Aucma Ultrasonic Cleaner Professional Industrial 180 Watts 2.5L Heated Ultrasonic Cleaners with Digital Timer for Jewelry Eyeglasses Lenses Necklaces Watches Rings Denture Coins

Easy to set up and use. Just pour tap water into the chamber, select the length of cycle and whether you wish heating on and press go. Seems robust and no reason to believe it won't last.I cleaned a diamond ring and thought it made a huge difference to the area under the stone. In line with reviews I've seen I tried it with my spectacles. It made a great job of cleaning the nose pads but I noticed fogging on the lenses, which I took for condensation. When it didn't simply wipe off I examined them with a magnifying glass. I now believe the protective coating they were supplied with has been partially removed, mostly near the edges. I'd recommend removing and cleaning the lenses manually and only do the frames in the device. I'd also be wary of using it on items with decorative finishes.That minor niggle aside, I'm delighted with the product and expect to use it regularly.

First impression with this ultrasonic cleaner is that it comes with heating, that is not so common among same price range. Seems to do its job decently, however it has some design choices that are not-so-convenient. Of course you cannot expect the same cleaning level as a fully professional unit, so you may need to repeat the cleaning several times or complement it with some other chemical/mechanical procedures.The unit is silent enough, with a fizzling sound that comes when the ultrasound is on, and fans when heating is enabled. Easy to use as you only need to fill the tank, place the items, plug the unit, enable heating if wanted to use it, select the time from the 5 options (up to 8 minutes), and start. While working, it displays the remaining time, and at the end it stops automatically... but only the ultrasound, not the heater! At least it has a safety operation that prevents overheating, but from one occurrence I believe the safety system stops everything, including the ultrasound, before the end of the timer has been reached.The heater is only on/off (60-65 degrees) so no way to select specific temperatures.Note that you only need to cover your items to clean with water, it is not needed to fill the full capacity of the tank. It is possible to operate it without the lid for submerging larger items partially.The basket is very shallow and only covers the bottom for protection, with tiny handles at the bottom that may make you to swing the load to one side. Reaching the basket handles may be unpleasant when you enabled the heating, so I use rubber gloves for picking up the items.Another thing I don't like is that the tank top rim is covered by plastic edges -- does not seem to leak but dirt could be stuck there when pouring out the dirty water.I have yet to try with de-ionised or distilled water, as I read somewhere that it could improve the cleaning.

Item was purchased to help remove grime, grit and dirt from small bicycle parts. While the unit fizzes away sounding very industrious and purposeful, the end result is, well, no different to when the item goes in even with a recommended cleaner added to the water. Even with temperature applied and set to the maximum 480 seconds of cleaning time (also cleaned some items for 960 seconds) and quite literally, no difference even with relatively minor grime to the parts. Overall, rather disappointed with this unit and would not recommend.

Looks well made, plenty of reviews on You tube. I have not used it yet but looking forward to doing so. Same unit sold in america under a different name.

Unpredictable results on my watches. Jewellery came up greatOther items cleaned were hit and miss.I would suggest using clean fluid as washing up up liquid not perfect or guaranteed to give you the best results

So far so good it does exactly what I needed it for and worth the money.

Buying an ultrasonic cleaner can be tricky because there aren't that many on the market. The cheap ones look like toys and expensive ones look industrial. This was a good half way point.This one was purchased for a salon to disinfect tools before sterilising in an autoclave.Performs noticeably better than a smaller one we had (you can actually see the dirt coming off the tools from the first few seconds of operation).Heating function works great and timer works flawlessly.Noise is a little high but still quieter than the previous one we had.Only negative is that it's a little pricey but in my opinion was worth the upgrade for a small business taking hygiene seriously.

TARNISHED SILVER JEWELERY IS HARD TO CLEAN,MACHINE TOOK OFF MOST OF THE SOIL A LITTLE BUFFING FINISHED THE JOB.
