Quality:authentic and lightweightSuitability:for basic operations onlyPerformance:very mabagalbagal ng shift+solve. it takes more than a minute before the answer shows up and not very accurate. And also, if I'll calculate one problem on both classwiz and fx991es plus, iba nakukuha kong sagot sa classwiz which is much more accurate. i kind of regret buying it kasi ang bagal and inaccurate ang answers na lumalabas haycurrently taking up engineering btwthe item came safe and free of damage and with free case. :))
