I am sure it's a good product, if you can get through...
For MIDI MERGER / SPLITTER 2in->5out Thru PCB or Kit
I am sure it's a good product, I ordered two kits, some of the IC's from the first kit didn't work, so I took chips from the second kit, I got it to work for a short time, but it eventually quit working. The main problem/gripe is that the tinde website wouldn't allow me to contact the seller "privilege restricted". So, if you are kinda new to DIY and might need tech support, I would suggest you go somewhere else, if you are more advanced and can trouble shoot go for it!!!

Hi Howard, there are absolutely no restrictions contacting me for the support. You're welcome to contact using Tindie (if it's a problem, then get support involved) or Github (where all schematics or source codes) or even a Youtube page (where tutorial videos are). Let me know the problem and how I can help.
