I give the Moogorn 6L Professional 5 stars based on my perceived value. I bought this unit to clean rifle brass for reloading as well as carburators as needed. So far I have only used it on the rifle brass about 6 times and it has proved excellent for this so far. The included drain valve and hose are a great addition and make draining solutions for storage or disposal a breeze. I was expecting it to be louder based on the reviews I read but was very satisfied with the noise level in my unit...However, I did measure the sound level and it was 89db right next to the unit and that dropped 10db to 79db 3' away. The noise frequency is a mix from about 100hz to 18khz so maybe my 65yr old ears are not as sensitive as others. It runs in my shop so it is just not an issue for me, even if I am doing other work in the shop. The unit appears to be very well made in fit, finish and materials. The temperature reading showing the "Actual Temperature" reads about 20 degrees lower than the bath temperature I measured with a thermometer. If that temperature is critical for your application I would suggest you check it with an immersed thermometer.
