Most people love the Maxijet line of pumps. I myself have had bad experiences with the Maxijet 900. I have have had 3 of them in the last 9 months and 2 of them just quit working. I was however able to replace them easily under warranty. The 2 I have now are working fine. I do believe though that the housing is kind of cheap and the air intake tube keeps falling off. I use mine for mixing new salt water and the unit is always falling off the side because the suction cups are not very good. Remember these are the 900 model. The 1200 model may be built better but I don't know.
