It took two or three days, until my reader showed the first bugs when I bought it (missing pages, flipping two pages over instead of one, ...) so it is a little early to tell, but it is a pleasure to read without any bugs again

On the other hand, the bugs went away for a time when I restarted my reader, so that was no really big deal for me...
Long speech, short on content, meaning: It works right now, but only time will tell
