The price difference between tattoo machines and tattoo machines on the market is very large, so in terms of quality, is there a big difference?

The price of the machine lies in its recognition and market reputation. In terms of quality, if the merchant uses "electromagnetic pure iron" also called soft iron in the two parts of the electromagnet core and the hanging iron, then the machine should have no mystery. It's up! Because soft iron is the best material for these two parts.
