Seeed Studio Waterblock
I purchased a water block for a raspberry pi 5. It was and still is advertised as having G1/4 threaded ports. As I have been water cooling for nearly 25 years, I have a lot of excess parts and was interested in watercooling a cluster of pi's. I purchased 2 of these blocks and gathered the rest of the parts for the system. Once received, I removed the original barbs and immediately noticed they were not G1/4. They were actually G1/8. I sent an email to support with a picture of the G1/4 fitting I owned next to the original fitting supplied. They replied that the ports should be a standard G1/4 (which is why i purchased them) and referred me to the installation wiki and if I had further issues to send pictures. I don't need a wiki to screw in a fitting that is too large for the thread its intended for. Also asked me to send pics if I had further issues, which I had already done with my initial support request. Postage was extremely fast. China to Australia in 1 business day. But their lack of support and clear error in advertising is disappointing.
