IT IS A NICE PRODUCT, BUT VERY HEAVY. I WAS GOING TO USE IT FOR A PORTABLE TOOL, TOO HEAVY!

Die Lager laufen nicht sehr leicht und geben ein Geräusch ab das wahrscheinlich nicht normal ist.

Ok

Tutto regolare a parte un cuscinetto che non scorre bene, leggermente difettoso!

They work well but did not come with screws or any info on the type of screws to buy.

Theses rails work very well. I am using them vertically and they slide down very easily. However, some of the ball bearings have fallen out of the guides, and the guides are partly plastic, which means they will wear out long before the rails do. By the way, how do you order replacement bearings?

Pretty weak

Ein Paar Schienen waren perfekt und das andere Paar war leicht windschief. Schade dass ein Umtausch so umständlich und kompliziert sein muss. so habe ich mich halt damit arrangiert und werde in Zukunft meine Ware anderswo kaufen.

Excelent product.But at the time when I placed the order delivery time was 4 days.It took 9 days with 5 interventions at customer service and I heard all kind of excuses.For that problem I asked for a discount on my next purcese but they ignored my request.Product 5 stars and all around service 2 stars.I am dissapointed.

I tried so many tricks to get the rail blocks to glide smoothly with no luck. I tried oiling the balls and adjusting with adjustment screws before realizing the shaft is bent and the blocks are simply low quality. I bought the linear rails here instead of eBay because they promised attention to detail with certain defects like mounting holes location and such but it turned out it is the same product on eBay except you don't get any hardware.
