Don't buy this. Like the rest of the reviews mine broke within 2 seconds of using it for the first time. Unfortunately I only tried to use it 2 months after delivery, hence no return and money thrown into the sea. The supplier did reply with a ‘cannot accept return’ reply . As another reviewer said, “look somewhere else”.

Only lasted about 6 months before failing - screen and timer worked, you can hear it click when switched on but the actual mechanism stopped working

I purchased this product to clean my eyeglasses, but after the first use as instructed in the user manual, the protective layers of my lenses were removed and I had to pay 10 times the price of this product to replace my damaged lenses.

Don't buy this. Like the rest of the reviews it broke within 1 minute of using. It is 110v but comes with converter. Look somewhere else.

I used the machine only one time. 3 cleaning and it never works again. Poor quality. Single use tool.

I have a small cleaner that I use for my mouthguard but I wanted a bigger one to use for jewelry and also to put some soap in occasionally for cleaning. This machine is on the big side but I have found it very helpful and I've used it for a variety of things such as larger necklaces and even eyeglasses. My only negative would be the directions are slightly confusing I didn't understand the pulse feature so I never used it but overall happy with my purchase.

Me gustó mucho la máquina de ultrasonido, limpio muy bien mis joyas, la recomiendo ya que es pequeña no hace ruido y está a un excelente precio.

Please see bottom of this review for photo description.Ive been using this for a little while now, purchasing it initially for the upcoming season of working on the car, lawnmower ect. In the meantime, ive been using it around the house, on various things like my grandfathers old jewelery, tools, camping knives, basically anything that has crevices where you just cant get a brush in to clean properly. A big test for ultrasonic cleaners to ensure they are actually working is using tin foil, place it over a support and put it into the cleaner. After a few minutes it will start to perforate and essentially disintegrate. I included a photo below which verified its function.It works like a charm, cleans everything I put in very thoroughly on two 480 second intervals. It functions just as id hope it would, removing stuff that you cant see or cant access, I think the worst thing was an old nail clipper I cleaned that looked super grungy before from dust and rust, but now it almost looks like a new one. I wish that it were a bit bigger so i could fit more things in it to be honest. The bin is roughly 6 inches wide, about 4 inches deep and 3 or 4 inches tall.... Big enough for the small stuff but not big enough for a carburetor from a car. None the less, it works great and I have been very happy with it.I found it works well with both degreaser, usually a half cup of spray nine in with the rest water for heavy duty stuff or a few drops of dish soap for light duty. You need to be sure to degas the water before use, it removes any bubbles which will otherwise absorb the ultrasonic waves... It works 10x better after degassing. I also find that it works best without the included white plastic basket, but you may decide to use it.Anyhow, I wholly recommend this cleaner. i am extremely happy with it, its been very reliable and functions well. I will update this review if I have any problems with it.PHOTO 1- Tin foil before putting in machinePHOTO 2 - TIN foil after 1 x cleaning cyclePHOTO 3 - NAIL CLIPPERS BEFOREPHOTO 4 - NAIL CLIPPERS AFTERVIDEO - SHOWING VIBRATIONS WITH JEWELERY INSIDE

I like this machine. Very easy to use. I use it mostly for giving my fountain pens a good clean. It will, of course, clean jewellery very well.

For normal use for glasses, small item or items with aged dirt, it works pretty good for cleaning, but if items that with aged dirt or hard dirt, can't clean if not use cleaner with it.
