The blinking light means the tablet has power but does not see a connection to the computer. Please disconnect the tablet from the computer, and restart. Once the computer is booted back up connect to another USB port. If you are using a Windows computer you should see a message that says "Installing device driver" this is part of windows that needs to install to use the tablet. If this fails, try running your windows updates and try the steps above again. If you have a mac computer, there will be no driver driver message but it may take 30 seconds or so to stop blinking. If in either case it does not, please contact wacom support .
I don't recommend the low-end Wacom Intuos. It's got a small drawing area (smaller than all the alternatives with the same price) and the only reason it costs so much is because you're paying extra for those bundled programs it comes with. Without those, the tablet itself is only worth ~40-50 USD, so if you're not getting it for the bundled programs, you're basically getting cheated into paying for programs you're never going to use. It also isn't any better in build quality than the alternatives as far as I have seen so I see no merit in choosing Wacom unless you're getting an Intuos Pro or Cintiq specifically for the pen tilt/rotation features.
I would personally recommend the XP-Pen Deco 03 if it's available in your region and you're willing to spend 100 USD because of its like-Intuos Pro comfort.This is my favourite screen-less tablet at the moment because it has the best pen pressure and drawing experience I've had so far. I don't find the advertised red dial very useful and the wireless is "eh", but if you ignore those side features, the comfort of the pen and the control you have over the pen pressure are absolutely fantastic.
