profile rail and purchase advice

hi all. found this on aliexpress
https://www.aliexpress.com/store/pro...732759401.html
and this
https://www.aliexpress.com/store/pro...679338236.html

is this going to be any good, or should I look for branded rail?

John: Those will be perfectly fine any Hobby/semi pro machine but go with the 20mm because they make building easier. Both will easily handle any loads for wood router the size your looking at.

thanks jazz much appreciated
