I own a lot of HF tools and have great luck using them without issues, but the HF pencil grinder I bought literally exploded the city time I hooked it up. Stay away! I bought one com Matco for around $130, and love it.
Just had this discussion with my Matco guy. He said he would warranty the slide or I could buy a whole slide for about $20. He couldn't get just the clip.
I got a couple streamlights at an auction that didnt work. Told my Matco guy about it and he sent them to streamlight for me. Took about 5 weeks, but I got 2 new lights back!
