How to choose a herb grinder that lasts

By the idoobi team · Updated October 2026 · All guides

Most grinders are not thrown away because they broke in half. They are thrown away because they became too annoying to use. Knowing how grinders usually fail tells you what to check before you buy.

What usually ends a grinder

• It clogs and sticks. This is the most common ending for toothed grinders. See why grinders get stuck.
• The threads wear. A lid that has been forced open a few times stops closing properly.
• Teeth wear down or snap. Plastic teeth are the usual culprits.
• The battery fades. In electric grinders, a battery that is stored empty for months loses capacity.
• Water gets in. Rinsing a grinder that has a motor can finish it in one go.

What to check before you buy

The grinding part

Metal outlasts plastic for the part that does the work. Ask what the teeth, blade or chain is made of. (The idoobi is bladeless and uses a stainless steel ball chain, so there is nothing to clog and nothing to clean.)

Replaceable parts

The part that wears should be sold separately and be easy to fit. A spare in the box is a good sign.

How it copes with residue

A design with nowhere for residue to pack in avoids the most common failure altogether. Our guide to chain, blade and teeth grinders compares them.

Battery care

For any rechargeable grinder: keep it dry, at room temperature, and if you are not using it, top it up for half an hour or so every couple of months.

Warranty and returns

The length of the warranty tells you how long the maker expects the product to work. A return window that still applies after use tells you they expect you to like it.

Looking after the one you have

• Keep it dry.
• Do not overfill it.
• Do not force a stuck lid with tools.
• Clean a toothed grinder before it gets stiff. Our cleaning guide has the steps.

How the idoobi handles this

How the idoobi is built to last

• The grinding part is a stainless steel chain, and a spare is in every box.
• There are no teeth to clog and no threaded lid to wear or stick.
• In about a year of daily use, our chain has never broken.
• It has a 1-year warranty, and the optional 5-year upgrade sends one replacement if it stops working for any reason, even an accident.
• It is not waterproof, so wipe it and do not rinse it.
