Buy a genuine Prussa made i3.

Thing is, people don't look beyond the price of the printer when making a decision. Most of the Chinese printers, even the good ones will have variable quality. Some will be outright junk.

I bought a cheap Chinese printer with a relatively good reputation and I'm replacing some parts right out of the box because the quality is just not there. It works for me because I have not problem fiddling to make things work and when done, I will have a $2,000+ printer at half the price.

You get what you pay for and you have to be prepared for the extra work to bring a cheap Chinese printer up to good working order.
