This device will make you want to settle down, raise a few little baby j’s, and move out to the suburbs to grow old together. Why? Because the GR8TR V2 is a grinder for life, in sickness and in health, 'til death do you part.

Self-described as “the world’s most advanced grinders”, and with good reason - the GR8TR V2 takes grinding your herb to previously unattainable levels.


The GR8TR V2 isn’t just your run-of-the-mill device - it’s so, so much more than that. Made of highly durable anodized food-grade aluminum, the attention to detail in this device is second to none.

With this grinder, Kannastor took a much more thoughtful approach to not just the size of your grind, but they also look at how to maximise the quality and consistency.

Made up of eight distinct pieces, you can also use the bottom lid as a storage chamber. This smooth-surface, contoured storage compartment is perfect for storing your keef, with a plastic scraping tool for easy collection.

Keeping your keef in mind, the GR8TR V2 set also includes easily interchangeable mesh steel screens, depending on your personal preference.

This herbal grinder also includes interchangeable plates to really tailor the consistency of your grind to your liking. You can even store one of these extra plates in the lid of your grinder - this is IKEA-standard storage efficiency.

The GR8TR V2 measures in at about two inches in diameter, and almost twice as tall at 3.5 inches high. Safe to say, this a hefty grinder with a lot of weight.

The size of the GR8TR allows for a much deeper grinding chamber that uses much less force when grinding, so rather than crushing up your dry herb it is lightly milled into smaller, fluffier particles.

Its large size and various storage compartments also allows it to hold a larger amount of herb, and the GR8TR can comfortable hold larger buds and up to an eighth of herb.

If you want to make the device a bit more portable, you can remove the pollen clear chamber altogether to make it more compact.

All of this excellence aside, the GR8TR is a pricier option than most grinders. Coming in at around £65, the GR8TR is an investment piece - and it may not be for everyone.

Sure, you can pick up any old cheap grinder, and no doubt it will do a fine job. But if you’re a regular smoker and you really want to bump up the quality of your herb to the next level, investing in a high-quality device and excellent craftsmanship will stand to you later on.
