I wouldn't care for a NZ grinder as I'm not into single dosing and can't stand the design, especially the wood accents. Having said that, even the OEM burrs in a NZ are much more costly than $35. If anybody with any sense of judgment thinks something like this might be even remotely possible they need a reality check. This sort of what I call B.S. spam/scam advertising gets old. Awhile back I was looking at a device that's quite important and typical realistic price was in the $170-225 range and of course some dinky Chinese type ad pops us claiming to have the same thing for like $65. Of course estimated arrival was 4-6 weeks, a Google check of their site proved it's ridiculous in nature and far from trustworthy. How some in this world get away with scamming people is beyond me and gets old.
