Is the laser therapeutic instrument a scam?

If talking about toxicity accidents is hooliganism, then talking about radiation accidents is also hooliganism. Brush can write and draw, which is a function problem. It is normal for an ordinary brush to cost 5-50 yuan, even 500 yuan. But selling you a brush for 50 thousand to 50 thousand to say that you can become a master of painting and calligraphy is a bit far-fetched After buying it, I found it too small to write couplets. This is a question of power. Laser acupuncture is the same as general acupuncture. If the power is small, it will have no effect. If it is too big, it will be out of control and there will be risks. Ordinary silver needles have the same problem. Shallow needle has no effect, and needle width is risky. Even if they are right, they are deep in the calf, but these parts are not important. You said that if the needle is deep, there is no risk. Can you believe it? The laser is powerful and can cut the steel plate. However, I won't sell it to you for laser physiotherapy for thousands of dollars and tens of thousands of dollars! But it is really not a problem for hundreds of dollars of laser to burn skin and muscles. The key point of technology is to control the profitable cost, control the effect without causing harm, or try to control the harm without affecting the curative effect. This is a technical product and a technical company. Here comes the problem. Many unskilled companies train their salesmen through low cost and high incentives. Where are you going to check this situation? Professional laboratories cost thousands of dollars, but they are only responsible for testing power and wavelength, and the curative effect is unpredictable. Traditional acupuncture is questioned today, and the big factor is either technical or metrological. If the product itself is a waste of money, buying it is also a lesson. Whether it is a silver needle, a stainless steel needle or an embroidered needle, there is a grip method. At most, the needle mouth is a little bigger and the pain is just as effective. Find a butcher, or a tattoo artist, or even a gold needle, a platinum needle or a diamond needle. Besides buying an expensive one, I also bought a painful one by the way. Finally, regardless of the product performance and the professionalism of the operator, simply answering whether it is deceptive is deceptive.
