I picked the Waterdrop 600 ... Now its a little more Expensive but also puts out 600 GPD so is much faster....also puts out only 1 cup of waste water for 2 cups of RO. It looks much cleaner so wife wont mind having it under the sink and comes with a cool faucet to mount on kitchen sink that give a TDS readout of the water.
