  • It seems good quality
The part arrived in great condition and seemed to be high quality. onfortunately for me I ordered the incorrect part. Too lazy to return it but if it was the one I needed, I'm certain it would work great.

  • Not a perfect fit for my SC 400
The adjusting screw and gear needed to be replaced since mine got damaged. I ordered this kit and it does work just fine but it's not a perfect fit to replace the damaged one but its just close enough that it fixed my problem.

  • Fixed my Echo CS-400
Old tensioner broke on my Echo CS-400. I can't even remember which exact part failed but I ordered this and had it the next day. I replaced all the tensioner parts and I've cleaned up a bunch of storm damage since and this has held up great!

  • Not identical to 590
I was looking for the adjusting screw/gear to replace the one on my cs590 that got damaged. This kit contains one that's close enough to work; not identical, but close enough.
