As we have found previously, this company fills orders quickly and efficiently, with the product well packed.
This unit was more compact than expected, so I am pleased we did not buy the smallest version.
It was purchased to clean jewellery and eyeglasses. When reading various detailed instructions on how to use these units, they always specify that you separate items and try not to touch the bottom of the unit tank. Under those circumstances, only one pair of glasses can be cleaned at a time and some larger frames eg. sunglasses simply don't fit. If that is your intention - buy a larger model. When doing glasses, it releases the grime in tiny corners like lense frames, nose pads etc that you can never clean manually.
It uses the standard frequency which is quite gentle on items but does the trick. Diamond and other jewellery comes up sparkling.
In short, aside from the size caution, I would recommend this to anyone wanting to clean glasses and jewellery.
