Digital Small Ultrasonic Cleaner 35W for Jewelry Jewellery Ring Eyeglasses Lenses Dentures Watch Necklace Coin Cleaning

i have put several silver tarnished necklaces and a ring for several minutes now over and over and it did not remove anything...they look the same...i started reading about cleaners and basically it only gets rid of the goop and not tarnishes...if i have to buy chemicals than why do i need this? so i suppose it is great for removing dirt like the sonic toothbrush but as for tarnish or any chemical reactions on metal didn't touch it...thought it would at least weaken it making easier to remove --nope...so anyone who said yes to this removing tarnish is lieing...it doesn't. it is only for grease and dirt if that...kind of a waste of money in my opinion...if it doesn't clear everything and i still have to scrub...not worth it to me. i gave 4 stars because packaging was great, looks like a sturdy little machine but minus one star because doesn't make my life completely easier may even be returning going to buy jewelry cleaner and try it again if it works then i'm keeping it but if not going back.

So, I bought this to clean resin 3D prints. It works perfectly well for this use case. I put prints in with liquid resin residue, and 3 minutes later they no longer have liquid resin residue. It comes with a strainer which is useful, has an easy to set timer and does what it’s supposed to, so I’ve been pretty happy. Be aware that this is a pretty small unit/tank. Most of my prints are 25mm scale minis and they fit just fine, but larger monsters are tight fits. All and all I’ve been satisfied with the purchase. It hasn’t “wowed” me but it’s not really the type of product that is going to do that. I have no real complaints either.

Effectively cleans small items. Fairly quiet in comparison to sing.the ultrasonic cleaners of its size, as well. They're not screwing around with the power cord either - that thing is heavy duty.

Came very well packaged and works much, much better than our old one which didn't last long at all. All metal and simple to use, it's just what we needed. No issues.
