinion of just ONE person.I really like being able to simply tap the on-off button when it's finished grinding. Setting the grind size is really simple, using the dial on the left side. I made a mental note of the fact that turning either the grind size on the left to minimum OR neglecting to set the cup size won't allow the machine to be turned on. And as far as mess is concerned, I think the ejection port in the back of the ground-coffee hopper, coupled with a lid on the hopper does a good job of reducing the "overspray" to a minimum.The coffee I brewed from the Secura in my French Press MIGHT have had just a TINY BIT more sediment left in the bottom of the cup, but not enough to matter to me. Anyway, a bit more sediment seems to be intrinsic to wire mesh filters of any kind. I brewed both samples at a 16 to 1 ratio. Each tasted really good to me and virtually identical.The cup estimator dial on the front seems silly to me BUT IT DOESN'T HURT ANYTHING. I guess some people might use the cup estimator on the front to grind their beans, but I do not know how that could be useful. Even if it is at all accurate and consistent, what coffee to water ratio do you personally prefer and for which type of brewing? It doesn't make sense. And if you do not care about precision in your brewing, why are you buying a home grinder anyway? Use your kitchen scale to weigh your beans; keep the cup dial cranked all the way up, and grind your beans all at once each time you brew. Stand there for the few seconds it takes for grinding and tap the off button when grinding is finished.Any complaints about messiness are unfounded from what I can see. Yes, there are a few specs that end up on the counter, but a minimal amount IMO. Anyway, wild grounds, driven by static electricity seems to be pretty consistently a part of the home-grinding adventure! Put a towel under it if you like. Or it DOES help if you stir 1 to 3 drops of water in with your beans before grinding. (NO MORE than that!) Or I suppose you can do your grinding outside, but it's not worth it to me.Will it last? IDUNO! Considering the price and just in case, at 71 years old, I spent money on my first-ever product warranty. $7.00 gives me 4 years. I purchased the extended warranty because I guessed I might not use it enough to adequately test it during the factory warranty period. It may very well have been $7.00 of foolishly wasted money, but it's not a biggie either way. I grind coffee daily, but for spices this won't see nearly that kind of use. After 4 years, for forty-two bucks and if I am still vertical, I won't complain.
