The best thing about this product has to be its simple integration with your app via Firebase, as well easy setup/easy deployment for new users of it! I had an issue when publishing my application where some files were being ignored by QK (it seems like they dont support certain file extensions). This was very annoying at first but then i realized that qk doesnt really care much what kind or size you upload them in so just go ahead :D It's hard sometimes finding documentation regarding any errors while using firebasereporting features from within our code base - maybe thats because we're still early stage :) But everything else works flawlessly!! We are solving issues related tot he quality control department here which involves making sure all releases pass manual tests before going live / release build process etc.
