I actually don’t mind the cheapies:
I try to keep at least one new pair unused unopened. I rotate them out at least once every couple harvests. *Advice: DON’T get the ones with the colored blades, just get the bare metal type
I just feel like that color is scraping off into my scissor hash 
lol!
I personally dislike the curved ones but this is what I was given so I’m using them
BTW Don’t forget to clean the handles and everything, not just wipe the blades with alcohol and/or bleach. Clean the ENTIRE units
