Customer service still exists! Or US Divers / Aqualung rock

I got some snorkel gear last month at Costco. I didn’t necessarily expect much..thought “cheap costco gear”, though they weren’t exactly inexpensive and as I used them I did actually think to myself, “wow this is actually really nice gear.”
Except I had a fin break the first time I used them (looked like manufacturing defect in the plastic upon closer inspection by my lay person eyes). Monday I exchanged some email with the US Divers parent company Aqualung. Today I received replacement fins in the mail.
I’d about forgotten such great customer service exists. Certainly not what I expected originally and quite a pleasant warranty replacement surprise! Definitely the type of thing that makes you recommend a company and their product to others.
