title_body: How to (easily) get the back cover off a $35 Polaroid PER7021 e-reader? I have an e-reader I picked up at Big Lots for $35 and it's a great machine, aside from two problems: 
  
  
  It eats through batteries when turned off.
  The battery cover doesn't remove easily without using a butter knife.  
  
  
  I think that the former problem could be resolved if I could just take care of the latter problem.  
  
  What do you do about this fellow PER7021 e-readers?
upvoted_answer: Try using an iSesamo — it's a tool explicitly made for popping open the panels on electronic devices (www.newertech.com/products/isesamo.php)
  
  The iSesamo is thinner than plastic spludgers and sits in a sweet spot between stiff/inflexible and too-bendable-to-pry-things-off.
