Trolley jack plastic castors

[grumpybadger]

I'm currently looking to replace my trolley jack and have noticed that a lot of newer ones now have "heavy duty" castors.
This appears to be code for resin or plastic.

My garage floor is far from showroom and this I have some misgivings about these


Anybody have any experience of these?

They roll better and are much quieter, that's about the only benefits.
