I too fancied the Knock Hausgrind and spent several months watching their site, twitter and facebook pages without any luck. I even emailed them to express my interest...and got no reply.
My Lido 3 arrived today and a very nice piece of kit it is too. However, I was very disconcerted to find that the adjustment ring would only make half a turn (8 marks) rather than the 2½ it is supposed to turn through. A quick trip to the net and I discovered this isn't uncommon:
"I began to adjust the rings and noticed that my adjustment ring would only rotate a half rotation (zero mark to 8 notches), regardless of how loose the locking ring was - almost as if the threads were getting stuck." (

However, on that same page I read:
"I just got one and totally had the same problem with mine. It only moved from 0-8, the burrs were super smashed together. The good thing is I had waited so long I had watched Doug's realigning the burrs video a couple times waiting for the grinder. So I did nothing with the top screw, and followed his technique. It was much better after, but I had to push the handle/upper part up and down against the hopper, and then I could see the burrs adjusting up and down looking from below as I turned. Now after having put some beans through it things are smooth, the grind seems consistent and the zero is stable. I've had it now a week and it's been an eye opener for me in terms of what coffee can be."
The videos in question show the Lido 2 but apply equally to the Lido 3:
A few minutes with the tool provided...and it's now fine. I took off the safety washer and the adjustment ring before simply loosening the bottom four screws, whereupon the handle/shaft could be used to push the centre burr about 1 cm clear of the outer burr. This freed up the mechanism and allowed the shaft and bearings to be aligned as in the video. Tighten up carefully, reassemble the ring and I'm good to go.
Not shown in the video are two nylon rings/washers...one on the shaft at the bottom bearing and one under the adjustment ring. Don't loose them!
Not quite what I'd expect from a new bit of kit, but hopefully I'm now sorted for a good while and won't spend so long grinding away as with my Hario mini!
