### ⭐⭐⭐⭐⭐ 







  
  
    Bought for sovol sv01
  

*by K***D on Reviewed in Canada on 12 October 2023*

I bought this for my sovol sv01. I had to file a small amount away so it would work. Took 30 seconds. Its much beefier than the factory plastic one.

### ⭐⭐⭐⭐⭐ 







  
  
    drop-in replacement
  

*by S***R on Reviewed in the United States on 6 December 2022*

Fits and works great.Only note is i swapped the filament guide bearing from the stock idler arm; this replacement arm has a standard bearing instead of the 'grooved' bearing that comes on the stock one. Not sure if that's 100% necessary but seems to me that the grooved bearing guides the filament better.

### ⭐ 







  
    Hält nicht lange.
  
  

*by M***X on Reviewed in Germany on 3 April 2024*

Leider hält das Kugellager nicht lange und die gerillte Rolle beginnt an den Rand zu wandern und blockiert dann ständig.
