Chainsaw Repair

Hello.. I am working on a stihl ms441 and was curious if anyone has any experience with the cheapo cylinder kits from amazon.. Are the worth the time do they last etc.. The kit im looking at is $45 here https://www.amazon.com/Chainsaw-Piston-Cylinder-Stihl-Standard/dp/B07HKQLPQD/ref=sr_1_3?crid=8MCEUD9YA4W9&keywords=stihl+ms441+cylinder+kit&qid=1582687651&sprefix=stihl+ms+441+cy%2Caps%2C194&sr=8-3 Appreciate any comments if anyone knows rather they are ok or just junk and a waste of time and money.

Well its a saw pulled from our scrap pile. Missing covers sprocket etc. Im taking it upon myself to do these projects for experience and to learn how to fix our equipment so we dont have to send them off to a local dealer to fix them.. The cost will be paid for by my boss.. my uncle so im not worried about  spending but at the same time i want to be reasonable and am not going to just blow his money. But i assumed the same thing that it wouldnt be to great so i figured id ask.. there was a chance it could be a cheap option that just works but ill stick with others ive seen that  i know other technicians use for the $100-150  range. Appreciate the advice. Maybe ill try the cheap amazon option on one of our old 170's.

Scrape saw on the cheap. Then it is time to test things.  I've done that on my own saws with a $11 piston before.  GL
