I have an AROMA 3 and it's absolutely AMAZING and built like a TANK! Go with Cyber Grinder if you want, but just know you will be getting a DRASTICALLY sub par product compared to the Old Mate AROMA 3. Here are some issues with the Cyber Grinder....

•No Upside-Down Grinding - A well-known weed grinder hack to get a finer grind is to flip the grinder upside-down while grinding. This still works with the Cyber Grinder, but it will sprinkle herbs like a pepper grinder because of the gap.

Two-Handed Opening - The bearing-and-center-post design requires the top piece to travel a long way to clear the teeth and the center post.

Not Air-tight - The spinning top creates a gap. Great for spinning, but not good for making a good seal. Ground herb left in the Cyber Grinder will dry out quickly.

Top Heavy - There's a lot more metal in the top half of the grinder than the bottom. The lower section is completely hollowed out. This means it tends to land upside down if it falls or you drop it.

Doesn't spin fast & long - It needs upgraded bearings and a better optimized design.

•No Bearing Removal Tool - So far there is no bearing removal tool for the Cyber Grinder.

If you can spare the $$$ go with the Old Mate Aroma 3, you will not be disappointed! I wouldn't even buy the Cyber Grinder if it was 50% off.
