Drawing Tablet :(

I do not recommend this drawing tablet. I bought it a couple of months ago and at first thought it was a fairly good drawing tablet. I've only used it a few times and today I plugged it into my computer because I wanted to edit a screenshot and I realised that the nib of the pen was stuck inside the pen and the buttons were stuck too so I couldn't use it. I've looked after it well and I just keep it inside one of the pockets in my laptop bag so it should've been okay. So I've emailed the company and I'm going to try and get a refund so I can put the money towards buying a better one.
