I NeeD HeLp PLease AM882 a good choise

It sounds like they're offering you a different brand of rail, e.g. LG or TBI, which is probably fine. Not many people here have bought them yet, so it's hard to compare the quality and even then the differences are likely to be so small it's hard to quantify. The TBI brand rails I got from aliexpress seem fine, so next time I need some I doubt I'll get Hiwin.

I've had several sets of TBI linear rails now and they have been fine and while not quite smooth has Hi-win they are still more than good enough and lot cheaper. I've been using SBC Linear rails n.mnow for years and they have been good never given me any trouble, I run them on my own machine and have punished them quite a bit so know they can stand hard life but the TBI feel and work just has good so I've no reason to doubt they will be just has good.!

Chai is now selling them for those that don't know.!!
