Looks good. Thanks for the heads up. Looks like I'll be making my first trip to Aldi.
ETA: Just checked and Camberley is my closest one. Bugger that's a fair old trek. Not sure it is worth the saving over similar items on e-bay.ETA: http://cgi.ebay.co.uk/Ultra-7000-New-Pro-Ultrasoni...
Actually the savingis better than I thought.

I bought something very similar from Tchibo. As far as I can tell, it does absolutely nothing.
However, some time ago there was a news item concerning a claim that wine could be improved by exposure to ultrasound so I used it to test that. The wine did taste slightly different, but I suspected this to be a result of it having 'breathed' better due to the standing waves created on the surface. I drank both the control and experimental samples to be certain, and can confirm that these ultrasonic baths seem just as useless after a whole bottle of wine as they do when sober.

In my first job, may many years ago, we used to use an ulatrasonic bath to clean the boards from the computer rack.However, some time ago there was a news item concerning a claim that wine could be improved by exposure to ultrasound so I used it to test that.

I would second your findings... did absolutely nothing that me or my boss could spot. This offer seems a great way to waste £16 or so.

We use a ultra-sonic cleaner at work for components of 'clean-room' devices and yes they do work, when you buy the best on the market.
HOWEVER a Ultrasonic Cleaner from ALDI for £16.99..... I fancy you'd be better off putting your items in a bowl of filtered water along with your missus's vibrator.

The ones I used at work, worked very well.
I would wager a guess that it has a lot to do with the power of the ultra sonic generators and the frequency.
Also a good cleaning solution helps. Just putting water in will do f
k all.
The firth ones we had used Trichloroethane*(spelling) That really worked. Stood over one of those for years. Then they banned trich for health problems (it had been banned in the states ten year ealier thanks boss)

WE use this stuff, will clean anything off of anything, you can get small quantities, it does leave a white residue on Black plastics

Word of warning about using ultra sonic cleaneres for jewellery
My first job when I left school was a 10 year stint in the jewellery trade in Hatton Garden, worked my way from workshop apprentice to manufacturing supervisor (many years ago !!)
Be very careful when using an ultra sonic cleaner for jewellery, I can recall several instances where various items went in complete with stones and came out very different, as below
Diamonds, have a natural cleavage planes that can be affected by ultrasonic waves resulting in 2 or more parts braking away
Emeralds, are frequently treated with oil to fill natural cracks in the stones, this can be dissolved by the sonic wages, therefore leaving the stone somewhat less clear
Opals, a definite no no as they are porous and react very badly to sonic waves
Coral, again porous, same as opal
Watches, not sure I can recall ever wanting to submerge my Rolex in a sonic bath to make sure all the seals are up to scratch !!!
Bottom line is you should be able to clean most delicate items of jewellery with a soft toothbrush and a drop of fairy liquid in warm water.
Sorry to be a kill joy, dont want to see any one lobbing out to replace the Mrs prized bauble

I used to use a big industrial one in a previous job for cleaning diving equipment and it was ace, with this in mind I got a smaller one to do things like brake calipers, jewellery and my personal diving gear and without a doubt it is crap and that's one that I bought second hand for £100 or so so I wouldn't hold your breath on an Aldi special.
I bought one from Lidl last time they had them on offer (about a month ago) and i've found it great.
I've cleaned watch cases/ case backs, bracelets etc in a strong solution of water and good old fairy liquid. It gets dirt out of the writing on the caseback, and out of all the hard to get nooks and crannies. It was well worth spending the few quid on it.
