Highlights
Quality
I haven't used them as yet but they seem like good quality.
Oddly, i can't seem to find any listings that show the dimensions of the total product.
I ordered the wrong size but they were very good quality
Shipping
I don't know how long they will last compared to the original, but the price is right the shipping is reasonable.
Competitiveness
They worked perfectly as upgrades for my monoprice printer.
Made my a8 run much smoother than the stock bearings.
If you try tightening these on a bolt they'll grind.

I bought these to replace the existing idlers on my anet a8 and unfortunately these were too wide to fit either in the xbracket where the stock idler was or my printed tensioner

The bearings work fine taking load from a belt but theres no spacer between the two bearings and theyre too small to take any side loading
