  • Worth FIVE Stars!!!
Size: Ultrasonic Machine Color: Silver
Just had to add to the positive reviews of this great little device! I wasn't sure, at first, if it was worth it, even at the discounted price, since it sounds a bit "gimmicky," the whole ultrasonic cleaning thing, but that's what's great about Amazon, is reading the experiences of others, so I gave it a try, because I have eyeglasses that constantly need cleaning of course, plus I have a few watches that I wasn't really wanting to pay a jeweler to clean and polish. I purchased "Blitz Gem and Jewelry Cleaner" along with this, and that's what I used. The machine worked GREAT!!! Put in the water, put in some cleaning solution, put in my item, shut the lid and hit the button, which has options for how long you want it to clean, and it counts down and shuts off when it's done. Easy breezy! Results were downright unexpectedly awesome! My eyeglasses have NEVER been this clean and I now do this "deep" clean once a week, and it makes it much easier during the week when just cleaning the lenses, since this deep clean makes them look BRAND NEW and gets all the grubby stuff (sorry, gross maybe, I know) off of every crevice where lens cleaning can't reach, so no smears now when I'm trying to clean the lenses. I was honestly very surprised, since it doesn't appear that much is happening. You hear a noise, the water gets warmer inside, and you can see the water start to get slightly murky as dirt comes off your item and into the water, but wow, pull out the item and you sure can see a HUGE difference in cleanliness and it's clear this device is doing it's job. I did my regular glasses, and my sunglasses, and they've never looked better, seriously! I next did a few watches, and for sure this is my new "go to" device for cleaning. Watches looked fantastic, and every nook and cranny was clean and shiny. Again, looked brand new, just like my glasses. And, if you just want to do the bracelet of the watch (let's say the watch itself is not waterproof) you can use the provided plastic arch to keep the watch face out of the liquid. And of course it also has the basket, if you had small stuff to clean, to lift the stuff out before dumping out the liquid. I would agree with others on the one drawback that you do have to take care in dumping it out. Would be great if it had a removable inside container, but it doesn't, and no pour spout. The cleaning basket is cool, works well, and comes in handy to take stuff out before you dump it, but you have to physically pick up and dump the entire machine to dump the water/solution out and my only worry would be, if it was done in a rush or done sloppily (especially because it has no pour spout or anything to help make dumping it out a bit easier), it seems liquid could perhaps spill into the machine itself, especially along the sides where the plastic parts meet (spilled water could certainly get inside). Or, just not holding it tight enough and you could drop the whole thing and maybe damage it. But, ones I've seen with a removable inner container are more pricey, and not as well reviewed, so I was willing to put up with this minor inconvenience, and, thus far, taking care in emptying it, there hasn't been any issues. Just get near a sink, determine which way you're going to dump it, get a good grip (doesn't weigh much, even with liquid inside -- holds maybe a cup, or a bit more, of liquid, is my best guess) and give it the heave ho to quickly turn it into the sink so it's a straight, clean dump of the water/solution. For a mere forty bucks it is well worth it, for sure! Just the ability to clean items so thoroughly, at home, whenever you want or need to, is spectacular and I'm sold for sure on the power of ultrasonic cleaning. No trips to the jeweler means this will certainly pay for itself in a short period of time. I also tried a bit of diluted, mild dish soap, and that worked as well, although the jewelry cleaning solution seems tailor made for the job at hand. I just wanted to see if the solution did a better job than regular soap, and it seemed to, so I'd advise a jewelry cleaning solution -- but even with just soap it still cleaned better than a hand washed effort in the sink, so this truly does what it says! It's honestly not something I ever would've considered buying, until coming across it when looking for a watch, and then reading reviews of it, but I'm really glad I did get it, and thanks Amazon reviewers for sharing your experiences! I HIGHLY RECOMMEND!!! ... show more

  • Big things come in small packages
Size: Ultrasonic Machine Color: Silver
I bought this because I recently started to collect watches, some new some old. I had a watch that I’ve worn to work everyday for the past 8 years. Never been washed. I bought this cleaner and I’m so glad I did. One 8 minute cycle and my watch band, clasp, pins were immaculate. Worked better than expected. Set up and use is very simple and the price is unbeatable. Awesome product, works as well or better than advertised. ... show more

  • It Works
Size: Ultrasonic Machine Color: Silver
I had very high hopes for this machine, as I have seen what they can do for jewelry. I was slightly disappointed after I used it for the first time. I bought some ultrasonic cleaner to put in with the water, and I feel like if I hadn't have used it, the machine would have been much less effective. I started with my three rings (wedding, sterling silver, and gold band), my earrings (ears and nose), and bellybutton ring. I set it for the longest time, and let the machine do the work. I will admit, when the jewelry came out, it was shiny. But I noticed that with my earrings, it did not clean out all of the gunk from the crevices, and where the gem sits in the actual earring. I had to take a toothbrush to finish cleaning them. I also touched up my wedding ring with the toothbrush, because I felt like the spaces between the small diamonds looked a little dirty still. I did use double the recommended cleaning solution, hoping it would make more of a difference. Now, my husband used it on his gold ring and chain, and honestly yes, it did make them sparkle. He cleaned his glasses as well, and the water was quite dirty afterwards. I think this machine will do a good job keeping our jewelry and glasses clean, but if you're looking for something to clean the cracks and crevices, you will still need to do that by hand. It is a machine, and it cannot replace the touch and care of a human hand. But it can sanitize and at least bring back some shine to your otherwise lackluster jewelry! I have not used it on anything horribly dirty, but I can imagine it would do a decent job at cleaning it. Overall, this machine works, but don't expect magical results. Know that you may still have to do a touch up to get it as clean as the professional jewelers do! ... show more
