I bought a parkside sliding mitre saw in 2020 I think it was, it broke the same year, it's still in the shed, I hope to find the receipt for it one day!!Someone gave me a parkside mitre saw in 2010.
I have tried to kill it by using it every day even to chop small logs.
No chance!
The other day I was building a frame and changed blade.
Then I checked if it was still square: it was.
I never had to adjust it and I changed brushes only twice.
A freud blade lasts me for lots of jobs, so probably it's just a matter of using a good blade and knowing how to use the tool properly.
Or...I've been lucky.
I'm do have a couple of other parkside mains power tools that are still working fine (for light duties). You get what you pay for.
