The telescopic tube clamp on my PCS-9 recently cracked, much to my dismay.
Hit up the Park site to inquire about a replacement, sent off the email about availability, cost, etc.
Next afternoon (on a weekend, no less) I get a return email simply asking for my mailing address, and they would send out a replacement.
A few days later, the part arrives in the mail, no charge to me.
That's a quality operation they're running, for sure.
