Not impressed

The black plastic ring got stuck on one of the plastic jars on third or fourth time of use. Now it doesn't work as designed. The screens seems to be of good quality and all are labeled for easy use(only reason for 3 stars)

Nice little classifier kit!

This is a very nice little classification kit. It’s a perfect size for putting into a backpack and going out for some sampling of areas. It’s by no way a “production” type classifier, but that’s not what it’s made for. It’s very well made and has probably every mesh screen you would need for sampling. It will process about 8 fluid ounces of material (about 3/4 of a regular size coffee cup) of material at a time. The clear plastic cups are nice to see the material as it’s being classified down, but will definitely scratch up and become harder to see through after use as mine has after a few uses. This isn’t a deal breaker as, again, it’s not for production and several shakes and spins is all it takes to classify the bit of material it takes.

Small like a peanut butter jar. Too much effort for so little this should have been larger. I understand the cost of SS for the screens but the price is astronomical for what you get. I doubt this will get much use as I have a system that works more material faster and the screw on style of the separator pc. Gets hung up on the fines.

A great system for classifying concentrates

It is a very nice small system for classifying your home concentrates. I changed out the jars with 14 oz. Jiff peanut butter jars so I could work more material at time. I only had to use 6 of the screens to get down to what I needed.
