I wouldn't say it's 100% stainless, it has some spots where it has rusted a bit, but for its value, I think it's quite good. If you want something better, spend more money to be sure it won't get any rust

I have had it for about a month without much use and without loading more than 100 kilos. After falling 2-3 times, one end got bent. I was throwing it a little lower than deadlift height and I can't understand why. In the end, it's worth getting a good expensive barbell so that it lasts you a long time

It is a cheaply made product, not very well-crafted. It does its job, of course. The cuts on the edge are like they were made with a hacksaw and roughly sanded.
