Review on Ultrasonic Cleaner, Jewelry Cleaner Portable - 600Ml 50KHz Low Noise Ultrasonic Machine For Cleaning Eyeglasses, Ring, Jewelry, Watch Chains, Retainer, Razors, Dentures Combs (UTEN-Black) by Nathan Issa

Like a bunch of people, I picked this up to clean gun parts, specifically BCGs and suppressor baffles. With not that much carbon build up, after going through 30 mins total of running the thing (annoying as hell with a 3 minute time) the parts were not notably cleaner in general, and the only carbon that had come off was that which was already flaking off before the parts went in. Unfortunately it's just not capable of cleaning parts quickly, and since it's locked at 3 minutes, you can't start it and walk away. Going to have to recommend people pass on this one, and I'll be returning it tomorrow.
