Bottom Line

The SLX is easily the best manual grinder around, its unique trapezoidal teeth and non-stick ceramic surface deliver the finest, fluffiest ground herb at a consistent level. It does so with minimal effort from the user because the teeth chew up the herb quickly and efficiently. The magnetic lid with indentations cut into it for a better grip just makes the SLX even more convenient. It’s clear, if you use a dry herb vaporizer, then you need to use the SLX with it.

SLX Grinder Review

SLX Grinder Background

SLX Grinder Review

The SLX is a four piece grinder that includes a pollen filter (upper right) and a scraping tool (middle).

If you’ve been vaping dry herb for any length of time, then you know how important a great grinder is to a great vaping experience. The reason is that weed vapes work best when the herb is as fine as it can be because that increases its surface area, which allows it to be heated up more evenly. This maximizes the vapor and flavor production of the herb, and also increases its efficiency because you can do more with less.

There are manual and electric grinders to choose from, they both have their pros and cons, but if it’s a manual grinder that you want, then you can’t really do any better than the SLX. It’s easy to use, has all the features you could ever want in a manual grinder, produces extremely fine herb, and never needs cleaning. Yes, I’m serious. If you’re still reading my SLX grinder review and haven’t gone to buy one yet, then what are you waiting for? More details? Well, keep reading then.

How it’s Designed

SLX Grinder design

The SLX uses trapezoidal shaped teeth to deliver a fine grind with minimal friction.

The SLX looks like any other manual grinder at first glance, but look a little closer and you’ll see what makes it stand out. First of all, there are flat indents cut into the edge of the lid that makes it easier to grip while you’re grinding. The whole thing is made from tough, yet light, 7075-T6 aluminum that is tougher than the aluminum used in the construction of other grinders. The lid is attached to the rest of the grinder by a powerful magnet instead of being screwed on by threads. This makes the lid much faster and easier to remove than threaded lids, while still remaining secure.

Now for a trip inside the grinder, it has fifty five sharp trapezoidal teeth that are the secret to why it creates such a fine grind. They are far more efficient than the diamond shaped teeth in most other manual grinders. The inside has a low friction, non-stick ceramic coating, this is great for a number of different reasons, well two. The low friction nature of the coating gives it a smooth grind every time, so you don’t need to have Popeye sized forearms to grind down the herb.

The other, even better, reason is that the non-stick coating means that it never needs cleaning, since nothing ever gets stuck to it, not loose herb, not resin, nothing. I’ve had mine for years without cleaning it and it’s practically as good as new. There is one downside to the SLX though, and that is that the bottom section beneath the kief catcher screen—i.e. the screen that filters the pollen from the bud—is not magnetically attached, so you have to hold it when removing it from the rest of the grinder. It’s annoying at first, until you get used to it.

How it Performs

SLX grinder performance

The SLX consistently delivers fine, fluffy ground herb no matter what strain of weed you use with it.

As you’ve probably figured out by now, the SLX performs like a champ. Every grind is smooth, regardless of the consistency of the herb, it always turns out nice and fluffy and perfect for vaping. The grinding action is nice and smooth and I’ve never had to apply excessive force to keep the SLX moving.

I’ve used the ground herb from the SLX with a number of different vapes, each of varying quality levels and price points. Naturally, the vaping experience differs based on the vaporizer, but in each case I was clearly getting the most flavor and vapor possible. One of the best things about the SLX is its consistency, you get the same results from your herb every time.

As I said earlier, there is no need to clean it after a grind because the non-stick coating does its job. You might have to blow away some remnants, but that’s all. The SLX is pretty durable too, I’ve dropped it a few times and it’s none the worse for wear, not to mention that it still works perfectly after the three years I’ve been using it.

The Last Word

The SLX is clearly the king of the manual herb grinders, there are a lot of good herb grinders but this is one of the best herb grinders. It does everything at a high level, even those people who prefer electric grinders might be tempted to switch after using the SLX. That is because it produces some of the finest, fluffiest herb of any type of grinder.

It does so quickly, easily, efficiently, and with less fuss than most electric grinders and pretty much every other manual grinder, it also grinds a lot more herb at once than most electric grinders. So, it’s clear, no matter what kind of dry herb vape you have, it will work best if used with the SLX, it’s your grinder’s best friend.

  1. I got this grinder after reading your reviews and it being your top pic of 2016. I really want to like this grinder; they *almost* nailed it perfectly, but there are just two things about it I struggle with:

    – The lack of threads on the screen-section unfortunately results in a TON of fines and keif getting everywhere inside the grinder as you grind, making it impossible to open OR close the grinder without making a mess everywhere each time
    – I’m not a fan of the larger holes towards the center of the grinder – I’m not sure why they chose to do this. I’ve noticed that as I’m breaking up my herb and placing it on the grinder, medium-sized pieces end up falling through these larger holes before I get a chance to grind them, resulting in a rather inconsistent grind at times.

    That said, I love everything else about it:

    – Excellent build quality/construction
    – Buttery-smooth grinding feels
    – Ceramic non-stick works as advertised. Also feels great to the touch!
    – I like that the magnet stems from the grinder and not the lid, so as to not accumulate sticky
    – Screen section does not have threads so it’s shorter than most
    – The plastic washers adds to the buttery-smooth grinding feels

  2. Overall I like and agree with your review.
    However this statement is not true -”During my sessions, I felt the difference between the SLX and lower quality grinders. Using the SLX produced dense vapor, with better quality, and extracted more out my herb.”
    The grinder has NO effect on vapor density, quality or extraction – that is purely down to the vaporizer used and NOT the grinder – don’t mislead people.

    • I mean using a good grinder makes a huge difference. Of course, there is no noticeable difference is you use the SLX or other quality grinders.
      If your weed is not ground properly, you will fill it during your session 100% doesn’t matter which vape you use.

  3. Hey,

    i imagine the herb is best for vaping, what can you do with the pollen?
    and, can i use the grinder without the stainless steel screen?

    thanks for the great review

  4. Well just got this one a few weeks ago and I love it, anti stick works great, takes a while for any muck to build up and if it builds up it’s very easy to remove, if you brush it out regularly it just stays clean.
    It collects pollen like crazy but I feel with all their precision engineering they could have made the pollen screen fit snug instead of rattling inside.
    The grind is very ideal but I’d like to give it a few turns upside down and then grind and let it fall through.

    Together with the Pax3 and a bubbler this is actually the most efficient way yet, good grind, pollen bonus after a while and with the Pax & bubbler you get a clean hit and if you don’t vape too hot the residu that remains in the pax tube is actually a very nice clean oil that is also easy collectable. I’ve never before extracted so much from so little.
