When I first got the coffee grinder, I read instructions & decided to make sure I could take it apart for cleaning & reassemble. At first, could not get it apart, tried several times. I was about to call customer support but tried it one more time & this time it came apart easily, I was able to wash the hopper & lid, & reassemble burrs & put hopper & lid back on. So I’m guessing parts are a bit stiff at first. But after that works like a charm & I am able to t add me apart, clean & reassemble between each bag of beans. Nice size, doesn’t take over the counter, not overly noisy & once I figured out me perfect grind four my pour- over is a 7 (one step finer than absolute middle) grind) it is making fabulous coffee. 10/10 recommend.
