It is quite good, only that the handle for some reason is wide and therefore you cannot have a good grip to close it. This can be fixed if you put some tape or something so that it doesn't slip, plus you get scraped by the handle because it has a diamond-like texture

The aluminum for handles doesn't help at all. I wrapped it with insulation tape because it scrapes your skin and doesn't help you do repetitions. Now much better. It's soft until the middle of the range and then hardens abruptly. If you want to do many repetitions, it's not the best because the difficult part is only a 2cm range.

It is very good in terms of quality and very difficult to close.

From the second day it creaks.
I do not recommend it especially for its price.
The texture in the hand is the worst

It is perfect and really useful for someone who hasn't exercised in a while. Anyway, for me, it seems good and worth its money

If you are completely untrained, prefer something lighter to start with.

However, those of you who do the basics and consider yourselves relatively fit, you can gradually take it in 2-3 weeks and reach the point of closing it almost completely. I consider it useless in such cases to get something smaller that you will quickly surpass.

Overall, it seems to be of good quality, however, I have no way to measure if it is actually 90 kilograms or if it has loosened over the time I have been using it. I don't think there is a reason to be so nitpicky.
