Our Reviews

Golden Bell 4 Piece Grinder

The Golden Bell 4-piece grinder is a standalone grinder with no extras included apart from a pollen scraper.

Perfect as a backup grinder and extremely well priced. The Golden Bell grinder is made from heavy-duty zinc alloy and comes with a magnetic screw-on lid.

Make no mistake, this is by no means a premium product. But it is more than an acceptable backup or beginner grinder.

At the $7 – $8 dollar range the build quality is adequate.

The catch chamber is a little small and doesn’t hold as much as some other grinders, but at this price, you can’t really complain.

The micron stainless steel mesh could also be better.

Overall, the Golden Bell 4-piece grinder offers smokers another viable budget option.


  • Great price
  • Lifetime warranty
  • Heavy duty Zinc Alloy design
  • Magnetized lid
  • Pollen scraper included


  • Catch tray is shallow
  • Thread easily damaged when screwing & unscrewing
  • Grinding action stiff

All come in a jet black design with the white Kozo logo emblazoned on the surface.

The tray is an ideal size for holding your ground up weed whilst rolling up.

The smell-proof UV jar is built extremely well and will release little to no odor. Which is always a bonus if discreteness is required.

The Kozo grinder is made up of a 4 piece aluminum design. Which incorporates a strong magnetic lid which keeps your bud secure and free from any spills or mishaps.

A sharp grinding teeth section is next, which grinds up weed exceptionally well.

The third section is a mesh filter that produces a mighty fine herb.

Tree of Life Stash Box

Next, we have another 4-piece kit by Swagstr Grinders.

The first noticeable thing that catches your eye with this grinder kit, will be the Tree of Life design.

This is emblazoned to the lid of the bamboo stash box. It’s a stand out feature and does exactly what it’s meant to do, stand out!

The box also comes with a lock and 2 keys, which is ideal for the more private cannabis users.

A padded inside compartment is another feature many users will appreciate.

The rolling tray is more than adequate and is of a jet black design with the Tree of Life and the Swag Gear logo printed on it.

iRainy 5 Piece Grinder

Cheap and dependable, this 5-piece budget grinder by iRainy is another great option for the cannabis user on a budget.

Again, it’s a standalone grinder rather than some of the kits we’ve previously reviewed.

But this is not always a bad thing. Not everyone needs a kit, and a basic grinder may be more than sufficient.

Consistently rated 4 stars and above, the iRainy 5-piece grinder is made from a durable Zinc Alloy material and is fully black in color.

For a 5-piece weed grinder, the iRainy grinder is both unbelievably lightweight and portable. Yet it is just as durable as many other grinders in its price bracket.

Weed Grinder Sizes

Weed grinders come in a variety of sizes, or to be more specific, pieces.

There is no best, or recommend size. What size weed grinder you buy really just comes down to personal preference, and should only be bought if it suits your requirements.

The most common sizes you’ll see are:

5-piece weed grinders can also be found, but are not commonly used or considered to be one of the more popular designs. But again, this is all personal preference.

If you need or prefer a 5-piece weed grinder, buy a 5-piece weed grinder. As long as the build quality and price meet your requirements, that’s all that matters.

Weed Grinder Build

Weed grinders are available in many different materials.

Again, cannabis smokers will have their preferred type, but unless they’re made from very cheap materials. Most will work as they should, no matter what they’re made from.

Some common materials weed grinders are made from, are:

  • Wood
  • Titanium
  • Steel
  • Aluminum
  • Zinc Alloy
  • Plastic

Different Parts of a Weed Grinder

The different parts of your weed grinder will directly relate to what size weed grinder you decided to purchase.

For instance, some budget 2-piece weed grinders will only have the lid, teeth/grinder section, and collection base.

Whereas, your 4-piece grinder may incorporate a mesh screen, or sometimes 2 mesh screens, and a section to hold your bud, as well as the above.

Many will also include extras, such as a pollen scraper.

If we presume it’s your 4-piece weed grinder with above average build quality. The below will normally come as standard:

  • Magnetic lid (helps to secure your product)
  • Molded or engraved grip
  • Grinding section with sharp well placed diamond shaped teeth
  • Mesh screen section, to collect/filter fine powders
  • Base section, that holds your weed crystals & pollen scraper

Before Deciding on the Best Weed Grinder

There are some important details to consider before making the decision on what weed grinder to buy.

Teeth: The amount of teeth, and more importantly the placement of teeth should be a top priority when considering what weed grinder to buy.

Cheap, badly made weed grinders are notorious for badly ripping and shredding weed.

Never mind the headache of having to pick the weed out of the teeth when it becomes stuck, it’s pretty tedious.

Sections & Rims: Some weed grinders have a problem of weed build up on the rims.

Which in turn can hinder if not completely stop the grinder from being turned.

This problem can also appear on the lid of the grinder, especially if it’s threaded.

Of course, regular cleaning will help. But you know you have a cheap, badly made grinder when you’re having to pry open the different sections.

Capacity: Storage capacity is another important factor to consider.

Your grinder may be the best grinder you’ve ever had in every other respect.

But if it can only hold a small amount at a time, this can become a real annoyance if you’re a regular user.

Ease of Use: Your weed grinder should be easy to use, without all of the above problems.

Essentially, it should be doing all the basics right and none of the bad.

If not an enjoyable experience, it should at least be an easy one.

If you need to constantly struggle or go that extra bit just to have nicely ground bud, then your weed grinder probably needs replacing.

Affordability: Price is another factor when considering what weed grinder to buy.

Is it a standalone weed grinder, or weed grinder kit?

Will it be a 2-piece weed grinder or a 4-piece?

What about the build quality!?

These are all important factors to consider, that inevitably increase the price of the product.

And like most things in life, the more premium products will always undoubtedly cost more.

But, that doesn’t always mean the most expensive is the best.

There are some fantastic weed grinders out there at budget friendly prices.

So look about, you may just find yourself a bargain!


There you have it! A comprehensive 5 product round-up review and guide on buying the best weed grinder.

Our top pick out of the 5, would have to be the Kozo Wood Stash Box Kit.

This 4-piece kit has everything you need, whilst being from a well known brand, highly rated and a quality build. All this, at an exceptionally good price.
