Flair Power Tower Compatible with 1Zpresso - Electric coffee grinding tower for manual hand grinders

The Flair Power Tower is a great improvement from manual grinding, especially for espresso. It greatly improves my workflow, allowing me to free up my hands for other things during puck prep. It is much quieter compared to the Baratza Encore I was using before. I can still have conversations with others in near proximity while grinding coffee, but not so quiet that it wouldn't wake folks up in the morning.It works well with my 1ZPresso K-Ultra. Getting my grinder in the holster was mostly painless. It does require a good tightening of the nut to prevent the grinder from twirling in the holster. It comes with a silicone wrap to protect the grinder while sitting in the holster as well.The hopper is a bit kludgy. It sits on the outer lip of the grinder, so that when you pour your beans into the hopper, they tend to catch on the outer lip of the grinder instead of all sliding in nicely. It's probably the best they could do for a one-size-fits-many product. And, there maybe some easy after-market hacks you could use to make improvements on this.Also, adjusting the grind coarseness or fineness while in the holster is a bit of a tight squeeze. It would be nicer if it was a littler easier to make adjustments.Overall, I am very happy with my purchase and would buy again.
