If you need to grind the coffee to roughly the desired coarseness, it will do just fine. Plus, it's made of strong plastic, so if you treat it well, it will last a very long time (I've had mine for a few years now). If you are planning to get one for a lever coffee machine, only if you have pressure relief strainers, which will forgive you. But I sense three absolutely fundamental problems. First, the individual steps are set by tightening/loosening the "nut" at the bottom of the grinder. You can tell when the gear changes by a faint click. Sometimes so faint that you're not even sure if anything has really changed. And the whole setup is relative - you never know exactly what you're on, just that you've tightened one click, loosened two, and so on. So if you need to know exactly that you're at, say, stage 3, you'll have to tighten the grinder all the way down to zero every time (and even that doesn't really ensure a consistent setting, because even what looks like zero is usually a click tighter) and count off the stages you loosen. Or constantly remembering in your head how you've been resetting the grinder and doing mental math with what stage you're currently at. And even if you suffer through this, there's a second problem, which is that you may well find that for a given combination of coffee, batch, and basket, for example, stage 2 is so fine that it clogs the machine, but stage 3 is so coarse that the water runs through the portafilter too quickly. You also have to find the type of coffee that fits the grinder correctly. And even if you wrestle with all this, find that perfect grade, coffee and dose that extracts perfectly, the grinder has one more underbelly, a third problem, in reserve. He cannot reliably retain the coarseness of the grind. You grind three to five batches, and by the fifth, the machine is peeing in your cup instead of your espresso. And the whole setup fun can start all over again. For drip coffee, French press, cold brew, Turkish (in a jazzercise), or espresso with pressurized strainers, I think the grinder is perfectly solid - it has wide coverage, and for these methods, it doesn't matter too much if you miss by a degree here and there. But once you demand the fine precision and consistent, unchanging, repeatable coarseness that classic espresso needs, attempting home barista techniques with this grinder will be a punishment. And the anger that the third batch of coffee is going in the trash while you've been standing at the machine for fifteen minutes and still haven't got your desired caffeine supply is more energizing than any coffee, just not in the desired way.
