Scott, they are not that bad, I have been using them since they came out..They have a bad spot if you lean on the corner as mentioned, but I use real keyboards that have a little weight to them, and they stay put..Warranty is the absolute best in the business, they replace any part free of charge including shipping, usually overnite. They are friendly and courtious..I would recommend the company.. I am using the Super Apex currently in our band, as the girl keyboardist is using one too..
