Tribest GS-P502 Greenstar Pro Juicer Review

Delicious juices in bottles and fruits on table

What makes a juicer truly reliable? What’s the difference between a residential juicer and a commercial juicer? The differences are many, starting with the price and ending with the fact that commercial juicers can take a lot of punishment without breaking down.

Just because you want to buy a commercial juicer doesn’t mean that it will be loaded with features and accessories. But, that also doesn’t take away from its reliability in the long run, which is the main engineering goal. Here’s a perfect example of this.

Tribest GS-P502 Greenstar Pro Juicer

 In many ways, the Tribest GS-P502 Greenstar Pro Juicer is a beefed-up version of the GS-5000 Greenstar Elite. It’s perhaps less adjustable or versatile in terms of miscellaneous food processor functions. Nevertheless, this juicer sets the standard for reliability and consistency.

Who Is This Product For?

If you want to make massive amounts of fresh juices on a daily basis, there are few juicers on the market that can accommodate you as well as the GS-P502. This juicer is designed for commercial use. If you’re looking for long-term consistency, you’re looking in the right place.

It’s a masticating juicer that caters to anyone looking to make large batches of juice up to two days in advance. And, if you want maximum nutrient retention from any juicing ingredients, the reliable cold press process of the GS-P502 is addressed to you.

What’s Included?

Here are the components included in the package:

  • Masticating juicer
  • Plastic drip tray
  • Food plunger
  • Stainless steel strainer
  • Cleaning brush
  • Manual

Overview of Features

Although this juicer is slow, the power is used in masticating motion instead of spinning, so don’t worry about the 110 RPM speed. The specs of this machine won’t make anyone feel inadequate for real. (See? The propulsion of a space rocket doesn’t spin as fast as a car engine, but nobody is going to mistake the rocket for having less power.)

Besides juicing, the Tribest GS-P502 can also help you with making creams, butter, and frozen desserts. You just have to have the accessories, sort of like owning a food processor.

But even with a clean nonoxidizing cold press extraction method, there are still many things that can go wrong under full load and heavy usage.

You can prevent clogs or fix a jammed tube by using the reverse function. This applies pressure in the opposite direction. By changing the flow of the ingredients, it’s relatively easy to shake them loose and continue juicing without having to take the unit apart to clean it.

Overall, this is a consistent and low-maintenance commercial juicer. And the low-maintenance aspect comes from the fact that there are few moving components in the design. Therefore, there’s less stuff to twist, remove, and wash after the extraction is done.

The warranty is an interesting topic. For commercial use, you only get a 3-year warranty. But, if you want this as a residential juicer, you will be able to enjoy a 15-year warranty, which is about as long as you will find.

How to Use

The first thing to know is that some prep work is required. Although designed for commercial use, the GS-P502 has a rather small feeding chute; get ready to do some chopping before juicing.

Other than turning the juicer on and letting it do its job, there’s not a lot to worry about. Like any juicer, it needs the occasional thorough cleaning and of course, a good rinse after every use.

For this, you can simply take apart the appliance piece by piece and put everything but the base with the motor in your dishwasher. You can also use the cleaning brush and the scraper on any of the smaller components or the juicing screen.


Seeing as the Tribest GS-P502 is a commercial multi-function masticating juicer, it’s no surprise that it has a hefty price tag. For anyone looking for a strictly residential option, here are some interesting alternatives.

The Tribest GSE-5000 is cheaper and more versatile in terms of functions. While this is a masticating juicer, it’s not a commercial-grade juicer by any means. However, it’s still more than capable of juicing in large batches as long as you allow it some cool-off time.

Another option worth considering is the Breville 800JEXL Juice Fountain Elite. This is a centrifugal juicer that is also for residential use. You can’t use it for too long continuously as the motor needs some rest in between uses.

However, the speed of this centrifugal 800JEXL is mind-blowing for the money. If you’re only interested in an appliance for home use, the Breville might be a better fit.

So, what are you waiting for? If you want to change things up in your bar, then the Tribest GS-P502 should be a trusty appliance for years to come. It’s designed to handle continuous use and blow off the type of wear-and-tear damage that other masticating juicers might run into.

However, if you want something low-key but equally strong for use at home, the Tribest GSE-5000 might be a more appealing choice.
