I ponied up for the unavoidably expensive DHL shipping from Australia to the US, and placed my first order ever with Cutter.
I ordered a bunch of 3v xhp50.3 HD LEDs, both bare and mounted, but Cutter mistakenly sent me a bunch of 6v XHP 50.3 HI LEDs. So I was a bit upset.
I contacted cutter via chat the day I received the incorrect items. They confirmed that the mistake was theirs, apologized, said the mistake was unacceptable, told me to keep the incorrect items, shipped the correct items - also that same day - and asked if there was anything else they could do.
Mistakes happen, but the follow up could not have been better. Kudos to Cutter.
I now have a bunch of extra LEDs which will be dumped/donated to someone who can use them.
