    Delivery without problems as expected. But it seems they are from different makers. Two of them (which are identical, brighter green sleight ) working fine after little extra lubrication, one (which are little bit smaller width, darker green sleight) is sticking always on the same position. Tried to move the sleights which show the difference between. the sleight of the good one has a tiny gap on the track of the bad one. The two good ones had a stop plug on both ends, the bad one just cable ties. It seems it is a cheaper made or known as faulty. Even so at the bad slight looks like one or two steel balls are missing. All over I'm not really happy, try to find a proper retailer for it. cheers

    Mir war klar, dass diese Linear Schienen mit den originalen von Hiwin nichts zu tun haben. Aber ich war gespannt, ob nach dem Zerlegen, Reinigen, Zusammensetzen und anschließenden Ölen etwas brauchbares herauskommt. Danach konnte ich eine signifikante Verbesserung in der Leichtgängigkeit feststellen. (Vorsicht ! Dabei bloß keine Murmel verlieren !) Für die Belange beim 3D-Drucker reicht es auf jeden Fall.

    I bought one 400mm for test. It came just in a plastic bag, no bubbles, no foam, no cardboard. Just a plastic bag that was sticking out of the bigger bag (see photos). Also, I bought it from the UK warehouse to EU, it was advertised that it would take 3-5 days to deliver, but surprise, it took nearly a month (!!!). Now to the rail itself. The bag it came in was sealed, but the rail was full of dust. Because of the poor packaging, I think the rail is slightly bent. Unfortunately I have no tools to measure it, but if you put it on a flat glass surface, you will see that it forms an arc, and some light is passing under it. When I first tried to slide it, it got stuck several times and it felt like it was scratching along. I disassembled it and washed everything in IPA, put it back together and used some silicon oil to lubricate it and now it is a lot smoother and nearly doesn't get stuck when you let the block fall freely vertically. It still feels a bit scratchy though. I don't know about the quality of the metal itself, for reference, you can scratch the rail easily with a wiha picokit screwdriver or a bosch hss drill bit. Overall I think it is ok for the price. I'm going to buy a few more of these. Good luck!

    Ok product but the packaging was not good enough, the rails came in a plastic bag without any bubble wrap or cardboard to protect the rails and blocks. All of the rails were bent and the blocks had seized on the rail plastic stop, which damaged the red rubber seal.

    Hi, the banggood packaging is insanely good and the parcel arrived without any damage. 400mm Rails are straigth, clean and strong for this tiny size. On the other hand the ball-blocks look a bit fragile, if you are not careful, some balls can escape their track, but they slide smoothly on the rail, i will clean them properly, i have seen people on youtube explaining the cleaning process and getting great results even when the carriage is completly stuck. For some reason, It seems the package contents violates some european union import regulation article 28/29, i dont know if this is a big problem for future orders, the package arrived in time anyways. I will definitely purchase more of these rails for future projects.

    I bought two of them. The first one i used it after I disassembled and cleaned it. So far it seems to be working well. The second one i also disassembled to clean it beforei used it. The linear rail guide has marks from bearings (you can see in the pics). I reasembly it and lubricate it . The movement is not so smooth and when you move the block you can " fill" in some places the grooves.

    Качество весьма хорошее, рельсы ровные, каретки нормальные. Из упаковки ход не настолько мягкий, как хотелось бы, но смывка заводской смазки и замена ее на нормальную изменят ситуацию. В сравнении с уже имеющимися у меня рельсами (покупал не в этом магазине), новые рельсы самую малость им уступают. Но, повторюсь, нормальная смазка им необходима.

    I am no expert on linear rails, but after cleaning off the old oil with isopropyl and regreasing with ptfe lube those run very smooth and silent I used two in parallel to upgrade my ender 3 y axis
