Aside from the obvious manufacturing flaws showing lines from the microphone holes that look like visible repaired fractures, I only had a few issues. You can't close the lid quickly once it's opened. In other words it would be nice to be able to give it a command while it's opening. You can't close it at all if you are in it's detection field. An override would be nice. It's difficult to remember the 3 vocal commands from day to day. It's a bit difficult to pull a new bag from the dispenser. Maybe layer them so the end of one starts to pull the next like tissues. Or fold them such that an end is easier to grab and pull. I'm reluctant to clean the lid knowing it might damage the microphone and motor. It should be able to handle a spraying hose of water. I like it overall but it still has some room for improvements and it seems over priced.
