(SORRY ABOUT THE HUM... as you can see, I was a moron and thought I was recording into a different camera and mic, so I had to crank up the audio, hence the hum).
This video became more in-depth than I had hoped, but feel free to skip around using the time index. Not exactly a review: basically I wanted to disassemble and examine the budget linear rail that is available from banggood, aliexpress, amazon, etc. Subjects examined are: lubrication, corrosion prevention, disassembly/re-assembly, alternatives, oil vs grease, etc.
2:10 intro and linear guide rail vs v-slot
11:32 cart disassembly and how-to
13:45 machining quality and scope pics
15:34 bearing measurement and spec
19:40 general lubrication rules
23:40 linear rail viscosity note
28:53 household solvent/degreaser overview
32:31 grease overview
35:47 oils overview
36:58 grease experiment and how-to
36:58 TL;DR oil experiment and how-to
43:56 TL;DR initial results and noise testing
45:48 TL;DR do they suck?
