Customer Reviews

Fantastic customer service Review by Ken Porter
I called in the afternoon on Friday of a holiday weekend. I had a few questions before purchasing. Trevor was outstanding! He answered all my questions and had my complete order shipped that day. I received my order on Tuesday the day after the holiday. I ordered the 40# unit with an extra small drum for small batches. All of the equipment is very well made and will last me a lifetime. As for customer service, it was to say the least outstanding. Trevor even stayed over after closing for the holiday to ship my order. I highly recommend purchasing your equipment from STM you won't be disappointed. (Posted on 1/3/2015)
You've got to see to believe, and here's why... Review by Matthew
I own a small ammo business and I needed a way to process a lot of brass in a relatively short amount of time. This machine completely exceeded all my expectations in terms of cleaning ability, the time in which it takes to clean, the overall noise level (super quite!), and build quality. I know the price tag is a bit high and after shipping it's nearly $900 but I am very pleased with my investment and I'm about to buy another one!
In terms of processing: I process approx. 1,200 rounds of 5.56 (16.5 lbs) per load and found that there was no need to run for anywhere near the 3-4 hour mark to get sparkling clean brass. There's also no need to use anywhere near the 2-4 tablespoons of liquid soap per load. I buy once fired military brass and find that even with as dirty as it is I only need to run with 1 tablespoon of soap for 1 hour! I wish there was a way to attach pictures to these reviews because it's really the only way to show how great the results are. I'll post a YouTube video as soon as I get time.
Fantastic machine guys, thank you so much. I'll have another unit headed my way soon.
UPDATE: The only issue I've had over the last month (tens of thousands of rounds) is that the paint is beginning to peel off the lid around the bolt holes. Wouldn't be a big deal except small rust spots begin to form due to the wet environment of the machine. (Posted on 5/20/2013)
This is the Tumbler Reloading Kit that everyone needs and wants !!! Review by Charles A
Stainless Tumbling Media is just a fantastic company to deal with. They explained the whole process in great detail including the finished result. And every load of brass that I clean with this tumbler comes out just as they said it would, almost like new.

This tumbler is definately heavy duty and very quiet. It also includes a lifetime warranty and is designed to clean load after load of brass.

Thanks again ! (Posted on 2/6/2013)
Great Product Review by DH
Upgraded to the 40 pound unit and just ran my first batch through. The tumbler runs great and the brass came out looking fantastic. If you tumble a large amount of brass this is a worthwhile investment. The barrel is very solid and the base of the unit is very sturdy. This unit actually seemed like it ran quieter than the smaller one. I have the 15 pound tumbler and the 40 lb tumbler and highly recommend both. This is the wave of the future and in my opinion will replace the vibrating tumbler. Great product thanks. (Posted on 1/26/2012)
