For the price, I am not sure you can beat this. Cool piece of equipment to have, especially for a hobbyist. Price is right, easy to set up, the motor is definitely powerful enough to stir 1000-2000ml for extended periods. I am very pleased with this. Oh, one thing, I did end up ordering another stir rod on ebay that is PTFE coated and a little longer, although the one that came with would work great for 500ml round bottom, the shaft is a bit short for 1000ml+
