I purchased the 9002 model from a local pet shop and put it in the tank and noticed that the cup and the main unit had ALOT of hairline cracks like splits. I was going to be ok with that and just go with the flow. Then I noticed that the pump was making a whining noise and noticed that the temp was up in my nano cube by 4 degrees! I pulled it out and took it back to the pet shop, WELL at the pet shop they told me that they have stopped carring this brand and so I was stuck now. I would like to get this whole unit replaced. I just cant beleive that someone put this unit in a box, it is worse than a Fission that I own...and thats saying alot...someone from there get in touch with me...Please!?!
