content: If anyone has experience with these ultrasonic therapy devices:Is there any real differences (apart from reliability, safety standards, medical compliance certifications etc) between expensive ultrasonic therapy devices like this one:http://www.scottmedical.com/item/enraf_sonopuls_190_ultrasound/174/91/49/And cheap Chinese ones like this one:https://www.ebay.com/itm/Pro-NEW-Ultrasound-Ultrasonic-Facial-Body-Pain-Therapy-Relief-Massager-Beauty-sp/282643784618My understanding is that these basically emit the same sound waves with the same piezoelectric transducers.Any real difference in the components different types of transducers or something?

content: Quote from: Axk on January 11, 2018, 11:39:10 pmWhat difference do you expect from cheap vs expensive device if this in principle is not more effective than placebo. EDIT: I know, the difference is by how much money you get ripped off.

content: WTF, from the same manufacturerhttp://partner.enraf-nonius.org/files/Catalogues_Brochures_Leaflets/Enraf-Nonius_electro/Enraf-Nonius_Radarmed_650_950_EN.pdfThis should be outright criminal to sell. It's the same as placing opened microwave oven in front of you. And it's not some low power stuff, almost as regular microwave oven. I would certainly stay away from anything this company makes.https://en.wikipedia.org/wiki/Microwave_burn

content: Quote from: wraper on January 11, 2018, 11:45:34 pmYes, but what about the nocebo effect?Some hocus pocus that has no benefit over placebo. Surely the cheap Chinese device will worry the patient over time in comparison with a more expensive highly shilled device and lead to genuine detriment, albeit to psychological health vs wallet health

content: I used to live in San Francisco and the Sunset District (and the Richmond too) both have large Chinese populations, I don't know exactly what gadget it was, but - right near a popular transit stop on the trolley, there used to be a huge - just a huge building where at almost any hour there would be dozens of older Chinese people getting some kind of (quack?) treatment.The front windows were open and you could see right in. All the signs were in Chinese so i have no idea what it was but they had to lie down for it. It involved some kind of electronic device. maybe it was ultrasound?

content: Funny thing is I bought a broken Bioptron light source at auction, with it having a fault " broken lamp". A quick check and the lamp was fine, power supply fault with a very open small power transformer, apparently a stock fault on these units. A quick look through the " pre tested" pile got a new transformer that fitted, and a quick resolder got it running again.So now I have a really high power, really fancy looking light source with a timer, that seemingly converts 100W of energy to heat with around 99.9% efficiency. It also provides some semi filtered polarised light as well, and currently is sitting in a cupboard doing nothing.
