I have less than 10 hours use of the machine but the purchase and shipping went smoothly. The freight charge seems a little steep as I often buy larger heavy machines that don't cost nearly as much to ship freight to me. Set-up is easy with the step by step instructions. The cart is a little awkward with the high center of gravity but the wheels pull fairly easily. On initial start up my TDS was around 300 and this unit took it down to 3. As far as filter life and easy of changing I don't know yet but based on the research I did before purchasing it is about what I would suspect. Also with a PSI of 50 it barely pushes water through the pole on a 1 story home. The pump is basically required 100% of the time to get sufficient water to wash a window.
