If you’re complaining about price, you’re missing the point. There are many cheaper options if functionality is all you’re looking for, but premium materials and premium build quality comes at a cost.
Is it worth it? To me, yes. This isn’t a phone that you might benefit from upgrading after three or four years. This is a charger. It’ll last at least a decade, probably longer. For that amount of time I’m willing to pay 50% more for quality. And the quality of these things is very good.
As to the form-factor? That’s personal preference. I still prefer flat chargers like this, but Nomad do make an upright charger that’d work with the new standby mode, if that’s important to you.
